    9 Louisburg 10 Freeman 11 Lane 12 Osawatomie 13 Fontana 14 New Lancaster 15 Drexel In 2002, the Kansas Departm ent of Transportation (KDOT) began a project with the Kansas Geological S urvey (KGS) to investigate the construction aggregate properties of lim estones of the Pennsylvanian Kansas City Group in Miam i County. That project involved drillcore donations with over 2,700 linear feet of core now housed at the KGS. That older project docum ented engineering properties of drillcore samples, but improved stratigraphic correlations were needed. The KGS is subcontracting with form er KGS postdoctoral researcher Dr. Bradley Cram er of the University of Iowa to refine stratigraphic interpretations of Pennsylvanian bedrock units in Miam i County. The work perform ed under the subcontract includes description and analysis of a series of 33 drill cores from throughout Miam i County (see Table 1 and labels on index m ap). Descriptions of the cores include detailed cm -scale core logging and the production of high-resolution stratigraphic columns for each core. Analysis of the core suite will eventually include two prim ary data sets: carbon isotope chem ostratigraphy and m icropaleontological biostratigraphy using conodonts. These two data sets will be com bined as bio-chem ostratigraphy and integrated into a comprehensive synthesis of the chronostratigraphic correlation of the units contained within the cores. This synthesis will directly inform the surficial m apping and geospatial understanding of both the surface and shallow subsurface geology of Miam i County.

    Quaternary System Undifferen tiated Alluvium — Undifferentiated alluvium that typically is less than 4,000 years old comprises valley fills beneath the m odern floodplain of the Marais des Cygnes R iver and its tributaries. This alluvium consists of clay, silt, sand, and gravel, with the coarsest sedim ents comprising the lower 3-6 ft (0.9-1.8 m) of the valley fills. The fine-grained floodplain facies are m ostly dark gray, gray, dark grayish brown, and grayish brown silty clay, and silty clay loam. These deposits can reach thick nesses greater than 50 ft (15 m) in the Marais des Cygnes R iver valley. Alluvial Terraces — Alluvium that typically is 4,000 to 11,000 years old comprises valley fills beneath a low terrace (T-1) of the Marais des Cygnes R iver and its tributaries. This alluvium consists of clay, silt, sand, and gravel, with the coarsest sedim ents comprising the lower 3-6 ft (0.9-1.8 m) of the terrace fills. The fine-grained alluvium is m ostly brown, dark yellow ish brown, and yellow ish brown silty clay loam. These deposits can reach thick nesses greater than 70 ft (21 m) in the Marais des Cygnes R iver valley. Quaternary and Neo gene Alluvium — Clayey alluvium often interbedded with cherty gravel is com m on beneath high terraces and on hilltops in Miam i County. The num erical age of these alluvial deposits is unknown. However, based on their position in the landscape, the deposits on the hilltops probably aggraded during the Neogene (Aber, 1998), and it is lik ely that the high-terrace fills date at least to the m iddle Pleistocene. The lower 3-6 ft (0.9-1.8 m) of the terrace fills and hilltop deposits consist of cherty gravel. The overlying fine-grained alluvium m ostly consists of dark gray, gray, dark grayish brown, and pale brown silty clay. The distribution of fine-grained alluvium interbedded with cherty alluvial gravels is indicated by the Kenom a soil series, as shown on the Soil Survey of Linn and Miami Counties, Kansas (Penner, 1981). R edoxim orphic features, including strong brown and reddish brown m ottles and iron and m anganese oxide concretions, are com m on in the upper 3-10 ft (0.9-3 m) of the fine-grained alluvium. Alluvial deposits comprising the fills of high terraces are typically 20-30 ft (6-9 m) thick , but the alluvial deposits on hilltops generally are less than 15 ft (4.5 m) thick . A veneer of loess that is less than 3 ft (0.9 m) thick often caps the high-terrace and hilltop alluvial deposits. Co lluvial Ap ro n and Alluvial Fan Dep o sits — Deposits of clay, silt, sand, and gravel occur on footslopes and toeslopes in valley landscapes. These deposits m ostly accum ulated during the early and m iddle Holocene, although som e m ay date back to the term inal Pleistocene, and they comprise both colluvial aprons and alluvial fans. The colluvial aprons consist of m assive deposits of poorly sorted sedim ents that include m any angular, bedrock-derived pebbles and cobbles. The alluvial fans form ed where sm all, interm ittent stream s enter the Marais des Cygnes R iver valley and the valleys of its m ajor tributaries. The fan deposits are stratified and consist of well-sorted alluvium dom inated by brown, dark yellow ish brown, and yellow ish brown silty clay, silty clay loam, and silt loam. Thin lenses of gravel are com m on, and buried soils often occur at the top of upward-fining sequences. PALEOZ OIC

    Carbo n ifero us System –Pen n sylvanian Subsystem (descriptions from Miller, 1966) Lan sing Gro up Plattsburg Limesto n e/Vilas Shale — The lower part of the L ansing group is composed of the Plattsburg L im estone and overlying V ilas S hale (~35 ft; 11 m thick ). The Plattsburg Limesto n e (~16 ft; 5 m) is composed of two lim estone m em bers and intervening shale m em ber. In ascending order, these units are Merriam lim estone, Hick ory Creek shale, and Spring Hill lim estone. The Merriam Limesto n e Member, averaging 3.5 ft (1 m), but ranging from 1- 9.5 ft (0.3-3 m), is com m only a single, m assive bed of bluish-gray to light-gray, fine-grained, dense lim estone. The lower part (3.6 ft; 1.1 m) of the Merriam lim estone is a m assive, bluish-gray to light-gray, cross-bedded, oolitic lim estone, locally with black , fossiliferous chert. It is com m only a resistant unit, form ing scarps and outcrops. Coated grains and Osagia-lik e form s are usually present and in som e places these constitute a large part of the lim estone. Myalinid pelecypods and productid brachiopods can be com m on. The upper part of the Merriam lim estone is a light- to m edium-gray, fine-grained, m assive, locally cherty lim estone, but usually not fossiliferous. "W orm tubes" are present in som e localities on the upper surface. The Hicko ry Creek Shale Member (locally absent to 2 ft;0.6 m) is yellow ish-gray to orangish-gray, clayey, nodular, and calcareous. A thin, nodular lim estone bed locally occurs near the m iddle of the unit. The shale is fossiliferous, com m only with crinoid rem ains and bryozoans. The Sp ring Hill Limesto n e Member (4-17 ft; 1.2-5 m) is light olive-gray to yellow ish-gray, fine- to coarse-grained, thin- to m edium-bedded, and sandy. It contains chert locally and m ay be oolitic in places at its top or conglom eratic with lim onite pebbles, shale and ironstone fragm ents, and sm all abraded calcite crystals. S hale partings and thin, wavy carbonaceous streak s m ay be present within this m em ber. Triticites sp. and Osagia-lik e form s and echinoid spines are locally abundant. A zone of large Composita sp. is com m only found near the base of the unit. The Vilas Shale (5 ft; 1.5 m, thick ening westward to 30 ft; 9 m) is grayish-olive to light-gray, sandy, and block y. In the western part of the county it contains a considerable am ount of m oderate yellow ish-brown siltstone and orangish-gray cross-bedded sandstone, which m ay be up to 4 ft (1.2 m) thick . Plant rem ains are com m on in the sandy layers, but otherwise it is relatively unfossiliferous. Kan sas City Gro up Wyando tte Limesto n e/Bo n n er Sp rings Shale — The upperm ost part of the Kansas City Group is composed of the Wyando tte Limesto n e and the overlying Bonner Springs S hale. The W yandotte L im estone is composed of five alternating shale and lim estone m em bers. From the base upward, these five units are the Frisbie lim estone, Quindaro shale, Argentine lim estone, Island Creek shale, and Farley lim estone. The W yandotte is a cuesta-form ing form ation, ranging in thick ness from about 10 to 80 ft (3 to 24 m). The shale m em bers are present only locally in Miam i County. The absence of the shale m em bers and the sim ilarity in the lithology of the two upper lim estone m em bers m ak es identification of the units difficult. The Frisbie Limesto n e Member (2.5-3.6 ft; 0.8-1.1 m) is a light olive-gray to light brownish-gray, fine-grained, m assive lim estone. L ocally, thin shales (
