Executive Summary

We present radiogenic crustal heat production values (~1500 determinations) calculated from available geochemical data (from OZCHEM, published literature and unpublished data) for samples taken from exposed outcrops from the Australian Antarctic Territory (AAT). Crustal heat production is derived from the radiogenic decay of the radioactive elements, primarily, U, Th and K. In this report, we briefly assess the magnitude and heterogeneity of crustal heat production across the major regions within the AAT. This information has been compiled as a foundation for future, more comprehensive, geothermal heat assessments of the AAT (including heat flow mapping) for the purposes of ice sheet modelling studies addressing the dynamic behaviour of the east Antarctic Ice Sheet.

Introduction

GEOTHERMAL HEAT PRODUCTION, HEAT FLOW AND DYNAMICS OF CONTINENTAL ICE SHEETS

The Antarctic Ice Sheet (AIS) plays a fundamental role in the dynamic and complex interaction between global climate systems, ocean circulation patterns and sea level change. The dynamic behaviour of the AIS and ice mass balance determinations, particularly in the context of anthropogenic global climate change and the potential impact for sea level rise (e.g. Fox, 2010), requires an understanding of the magnitude and heterogeneity of natural boundary conditions affecting the ice sheet behaviour and ice drainage systems. Sub-glacial geothermal heat flow, the natural heat flux through the Earth, is widely acknowledged to be a critical, yet poorly constrained, parameter influencing ice sheet behaviour (e.g. Waddington, 1987; Siegert and Dowdeswell, 1996; Llubes et al., 2006, Pattyn, 2010; Maule et al., 2005; Pollard et al., 2005; Winsborrow et al., 2010). In spite of the importance of sub-glacial geothermal heat flow in influencing continental ice sheet flow behaviour, there is little, if any, direct empirically derived heat flow data from the East Antarctic continental basement. This is not surprising as obtaining direct information in ice-covered regions is difficult and expensive. In the absence of heat flow determinations, many studies utilise broad estimates based on 'average' global continental values to make assumptions of the heat flow of the continent beneath large-scale ice sheets for use in ice sheet models. Typically these estimates range between ~42 to 65 mWm-2 for Precambrian crystalline basement (e.g. Sclater et al., 1980; Waddington, 1987; Pollack et al., 1993; Pollard et al., 2005; Greve, 2005; Huybrechts et al., 2007; van der Veen, 2007; Thoma et al., 2008). Other studies estimate the magnitude and distribution of heat flow in Antarctica from deduction using low-resolution global seismic tomography data (Shapiro and Ritzwoller, 2004), satellite-based geomagnetic observations (e.g. Maule et al., 2005) or from the inversion of air-borne gravity measurements (e.g. Studinger and Bell, 2007). These methods assume a thermally homogeneous crust and geothermal heat flow estimates are effectively a function of crustal thickness; a thick crust equates to relatively low heat flow; a thin crust, high heat flow. These generalised approaches for determining sub-glacial heat flow, although widely utilised in ice sheet modelling and ice mass balance studies, fail to account for the significant thermal heterogeneity within the crust where Heat Producing Elements (HPEs; U, Th and K) are concentrated. Regional and local variations in the amount and distribution of the HPEs, and therefore local geothermal heat production, are known to significantly impact heat flow (e.g. Neumann et al., 2000; McLaren et al., 2002; Jaupart and Mareschal, 2004; Vilá et al., 2010), thus an understanding of the heterogeneity of crustal heat production will form a primary basis for better estimating variability of heat flow (in conjunction with further studies) in the Antarctic crust, a critical parameter in appraising ice sheet dynamics. AIMS

This report presents a compilation of ~1500 heat production determinations from across the Australian Antarctic Territory (AAT) based on existing geochemical data, mostly sourced from Geoscience Australia’s OZCHEM database. The data are used to illustrate the magnitude and range of geothermal heat production across the AAT. Furthermore, we seek to highlight the inherent heterogeneity of crustal heat production from all regions within the AAT in order to provide better constraints on important future heat flow mapping work, thermal modelling of the Antarctic continental crust and impacts on the possible implications for ice sheet studies.

Background

CRUSTAL HEAT PRODUCTION OF THE AUSTRALIAN ANTARCTIC TERRITORY

Surface heat flow is dependant on the heat derived from the natural cooling of the earth’s interior (core and mantle) and radiogenic heat generated within the upper crust by the radioactive decay of the major heat producing elements (HPEs); U, Th and K. More than 98% of the contemporary heat production in rocks is derived from the decay series of naturally occurring 238U (~99.3% of naturally occurring U) and 232Th and the single step decay of 40K. Other isotopes of U (e.g. 235U; ~0.7% of the present day naturally occurring U) and other radioactive elements with extremely slow decay rates (such as 147Sm with half life of ~106 billion years) do not contribute a significant component to the Earth’s heat production budget and other, short-lived radioactive isotopes, may have contributed to heat production early in the earth’s geological history but are now insignificant or undetectable (Slagstad 2008). Radiogenic heat production is a major factor determining the thermal structure of the continental crust. Due to the incompatible nature of the HPEs in mantle rocks, U, Th and K are preferentially accumulated, by geological processes, in the highly differentiated, predominately felsic, continental crust. Therefore, as concentrations of the HPEs within the continental crust vary considerably, the heat production is correspondingly variable. There are few, if any, direct empirically derived heat flow data from the East Antarctic continental basement. This is not surprising as obtaining direct information in ice-covered remote regions is difficult and expensive. However, in order to provide a first order illustration of the potential thermal heterogeneity of the east Antarctic crust we have determined and compiled ~1500 heat production calculations derived from existing whole rock geochemical analyses across the Australian Antarctic Territory (AAT). This compilation represents the first known assessment of its type from surface exposures in the East Antarctic continent. We show that individual whole rock heat production values vary by a factor of as much as 30 within the major geological provinces of East Antarctica and that heat production is broadly, but not always, correlated with geological age. This compilation illustrates the considerable local and regional variation in heat production due to highly variable distribution of the HPE within the Antarctic crust. It also shows that a thermally heterogeneous crust assumed by many ice sheet investigations is inappropriate. The information in this report may form a foundation for subsequent investigations exploring the natural heterogeneity of crustal heat production and sub-glacial crustal heat flow of the Antarctic continent to facilitate development of more informed models of ice sheet behaviour. This is a topic of particular relevance in the context of current concerns of the potential impact of anthropogenic climate change and potential for sea-level rise. METHODS AND LIMITATIONS

We determine the heat production values utilising the bulk rock heat production equations from Turcotte and Schubert (2002; equation 4-8, p.137), incorporating the two principle isotopes of U (238U and 235U at 99.28% and 0.71% relative abundances respectively), natural thorium at 100% 232Th and 40K at 0.0119% of naturally occurring K. We use the isotope decay heat production values (W kg-1) used by Turcotte and Schubert (1982, p.140; cf. Turcotte and Schubert, 2002, p.137; Jaupart and Mareschal, 2004). The heat production values determined for a given bulk rock is therefore a direct function of the U, Th and K abundances of the rock as determined from whole rock geochemistry. Although one can assess heat production through geological time (utilising the known decay constants for 238U, 235U, 232Th and 40K and ‘back-calculating’ the concentration of these isotopes for

3


any given time in the past; Turcotte and Schubert, 2002, p.137), we only calculate the heat production value for present day (t = 0). The heat production determination is therefore simply, for the case that t = 0 (present day):

H 0.9928C U0 H U 238

0.0071C U Th Th 40 H U235

C K40 K40

0 H 1.1910 C0 H D (1)

Where H is total heat production of a given rock unit, C U0 is the concentration of U in the rock as

measured (by weight, parts per million, ppm), H U 238

is the heat production from the isotope 238U

(9.37 x 10-5 Wkg-1), H U 235

is the heat production from the isotope 235U (5.69 x 10-4 Wkg-1), C Th0 is

the concentration of Th in the rock as measured (by weight, ppm), H Th is the heat production from

the isotope 232Th (2.69 x 10-5 Wkg-1), C K40

0 is the concentration of K in the rock as measured

(conversion to K ppm = K K40 40 2O wt% * 8301) and H is the heat production from the isotope K

(2.79 x 10-5 Wkg-1). D is the assumed density of the rock at 2700 kgm-3. All heat production values in this report are given in units, μWm-3. Heat production determinations in this record are derived from samples collected from within the Australian Antarctic Territory (AAT; Figure 1) which consists of all the islands and territory south of 60°S and between 45°E and 160°E, and for the purposes of this report, including Terre Adélie (Figure 2; French Territorial Claim; 136°E to 142°E).

The majority of heat production determinations in this report are derived from whole rock analyses sourced from the Geoscience Australia’s (GA) geochemical database (OZCHEM) which can be accessed at: https://www.ga.gov.au/products/servlet/controller?event=GEOCAT_DETAILS&catno=65464. Antarctic OZCHEM whole rock geochemical data is mostly from the 1970’s through to the early 1990’s when the then Bureau of Mineral Resources (BMR; now GA) conducted extensive field geological mapping operations in the AAT. The remainder of geochemical analyses are sourced from readily available published literature (mostly from recent research studies) and a small amount

of unpublished data. The reader should note that the geochemical analyses complied for this report is not considered by the authors to be exhaustive. The reader should also note that analytical techniques for the determination of U, Th and K2O may vary according to techniques available to the researchers and the accuracy and precision will vary accordingly. No effort is made here to fully assess the data and the values are taken at face value. The reader should consult the relevant references and data sources for a full discussion on the methods, detection limits and uncertainties used to acquire the U, Th and K2O concentrations. All complied data are presented in the appendix (Tables A2-A10) and divided into the following geographic regions (shown in Figure 2):

Blue shading represents the continental ice sheet, grey shading represents floating ice shelves. Detailed data tables are presented in the Appendix, however, summary tables (Table 1-10) provide a generalised overview of the compilation for each area, including maximum and minimum heat production and ‘average heat production’ and ‘median heat production’ values (values ≥1 μWm-3 are

5


rounded to one decimal place, where values <1 μWm-3 are rounded to two decimal places) The average heat production value is simply an arithmetic average of the available data and does not consider sampling biases during sample collection (e.g. many sampling regimes at the time of collection were based around geochemical studies specifically targeting volumetrically minor rocks, e.g. Proterozoic dolerite dykes) and therefore this value may not indicate a true representation of the bulk regional heat production average. The reader should also note that there are other potential sources of bias for heat production studies and these are outlined by Jaupart and Mareschal (2004). We also include the median value as this may provide a better estimate of the ‘central tendency’ of the data, rather than being influenced by uncharacteristically deviate outliers. GEOLOGY OF AUSTRALIAN ANTARCTIC TERRITORY (AAT)

A detailed description and synthesis of the basement geology of the Australian Antarctic Territory (AAT) is beyond the scope of this record and the reader is directed to the numerous references on the topic elsewhere, particularly the excellent syntheses by Tingey (1991), Fitzsimons (2000) and Boger (2011). The summary below is taken from these references. In general, the East Antarctic Shield is comprised of several Archean-Paleoproterozoic terrains, enveloped and, in part, reworked by extensive Proterozoic (~1700-900 Ma) high-grade metamorphic episodes and associated felsic plutonism. Some regions (e.g. southern Prydz Bay) are, in turn, reworked by Cambrian (~530-500 Ma) high-grade metamorphism and felsic plutonism, but in many areas Cambrian activity is limited to low-grade isotopic resetting and limited post-tectonic felsic pegmatite emplacement. Exposed Archean to earliest Paleoproterozoic nuclei include the Napier Complex (~3800-2500 Ma), located in Enderby Land at the western periphery of the AAT, the Vestfold Hills (~2500 Ma) located on the north-eastern shore of Prydz Bay, with relic fragments of extensively reworked Archean crust recognised along the Mawson Coast (where it is thought to represent the margins of the Archean Napier Complex) and fragments of crystalline Meso- to Neoarchean crust are also recognised in the southern Prince Charles Mountains (Ruker Terrane) and the Denman Glacier region. Late Meso- to Neoproterozoic (~1100-900 Ma) high-grade metamorphism (and associated intrusive activity) affected Kemp Land, exposures along the Mawson coast, parts of the Prince Charles Mountains, and coastal exposures along southern Prydz Bay. The eastern shore of Prydz Bay (except the Vestfold Hills) is extensively reworked by Cambrian (~530-500 Ma) high-grade tectono-metamorphism and intruded by associated felsic granites and pegmatites. Extensive Cambrian reworking is also identified at the Mawson Escarpment in the southern Prince Charles Mountains where it is thought to represent a major crustal suture (Boger et al., 2001). To the east (at ~100° E), the Bunger Hills is a large ice-free coastal region comprised of predominantly Paleo- to Mesoproterozoic high-grade rocks (Meso-archean protoliths are recognised in the Denman Glacier region immediately to the west of the Bunger Hills), intruded by several generations of Neoproterozoic dolerite dyke swarms (e.g. Sheraton et al., 1995), and subsequently affected by a high-grade regional metamorphic event at ~1200-1100 Ma. The region was intruded by Cambrian post-tectonic syenitic plutons, pegmatites and alkaline mafic dykes, particularly immediately west of the Denman Glacier. The George V Land, Terre Adélie and Victoria Land region, between longitudes 135-160º E, is very poorly exposed with minor bedrock outcrops limited to small peninsulas (<1 km2; e.g. Cape Denison and Cap Jules) and isolated inland nunataks (e.g. Aurora Peak). Terre Adélie and George V Land are comprised of earliest Paleoproterozoic igneous protoliths (~2440 Ma), intruded by Proterozoic (~1800 Ma) mafic dyke swarms (e.g. Sheraton et al., 1989; Carson, unpublished data), overlain by Proterozoic siliciclastic sediments and subsequently affected by low grade metamorphism ~1700 Ma (e.g. Ménot et al., 2007). The George V Land and Adélie region have long been correlated with similar rocks outcropping along the southern coastline of South Australia (e.g. Ménot et al., 2007 and many others). East of the Mertz Glacier (~144º E), Victoria Land is dominated by Cambrian metamorphism (locally termed the Ross Orogen) and associated felsic intrusive activity.

Crustal Heat Production

CRUSTAL HEAT PRODUCTION OF THE AUSTRALIAN ANTARCTIC TERRITORY

Rocks exposed across the Australian Antarctic Territory (AAT) exhibit a wide range of heat production values, similar to the range and magnitude of crustal heat production recognised worldwide (e.g. Jaupart and Mareschal, 2004), reflecting rock type and the superimposed effects of high-grade metamorphism (Tables 1-10; appendix Tables A2-A10). Generally, we note low (~<2 μWm-3) to moderate (~2-8 μWm-3) heat production of Archean and Proterozoic metamorphic terranes (respectively), where pre-existing lithologies have undergone at least one episode of high-grade metamorphism. Lithologies exhibiting ‘high’ (>8 μWm-3) to very high (>20 μWm-3) heat production values are generally felsic intrusives (i.e. granites) either as large plutons and small dykes or stocks. These are generally, but not exclusively, Cambrian in age. We will briefly describe the heat production characteristics from each region in order from west (Enderby Land) to east (Terre Adélie, George V Land and Victoria Land) as listed earlier. Enderby Land Enderby Land (Figure 2) encompasses the Archean Napier Complex (~3800-2500 Ma) ultrahigh temperature metamorphic terrane and the adjacent high-grade Proterozoic Rayner metamorphic Complex (~1100-900 Ma; Tingey, 1991) to the south. Two hundred and twenty heat production determinations were calculated from across the region, the results are summarised in Table 1 (see appendix for full dataset Table A2), and illustrated in Figure 3. Heat production from Enderby Land varies from a maximum of 19.5 μWm-3 to effectively zero. The average heat production from both Archean rocks (174 samples) is ~1.7 μWm-3 (median ~0.8 μWm-3) and all Proterozoic rocks (46 samples) is ~2.3 μWm-3 (median 0.8 μWm-3). There is little difference in heat production with respect to assumed geological age, with the general spread of heat production values from both Archean and Proterozoic samples very similar (Figure 3). Granites (both Proterozoic and Archean) have generally elevated heat production (average ~6 μWm-3; median ~4.8 μWm-3).

Kemp Land and Mawson Coast The Kemp Land and Mawson Coast regions are contiguous regions that lie broadly to the east of Enderby Land extending to Mawson Station and adjacent areas (Figure 2). Outcrops in this region are considered part of the high-grade Proterozoic Rayner metamorphic complex (~1100-900 Ma; Tingey, 1991). The average and median heat production values for all rock types and geological ages in this region are ~1.8 μWm-3 and 1.0 μWm-3 respectively (Table 2; see appendix for full dataset Table A3). Granites, granulites, gneisses and pelites all display considerable range in heat production, with elevated maximum values ~11.0, 6.5, 13.7 and 6.5 μWm-3 respectively (Table 2). All Archean samples have an average heat production of ~0.8 μWm-3 (median ~1.0 μWm-3) whereas all Proterozoic rocks have an average heat production of ~1.9 μWm-3 (median ~1.0 μWm-3) very similar to that noted from the Enderby Land region earlier (Figure 4).

Vestfold Hills and southern Prydz Bay The Vestfold Hills is a large ice-free region (~400 km2 in area) located on the eastern shore of Prydz Bay (Figures 2 and 6) and is comprised predominantly of Paleoproterozoic to Neoarchean metamorphosed felsic, mafic and ultramafic orthogneiss and paragneiss, spectacularly intruded by Neoproterozoic dolerite dyke swarms (e.g. Tingey 1991). A total of 113 heat production determinations were made, ranging from 6.2-0.02 μWm-3. Gneisses and granulites range from ~6.2-0.05 μWm-3 (median 0.4 μWm-3) and ~0.5-0.02 μWm-3 (median 0.2 μWm-3), respectively. Proterozoic camptonite (~dolerite) dykes range from 2.3-0.9 μWm-3. The overall average heat production for the Vestfold Hills is low, ~0.8 μWm-3, with a median value of 0.4 μWm-3 (Table 4).

The Prydz Bay coast here refers to the region along the eastern coastline of Prydz Bay south of the Vestfold Hills (south of the Sørsdal Glacier; Figure 6), and includes the Rauer Islands, Brattstrand Bluffs, Larsemann Hills, Bølingen Islands and other numerous small promontories, peninsulas and scattered offshore islands (Figure 6). Prydz Bay is broadly comprised of Proterozoic to Cambrian granulite-facies rocks (some Archean rocks are known to exist in the Rauer Islands but these are not specifically identified in the OZCHEM database) and Cambrian granites. A total of 166 heat production values were determined from Prydz Bay (Table 5, Figure 7; including the Larsemann Hills, which is also briefly discussed below). The heat productions range from 65.9-0.1 μWm-3 with an average value of 4.4 μWm-3 and a median of 2.3 μWm-3. Granites from Prydz Bay (all but one recorded as Cambrian, n = 26) are notable in that they have elevated heat production values with an average of 14.7 μWm-3 and a median of 12.0 μWm-3 and one extremely elevated value at ~65.9 μWm-3 due primarily to elevated Th contents (up to 878 ppm Th). The Larsemann Hills (an ice-free area of ~40 km2 in southern Prydz Bay; Figure 6) is notable for Cambrian granites (e.g. the Progress Granite) with elevated heat production values between ~10-66 μWm-3 (Figure 8). The remainder of the rock types represented in samples from the Larsemann Hills are somewhat lower although can still be considered to be elevated with the average and median heat production values of 5.6 μWm-3 and 2.5 μWm-3 respectively. See appendix Table A5 (Vestfold Hills) and Table A6 (Prydz Bay) for the full dataset.

11


In summary, along the Prydz Bay coast line, the geology of the Vestfold Hills is characterised by low heat production with a median value of ~0.4 μWm-3; Proterozoic rocks from southern Prydz Bay are characterised by moderate heat production values of ~2.1 μWm-3 (median) whereas Cambrian granites are typically elevated in heat production with a median value of ~13.1 μWm-3.

Prince Charles Mountains The northern Prince Charles Mountains (nPCM; Figure 2) are an area of isolated nunataks located some 300 km inland from Mawson Station on the western flanks of the Amery Ice Shelf/Lambert Glacier. The nPCM are mostly comprised of Mesoproterozoic (~1400-1000 Ma) low- to high-grade metamorphic rocks (e.g. Tingey, 1991; Mikhalsky et al., 2001). Heat production determinations (Figure 9) were calculated from 368 samples with a maximum value of ~39.3 μWm-3 from a (probable) Proterozoic granite. In general, as has been shown elsewhere, Proterozoic rocks display moderate to low heat production (average 2.2 μWm-3, median 1.1 μWm-3) whereas Cambrian (including post-Cambrian and other assigned Phanerozoic intrusives) are somewhat higher with an average heat production of ~7.5 μWm-3 (median 6.4 μWm-3). Table 6 shows a summary of the major rock types represented in the region (several minor rock units are not represented for clarity; see Appendix Table A7 for full dataset).

The southern Prince Charles Mountains (sPCM; including the Mawson Escarpment) lie to the south of the nPCM and consist of mostly isolated massifs, nunataks and exposed ridges. The sPCM are mostly comprised of crystalline Archean rocks overlain by Proterozoic low- to high-grade metamorphosed sediments and intruded by Proterozoic dolerite dykes and Cambrian granites (e.g. Tingey, 1991; Mikhalsky et al., 2001; Boger, 2011). A total of 147 heat production determinations were conducted on rocks from the sPCM (Figure 10; Table 7; Appendix Table A8), with a maximum of ~10 μWm-3 (Cambrian granite) and an average value of 2.0 μWm-3 (median 1.5 μWm-3). There appears to be no strong correlation between Heat Production and the inferred age of the rock units (Figure 10), though Proterozoic heat production has a lower average value of 1.5 μWm-3 (median 0.6 μWm-3) compared with that of Cambrian intrusives (3.8 μWm-3 and 2.2 μWm-3 respectively; Table 7) and Archean rocks (2.5 μWm-3 and 2.1 μWm-3 respectively).

Bunger Hills and Denman Glacier region The Bunger Hills-Denman Glacier area (e.g. Sheraton et al., 1995) comprises the large ice-free area (~300 km2) of the Bunger Hills and the Obruchev Hills to the east of the Denman Glacier (collectively the Bunger Hills) and the scattered small outcrops immediately to the west of the Denman Glacier (collectively for the purposes of this record the ‘Denman Glacier region’). This region is comprised of Archean to Proterozoic metamorphic rocks intruded by Proterozoic dolerite dyke swarms and Cambrian syenites and granites (Sheraton et al., 1995). One hundred and ninety-nine heat production values were determined from the Bunger Hills (Figure 11; Table 8; Appendix Table A9) whereas 25 were determined from the area west of the Denman Glacier. The majority of values from Proterozoic rocks were low, generally less than 2.5 μWm-3 (Proterozoic rocks heat production average ~0.8 μWm-3 with a median value ~0.5 μWm-3; Table 8), however (as is observed from Prydz Bay) Cambrian intrusives, with elevated HPEs (trachyandesite, trachybasalt and trachyte) also displayed markedly elevated heat production values from as much as ~31.0 μWm-3 to 5.6 μWm-3 with an average and median heat production of 10.7 μWm-3and ~7.9 μWm-3 respectively. The heat production values to the west of the Denman Glacier (Table 9) also exhibit the same dichotomy; Proterozoic rocks have generally low heat production (average ca.1.4 μWm-3; median ~0.8 μWm-3) whereas Cambrian intrusives have somewhat higher heat production values of ~4.4 μWm-3 on average (4.2 μWm-3 median).

Terre Adélie, George V Land and Victoria Land The last region to be covered, collectively, is the Terre Adélie, George V and Victoria lands (TAGVVL) for which there are few data, due to limited outcrop, particularly in the Terre Adélie and George V Land region. This entire region represents the swath of coastline from around 120-160º E longitude and south along the western edge of the Trans-Antarctic Mountains (Figure 2). The area is comprised of Paleoproterozoic crystalline basement, Proterozoic and Cambro-Ordovician metamorphosed sediments and intrusives (e.g. Ménot et al., 2007). Eighty-nine Heat Production determinations were conducted on rocks from the TAGVVL (Table 10; Appendix Table A10) with maximum and minimum Heat Production values of 6.7 μWm-3 and 0.1 μWm-3 respectively. Generally, Cambrian rock units have slightly higher, and more heterogeneous, heat production values than Proterozoic rocks although not markedly so (Figure 12). Interestingly, Proterozoic (~1600-1590 Ma) felsic volcanics sampled from moraine (Peucat et al., 2002) from the Terre Adélie coastline are slightly elevated in heat production (~2.7 μWm-3), and are similar in age, petrology and chemical composition to that of the Gawler Range Volcanics of the Gawler Craton in South Australia (Peucat et al., 2002). Cambrian rocks, which are exposed east of the Mertz Glacier, have average and median heat production values of 2.4 μWm-3 and 2.1 μWm-3 respectively, with Proterozoic rocks slightly lower at 1.50 μWm-3 and 0.8 μWm-3 respectively.

Summary

The compilation of ~1500 heat production determinations from the AAT presented in this report provides earth scientists with the first crustal heat production assessment across much of the exposed bedrock of East Antarctica. Crustal heat production values across the AAT show a wide range from negligible to as much as 65 μWm-3. Generally, Cambrian felsic intrusives generate higher heat production, with intermediate values from Proterozoic intrusives and metasediments (2-8 μWm-3), and low values (<2 μWm-3) from Archean rocks. A good illustration of the correlation of geological age with heat production is from Prydz Bay, where the Neoarchean-Paleoproterozic metamorphic terrain (~2500 Ma) of the Vestfold Hills exhibits uniformly low heat production (with an average heat production value of ~0.8 μWm-3), the Proterozoic (~1100-1000 Ma) metasediments and pre-tectonic intrusives along the eastern Prydz Bay coast south of the Vestfold Hills have typically intermediate values (average heat production value of ~2.6 μWm-3), and the Cambrian intrusives (in particular from southern Prydz Bay) have elevated values with an average ~15 μWm-3. We anticipate that this simple compilation of heat production may form a basis for future, more comprehensive, studies investigating the thermal structure of the East Antarctic crust and facilitate more robust estimates of heat flow in the Antarctic continent, a critical yet poorly understood, boundary parameter controlling the behaviour of the vast Antarctic ice sheet.

Appendix A: Data tables

The column headings for the data compilations presented in the Appendix from each area are described in the following order: SAMPLEID is the GA reference number for the sample (in the case of non-GA samples the sample number used is that which appears in the independent published literature). This column represents the published sample number provided in the relevant reference. DESCRIPTION is a brief summary of the rock type and minerals present (abbreviations listed in Table A1). LITHNAME is a general rock classification based on the information contained within OZCHEM or from the referenced literature (the description is taken as face value and no effort is undertake to critically assess the lithology type and is used in the discussion below with no modification). AGE is the generalised geological age of the sample, estimated where unknown, otherwise based on available geochronology. GEOGRAPHIC AREA refers to the broad region from which the sample is derived LOCATION DESCRIPTION is a more detailed description of the location relative to local geographic features (see Australian Antarctic Gazetteer at http://data.aad.gov.au/aadc/gaz/index.cfm). LATITUDE and LONGITUDE are derived from the Geoscience Australia OZROCKS database (for OZCHEM samples), for which the map datum is unrecorded. We assume WGS84 acknowledging that there will be some several hundred metres uncertainty in the location of some samples depending on what datum was originally used for field mapping in the 1970-80’s, which should be sufficient for the reconnaissance nature of this record. U (ppm), Th (ppm) and K2O (wt%) columns are self explanatory; the reader is referred to Sheraton (1981, 1985) for a description of analytical methods and detection limits employed by the GA geochemistry laboratories at the time of sample analysis for GA samples. The reader is referred to individual journal publications for analytical methods employed by other institutions (see full data tables in the appendix for references for the tabulated data). Heat Production (μWm-3) is the heat production generated from the radioactive decay of radioisotopes of U, Th and K as per equation (1). The final column (Reference) is the source of the geochemical data use for the determination of heat production.
