ABSTRACT

The present report pertains to prospecting of limestone in Kodana block of

Dhar district. The present work was commenced in the month of April 2018 and

continued till June 2018.The main object of present work is to delineate lateral as well

as depth wise extension of the Limestone deposit along with the quantitative and

qualitative appraisal to ascertain its industrial utility.

The study area is bounded between latitude N 22020�19.694�:

22020�48.374� and longitude E 74

055�52.989�: 74

056�10.224� and comes under

toposheet no.46 J/15.

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.

From the subsurface lithological data and chemical analysis of core

samples, obtained through drilling reveals that the limestone of the area have weighted

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.

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.

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

Page 7: Kosdana Dhar G2 Limestone - mineralresources.mp · area which are overlain by Bagh and Lameta sediments. The Archaean members are best exposed in river section of man, sukkar etc

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

Page 9: Kosdana Dhar G2 Limestone - mineralresources.mp · area which are overlain by Bagh and Lameta sediments. The Archaean members are best exposed in river section of man, sukkar etc

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

Page 10: Kosdana Dhar G2 Limestone - mineralresources.mp · area which are overlain by Bagh and Lameta sediments. The Archaean members are best exposed in river section of man, sukkar etc

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

Page 11: Kosdana Dhar G2 Limestone - mineralresources.mp · area which are overlain by Bagh and Lameta sediments. The Archaean members are best exposed in river section of man, sukkar etc

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.

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

Page 14: Kosdana Dhar G2 Limestone - mineralresources.mp · area which are overlain by Bagh and Lameta sediments. The Archaean members are best exposed in river section of man, sukkar etc

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

Page 15: Kosdana Dhar G2 Limestone - mineralresources.mp · area which are overlain by Bagh and Lameta sediments. The Archaean members are best exposed in river section of man, sukkar etc

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).

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

Page 17: Kosdana Dhar G2 Limestone - mineralresources.mp · area which are overlain by Bagh and Lameta sediments. The Archaean members are best exposed in river section of man, sukkar etc

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.

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.
