During the course of prospecting, an area of about 70 hectares has been
demarcated /mapped over cadastral map on scale 1:4000, with the objective to
demarcate limestone bearing areas on Khasra map and after deducting restricted area,
an area of about 47.63 hectare of village Kosdana,Tehsil Gandhwani have been
delineated as available mineralized area. Prospected area is confined to private as well
as government revenue land. Private land is under cultivation. For auction an area of
47.63 hectares is being proposed, including 47.63 hectare mineralized and 21.618
hectares as ancillary area. During the period under report total 184.50 meter drilling
has been carried out by putting 09 no. of boreholes not at regular grid interval, but try
to maintain distance of 200 meter between the two successive boreholes and reveals
that the average thickness of limestone is 13.10 meter with very thin, averaged 0.51
meter over burden of black cotton soil, weathered rocks and sandy soil. A sum total of
71 no. of core samples have been collected and sent for chemical analysis at
departmental laboratory Jabalpur without any cross check analysis. Analysis results
reveal that the limestone is suitable for cement industry. The present investigation,
comes within general exploration stage (G 2), hence the estimated resource of the
order of 15.28 million tones, by area of influence method, classified as indicated
resource with UNFC code of 332.

13.10 meter, without any intercalation of other litho units. Looking to the CaO
content, in association with other essential elements the aforesaid deposits of
limestone can be utilized in manufacturing of cement.
CHAPTER � I
INTRODUCTION
In pursuance of the field program of the Directorate of Geology &
Mining Madhya Pradesh for the field season 2017-18, co-authors of this
report carried out prospecting of Bagh limestone in the Cretaceous
marine sediments of Bagh basin, in parts Kosdana village of Gandhwani
tehsil of Dhar district of Madhya Pradesh, in accordance with the
MINERAL AUCTION RULES 2015 and MINERAL EVIDENCE RULES 2015.
Proposed limestone block for auction, having 47.63 hectares, without
ancillary area
Limestone and other carbonate rocks are extremely valuable raw
materials and are widely used throughout industry, although the
Construction and cement manufacturing industries are generally the
principal consumers.
Limestone is a sedimentary rock composed mainly of calcium
carbonate (CaCo3), occurring as calcite or occasionally aragonite in
recent deposits. Around 20% of all sedimentary rocks are limestone or
dolomite or gradations between the two. Common impurities in
sedimentary carbonate rocks include clay minerals, silica (clastic
material and/or chert), organic matter and iron hydroxide minerals.
Other sedimentary carbonate rocks include marl, travertine and vein
clay and limestone. Travertine is formed by rapid precipitation of
calcium carbonate around hot springs. It is deposited in compact,
fibrous or concentric layers producing a banded appearance. The softer
and more porous form of travertine is known as calcareous tuff.
District Dhar is endowed with huge resources of limestone,
belonging to Bagh group of rocks. Promising limestone bearing area,
comprising part of village Kosdana of Gandhwani tehsil had been
demarcated for further G-2 level prospecting by means of drilling.
Though the limestone is of good quality, and major portion of proposed
block occupies in government agriculture land.

1.1 Location and Accessibility:
The area under report falls within the Survey of India
Toposheet No.46 J/15 and comes under the Kosdana revenue village of
Gandhwani Tehsil of Dhar district, Madhya Pradesh.The nearest
railhead is Indore. Other main towns, like Manawar and Gandhwani, are
situated at a distance of about 32 Km and 10km respectively, from the
proposed block and well connected by National highways No.3 and 59
respectively from Indore. The nearest railheads Mhow and Indore are
situated at a distance of 55 km. and 90 km. respectively from district
headquarter Dhar (PLATE-1).
1.2 Physiography and Drainage:
The Bagh bed exposures form flat topped plateaus of
elevations ranging from 220 metres to 260 meters. This is due to
horizontal to very low dips of Bagh beds, hardly exceeding 05°. The
area is gently undulating, the mean minimum elevation is 255.0 metres
and the highest elevation is 327.0 mtr (about 4 km.North of block in
Khojakuan village). The general country slope is to the south. The flat-
topped hills comprising of basaltic flows rise to a height of 15 mtr to 50
mtr, from the ground level. Bagh limestone occurs as scattered mounds
with flat-topped surfaces. The limestone bearing mounds have a
general height between 5 mtr to 10 mtr. Valley portions in the area
consist of Archaean rocks and Nimar sandstone. Prominent river Uri
drain the area running almost north-south and ultimately joins the
Narmada River at Koteshwar.
1.3 Climate:
The climate of the area is moderate. April to June is the
period of summer with temperature reaching upto 44°C at places.
Manawar, Gandhwani and Kushi Tehsils are comparatively hot then
other tehsils of dhar district. Rainfall is moderate in the area and it is
mostly due to the south westerly monsoon. The south-west Mansoon
following the summer lasts till September or early weeks of October.
2
Rainfall in the area ranges from 80 cms. to 90 cms. The winters are
moderate and dry.
1.4 FLORA AND FAUNA :
Black cotton soil supports thick forest growth. The main
tree types are teak, Dhaora, Anjan and sal etc.The main crops of the
area is wheat,maize, Juwar, Bajra, Gram, Sugarcane, cotton,
Groundnut and pulses etc.The area has at present few resources
forests where �teak�, �sal�, �mahuwa� grow scantily along with shrubs
constituted by �Amla�, �Korandi�, etc. Otherwise, the area is practically
barren due to intensive cutting of wood for fuel/timber purposes
without any substantial new plantation. Though at places, Forest
Department of Madhya Pradesh Government is trying to make up the
loss of vegetation by afforestation as witnessed around Balwari. Fauna
is almost restricted to domestic animals due to virtual destruction of
forest.
1.5 INHABITANTS:
The important tribes of the area are Bhil and Bhilala and
they are mostly dependent on agriculture and manual labors.
1.6 PREVIOUS WORK
The earliest account of the geology of the Bagh beds was
given by Blanford (1869). Later on Vredenberg (1907), Bose (1984)
and Gupta & Mukherjee (1938) have substantially contributed to the
geology of Bagh beds and associated rocks of the area. These
pioneering efforts have been compiled by Pascoe (1959). The Bagh
sediments have been described by Blanford and Vredenberg as marine
equivalent of the fresh water beds known as Lametas, but Bose has
suggested that these sediments have been overlain unconformably by
Lametas. Bose has further classified the Bagh beds into 4 groups viz.
(a) Oyster beds, (b) Nodular limestone. (c) Deola and Chirakhan marl
and (d) Coralline limestone in ascending order. These overlie the
sandstones named as Nimar sandstone � with or without unconformity
and according to Bose it is of fresh water nature and is generally older
3
to both Bagh and Lameta beds. Although there are some
palaeontological evidences that Nimar sandstone can be grouped along
with Bagh beds (Vredenberg, 1869). Palaeontological evidence shows
that Bagh fauna shows relationship with Cretaceous faunas of Europe
and a close affinity with a small fauna found in southwest coast of
Arabia and stratigraphically is confined between basal Cenomanian to
Turonian.
During recent times, many workers have restudied the
Bagh beds of the area as a part of systematic geological mapping
programme of Geological Survey of India viz. Neelkantam (1967),
Mahendra Singh (1965), Munshi & Khan (1973), Munshi (1972),
Sonakia & Nair (1976), Nair & Choubey (1977) and Nair & Choubey
(1978).All of these workers include the sandstone in the basal portion
of the Bagh and consider the limestone (nodular & coralline) with marl
to constitute the upper part of the Bagh beds. Dr.N.H Vaghmarey
&Pradeep Bhuriya carried out prospecting to carve out cement grade
limestone block in Sitapuri-Deora-Udiyapura villages in Manawar tehsil
and proposed a block of 344 hectare for auction.

CHAPTER � II
GEOLOGY
2.1 REGIONAL GEOLOGY :
Archaean rocks form basement over which unconformably
overlie the bagh and the Lemata sediments covered by Deccan Trap
flows and basic intrusions. The general stratigraphic succession in the
area is as below :
Recent Soil
Deccan Trap Basaltic lava-flows and basic intrusions.
---------- Unconformity---------
Lameta Quartzitic sandstone
Coralline limestone
Bagh Beds Marl
Nodular limestone
Nimar sandstone
---------- Unconformity---------
Archaeans Granites, granitic-gneisses, phyllites,
schistose rocks etc. with crystalline
limestone, quartz and pegmatite veins.
Archaeans :
Archaeans rocks form the basement and oldest rocks in the
area which are overlain by Bagh and Lameta sediments. The Archaean
members are best exposed in river section of man, sukkar etc. East of
Zirabad, around Attarsumba and in the nala section south of Jhiran,
large outcrops of Archaean rocks has been recorded. The Archaean
rocks consist of granites, granitic gneisses, phyllites, chlorite and/or
hornblende schist�s, bands of crystalline limestone along with pegmatite
and quartz veins.
The granite rocks have been greatly weathered and are
represented in the area mostly as huge boulders and fragments
composed essentially of quartz, pink-to-grey feldspar in the siliceous
matrix. Chlorite and/or hornblende are the common accessory mineral.
Along with granites, highly metamorphosed rocks, i.e.,
granite- gneisses and mica schists are well exposed. Granite-gneisses
show long alternate bands of granular (quartz-feldspar) and schistose
5
minerals (chlorite, hornblende etc.). They are hard, compact, well
jointed, and smooth and polished due to river water action. The rocks
are, steeply dipping and at many places folded.
Phyllites and schistose rocks, both chlorite and hornblende
schist, in the area are highly weathered, folded and intruded by quartz
veins.South east of Zirabad, near Attarsumba and Karondiya, bands of
crystalline limestone trending NW-SE and dipping from 700 to nearly
vertical have been recorded.
The crystalline limestone is dirty-white to yellowish and
show concentric layers of anhedral calcite which are coarse in the
central portion and thin out towards the periphery. The limestone is
associated with the irregular mass of brown chert and quartz fillings.
Bagh Beds :
Nimar Sandstone :
Nimar sandstone is the oldest member of the bagh group.
The sandstone rests unconfomably over the Archaean metamorphic and
is overlain by calcareous rocks.
Nimar sandstone is well exposed at the junction of rivers
man and sukkar. The sandstone exposures are noticed in the valley
portions and at gentle mounds in the region near attarsumba, ghursal,
Bariya, in the river bed of Sukkar, on Zirabad-Manawar road and
further west in the river Sukkar, south-east and north-west of the Dhar
cement plant etc.
The exposed thickness of the Nimar sandstone varies from
0.5 mtr to 6 mtr. The sandstone is conglomeratic at the base,
succeeded by grity sandstone. At places it is interbeded with pink
shale. The Nimar conglomerate consists of fragments of quartz, jasper
etc., of varying degree of coarseness and roundness and are embedded
in a siliceous to ferruginous matrix. The sandstones range from coarse,
gritty to fine-grained rock of varying hardness and in different shades
of red, pink purple, white etc. and are calcareous at places. Primary
sedimentary structures mainly gradded bedding and current bedding is
observed frequently in the sandstone unit.
In a well, south-east of the Dhar Cement Factory and in the
road cutting Zirabad-Manawar road near Ratitalai, characteristic
reddish, pinkish shaley horizons occur interbedded with the Nimar
sandstone. In the area under study, the arenaceous facies (Nimar
sediments) is overlain by the Bagh limestone.
6
The limestone occurs mostly along gentally slopping ridges
and flat-topped mounds. The limestone beds are soft therefore their
preservation is mostly due to the protective covering of the deccan trap
flows.
A revised classification of Bagh beds as proposed by sahni
and jain (1968) is as follows :
Marine 1. Coralline limestone
2. Nodular limestone with 1 to 5 ft. oyster bed at the
Base. Fresh Water Nimar Sandstone.
In the area surveyed, limestone is the only mineral of
economic interest. Deposition of Bagh limestone is observed in several
localities e.g. Zirabad, Ghursal, Attarsumba, Karondiya, Bariya, Soyala,
Sitapuri, Phutibawri, Chirakhan, Jhiran, Kachhauwada, Borghata,
Chakrud etc.
Nodular-Argillaceous limestone:
In general, the nodular limestone directly overlies the
Nimar sandstone and is most extensively developed. At places such as
in the man river section, it rests directly on the Archaean
metamorphics.
Nodular limestone is remarkably typical. At surface and
near its contact with the overlying coralline limestone it shows
characteristic nodular appearance. Near Kachhauwada, Attarsumba,
Karondiya, Nimtoka etc., the peculiar nodular character is lacking and
thick argillaceous limestone bands/blocks are exposed. According to
Bose (1884) �On the whole, however the name seemed to me the best
that could be given.�
The nodules in the limestone are irregular, varying from 3
cms. to about 30 cms. and are whitish, greyish to pinkish, inter mixed
with calcareous clay. At places small, thin veinlets of calcite are also
seen in the nodular limestone. Average thickness of this unit is about 5
mtr but beds as thick as 10 to 15 mtr have also been recorded.
Marl :
Marl a fine-grained, silty, calcareous rock has been
recorded between the nodular and coralline limestone units. In the
area, marl is best developed in the neighbourhood of Deola and
chirakhan known as �Deola-Chirakhan marl�.
7
The marl is very soft almost flaggy type with varying
shades of yellow, red, green and purple. Average thickness of marl is
about 2 mtr. The marl bed is rich in marine Cretaceous fossils of
Echinoids, Brachiopods, Lamellibranchs and cephalopods etc.
Coralline Limestone:
It is the upper most unit of the Bagh sediments, exposed
widely in the surveyed area. This unit is so is named because of the
presence of fragments of corals in the rock. The limestone is
whitish-yellow, red, and pink and at places green, consists mainly
remains and broken fragments of Bryozoa shells and corals. At many
places the beds are laminated and well jointed. The average exposed
thickness of this unit is about 3 mtr.
Lameta :
In the area, the Bagh limestone are overlain by the Deccan
Trap flows but 500 mtr north of chakrud and 1 km east of Awral, the
nodular and coralline limestone are overlain by lameta sandstone. The
sandstone is quartzitic, hard, and compact and medium-to-fine grained
with shades of white, pink and purple.
Deccan Trap:
In the area under reappraisal several detached patches of
basaltic lava-flows have been recorded. The basalts overlie
unconformably the limestone of Bagh group and at places the Lameta
sediments. Around Zirabad, west of Ghursal, west of Ratitalai, south-
eastern and further south towards Awalda from Bariya, on the ridges
are covered by the Deccan Trap flows. The thickness of basaltic flows
varies from 5 mtr to more than 20 meter. There flows are different in
lithology, grain size and other characters and show well marked
spheroidal weathering. Conical shape is the typical geomorphic feature
of the lava covered hillocks. On either side of the �Dhar cement Works,�
east-west trending dolerite nearly 1 km long and 1 to 5 mtr wide are
seen. A dolerite dyke of 5 to 6 mtr width have also been observed
between attarsumba and karondiya. On the top, these dykes are very
narrow but attain considerable width towards river man and further
east.
Recent :
Recent formation consists of alluvium and black cotton soil
whereas in some areas, red soil and yellowish calcareous soil and
yellowish calcareous soil is also present.
8
2.2 MODE OF OCCURRENCES:
The Bagh limestone is deposited in bedded form having
horizontal disposition and exposed on the surface, either in the form of
mounds or low lying ridges.
2.3 STRUCTURE:
The Bagh beds are tectonically undisturbed, which is clearly
evident by horizontal dip of the litho-units in the area and visible in
river section,just east of proposed block. Only at some places dip of the
beds are recorded up to 8° to 10°, and appears to be because of
undulations / depressions within the Archaean basement, which has
given a local tilt to these beds. Among primary sedimentary structures
current bedding and ripple marks observed at some places especially
within Nimar sandstone.

CHAPTER � III
DETAILS OF WORK DONE
3.1 RECONNAISSANCE GEOLOGICAL SURVEY
During the course of prospecting (field season2017-18), an
area of about 50.00 km2 had been rechecked / reconnoitered on scale
1:50000, with the objective to get acquainted with the geology of the
area and to locate new limestone bearing areas. Study area bounded
between latitude N 22020�00�: 22030�00� and longitude E 75052�30�:
75057�30� and comes under toposheet no. 46J/15. Reconnaissance
geological mapping has revealed that the rocks of Archean, Bagh
Group, Lameta Group and Deccan Trap are exposed in the area. The
present investigation is concerned with the Bagh Group of sediments.
The rocks of the Bagh group unconformably overlie the Archean rocks
and occur as discontinuous outcrops. These are mainly exposed around
in the central part of Toposheet 46 J/15 around Khojakuan,dedli
B,Ajantar etc. Bagh beds are more or less horizontally disposed and
comprise of three units lower Nimar Sandstone/red shale, middle
Nodular Limestone and upper Coralline Limestone. Deola Marl bed
exposed in Sitapuri and Chirkhan is considered as lower part of
Coralline Limestone. Thickness of Bagh beds varies from few meters to
20 m. Coralline Limestone and Upper Nodular horizons are highly
fossiliferous.
Coralline Limestone generally occurs as a capping over the
Nodular Limestone. Coralline Limestone is hard, compact and yellowish
brown to reddish brown in colour. It exhibits beautiful current bedding.
The upper part of the limestone has been silicified at places probably
due to the thermal effect of an overlying basaltic flow. Its thickness
varies from 1 m. to 5 m. This unit is highly fossiliferous. Coralline
limestone is underlain by Nodular limestone is well developed in the
proposed block. It is light grey to dark grey, fine grained and
argillaceous in nature. Its thickness varies from 1 m. to 8 m. On
10
weathering it breaks into nodules ranging in size from a few
centimeters to 30 cm. Upper most part of the Nodular Limestone
changes locally to marl bed designated as Deola marl.
3.2 DEMARCATION/DETAIL GEOLOGICAL MAPPING:
During the period under report an area of about 70 hectares of village
Kosdana has been mapped/ demarcated over the cadastral map on
1:4000 scale, with the objective, to demarcate limestone bearing areas
on Khasra map. Most of the mapped area is covered by very thin cover
of soil and pebbles of basalt and private land is under cultivation.
Outcrops of coralline limestone are visible in the area. Limestone is
horizontally bedded and well jointed (PLATE NO.-3).A mining lease of
7.5 hectare is sanctioned to Shri Nilesh Upadhyay and duly demarcated
on khasra map.
3.3 DRILLING:
The results of survey and demarcation of limestone in the
area, leads to take up the prospecting of limestone in this block by
means of drilling within the boundaries of revenue village
Kosdana.During the period under report total 184.50 meter drilling has
been carried out by putting 09 boreholes not at regular grid interval,
but tries to maintain spacing of 200 meter between the two successive
boreholes, wherever possible. The exact location of the boreholes has
been plotted on the map, enclosed with this report (PLATE No.4).
Limestone is exposed on the surface and the maximum thickness rarely
exceeds 15 meters, therefore boreholes are shallow & vary in depth
from 14.50 meter to 24.50 meters (ANNEXURE- I).
3.4 Topographical Survey:
The topographical survey has been carried out by departmental
surveyor, with the help of theodolite and dumpy level to provide
borehole points for drilling and try to maintain 200 M interval between
the two successive borehole points. Reduced levels of each point have
been established and later on contour plan on 2 M interval and digital
11
elevation model has been prepared.It was not possible to drill
boreholes at regular grid interval. (PLATE NO.-5 & 6).
3.5 MINERALIZED AREA:
On the basis of detail mapping, an area of about 67 hectares, of
village Kosdana had been selected for drilling. After deducting the
19.06 hectares restricted area, rest 47.63 hectares is available for
grant of mining lease and designated as mineralized area (plate no.
7).The mineralized area belongs to village Kosdana. During the course
of prospecting, limestone is intersected in all the boreholes.
3.6 SAMPLING:
During the course of prospecting, 71 no. of core
samples have been collected and prepared by conning and quartering
method which finally crushed and passed through 100 mesh sieves,
and sent to departmental chemical laboratory Jabalpur for its chemical
analysis. To ascertain the authenticity of chemical analysis no check
analysis had been done. Weighted average percentage were computed
by multiplying the run of individual sample drawn from a borehole with
its respective oxide percentage and the sum of all such values obtained
as above is divided by the total run.
Weighted average (CaO) =
Run of 1st sample* CaO % + Run of 2nd sample* CaO % + Run of 3rd
sample* CaO %............... total run of all samples
The chemical analysis results are tabulated with litho logs and
appended with the report as (annexure I,Table 2 to 10).
______o0o______

CHAPTER IV
CHEMICAL ANALYSIS AND RESOURCE ESTIMATION
The core obtained through drilling was studied and logging
was done (borehole logs appended as annexure-1, Table 2 to
10.Core samples were prepared as per their physical appearance and
similar runs in physical appearance were clubbed together to make one
sample. A sum total of 71 core samples, after proper preparation were
sent to departmental laboratory, Jabalpur for chemical analysis.
Coralline Limestone generally occurs as a capping over the Nodular
Limestone. Nodular limestone is light grey to dark grey to pink, fine
grained and argillaceous in nature. Its thickness varies from 3 m. to 8
m. On weathering it breaks into nodules ranging in size from a few
centimeters to 20 cm. Physically Coralline Limestone is hard, compact
and yellowish brown to reddish brown in color. It exhibits beautiful
current bedding. Its thickness varies from 1 m. to 5 m.
To ascertain the authenticity of chemical analysis no check
analysis had been done. Weighted average percentage were computed
by multiplying the run of individual sample drawn from a borehole with
its respective oxide percentage and the sum of all such values obtained
as above is divided by the total run.
Weighted average (CaO) =
Run of 1st sample* CaO % + Run of 2nd sample* CaO % + Run of 3rd
sample* CaO %............... total run of all samples
The chemical analysis results are tabulated with litho logs and
appended with the report.
Chemical analysis of the core samples obtained through
drilling revealed that, coralline limestone have comparatively high CaO
percentage than nodular limestone, but overall, there is no frequent
variation in chemical composition between the two and have average
CaO content is 48.57% and silica content below the tolerable limit with
13
an average of 7.50 %. The variations in chemical constituents in all the
boreholes are tabulated along with litho logs.
Resources are estimated by implying area of influence
method. In this method the area of influence of each borehole is
determined by putting the each borehole point in the center of polygon
(PLATE-8) and for computing resources, area of each polygon is
multiplied by the thickness of limestone in each borehole with the
specific gravity. The area of influence method is preferred because the
deposit is tabular body & there are about 09 no. of boreholes not
arranged in systematic grid pattern.
The total area of proposed block is 66.69 hectares including
47.63 hectares mineralized and 19.06 hectare restricted area. (PLATE-
9). Out of 09 boreholes drilled 08 are lying within the available area of
proposed block, whereas 01 borehole lying within the restricted area.
The present investigation, comes within general exploration
stage (G-2), hence the estimated resource of the order of 15.28 million
tones, classified as indicated resource with UNFC code of 332 having
average 48.57 % CaO have been estimated and tabulated in Table
No1.
Looking to the silica content in association with other
essential elements the aforesaid deposits of limestone can be utilized in
the manufacturing of cement.
14
CONCLUSION AND RECOMMENDATION
From the subsurface lithological data and chemical analysis
of 71 core samples, obtained through drilling reveals that the proposed
block of 47.63 hectares, having estimated resource of the order of
15.28 million tones, classified as indicated resource with UNFC code of
332. Limestone of the area has average 48.57% CaO, where as Silica
& MgO contents are within the tolerable limit. Deposit has no or very
thin overburden, continuous & sufficient thickness averaging 13.10
meter, without any intercalation of other litho units. Looking to the CaO
content, in association with other essential elements the aforesaid
deposits of limestone can be utilized in manufacturing of cement.
