OF
BHARATPUR DISTRICT
The district of Bhartpur, takes its name from the town of Bhartpur, which is also the district
headquater.prior to the Formation of Dolphur.
District, Bharatpur was the eastern most districts in Rajasthan. The district lies between 26°44 to
27°50. North latitude and 76° 53' to 77° 40 east longitude. The district covers an area of about
5066 sq. kms. The district is irregularly rectangular in shape. It forms boundaries with Gurgaon
district of Haryana in north, Agra & Mathura districts of Uttar Pradesh in east, Alwar district in
west, Sawai Madhopur in south-west and Dholpur in south. The district comprises 10 tehsils
namely, Pahari, Kama, Nagar, Deeg, Kumher, Nadbai, Bharatpur, Wer, Bayana and Rupbas.
Bharatpur is well connected by road and rail to other cities in India. The National Highway No.
11 passes through Bharatpur connecting it with Jaipur (181 Kms.) and Agra. Bharatpur is an
important junction on Delhi-Bombay main broad gauge line of western railway with branch lines
to Agra & Jaipur. The nearest airport is Agra in U.:P.
Physiographically, the district comprises alluvial plains, with detached hills in north and low
narrow ranges in western & northwestern parts.
The terrain in Bharatpur & Nadbai is plain while that of Bayana & Rupbas tehsils is diversified
by hills. The main rivers are Banganga, Gambhir, Kakund, Ruparel and Parvati.
Geology:
Almost the entire northern part of the district is covered by alluvium, with few isolated hills of
schist & quartzites belonging to Aravalli & Delhi Groups.
Geologically Bharatpur district comprises of rocks belonging the Aravalli Super group, Delhi
Super group and Vindhyan Super group. Statigraphic succession of the rock units of Bharatpur
region is as given below: (Based on the classifications proposed by Hacket, Heron, Sant &
Sharma, Singh etc.

Aravalli Súper group
The Pre Delhi rocks include schists, Phyllites, quartzite and highly altered basic rocks (probably
Volcanics). The Delhi Super group is characterised by a thick pile of conglomerate - quartzite
assemblage of Alwar Group, and lower part of the Raialo Group, basic volcanics and quartzite
inter beds of the upper part of Raialo Group, arenaceous rocks of weir formation and phyllites
and shales of Kushalgarh formation of Ajabgarh Group. During the first phase of Delhi orogeny
the Bayana sub-basin is reported to have suffered northerly monoclinal tilting. Resulting in very
open monoclinical fold with NW –SE to WNW- ESE axial trend superimposed in the limb of
earlier folds.
Ajabgarh group disconfirmably overlies the Alwar group comprising litho assemblage of
carbonaceous shale, phyllite ferruginous quartzite & white quartzite. Nature of contact between
Alwar and Ajabgarh groups is not clear though it's observable near village Hathori. Milky
white, grey and pink quartz veins and also the jasper veins are the abundant post Delhi intrusive
of the area. These are either along the regular joint planes, irregular fractures or in the Form of
gash veins. In places, quartz veins occupy the tensional fractures in the hige zone and in other
places they are cofolded with the primary bedding. The Delhi Super Group sedimentations has
taken place in the coastal environment of unstable shelf, characterized by intermittent vertical
tectonics. Vindhyan Super group of rocks assemblage is represented by sand stone and shales
etc, which are exposed in the north eastern part of the district in Rupbas Tehsil. Bhander
sandstone is underlain at places by light green to olive green shales.
Ground water potential
Irrigation wells & tube wells are the major source of water in Bharatpur district. River basins of
Banganga, Gambhiri, Ruparel and Chambal are prominent basins of the district.
Mineral Resources
Following are the rocks and mineral resources of Bharatpur district.
Barytes
Barytes mineralisation occurs over a length of 5.5 km. from west of Hathori to 2 km. WNW of
Ghatri. The area has been divided in to three blocks. These are Hathori, Karwan and Ghatri
blocks. The mineralisation is confined to the volcanic rocks related to Jahaz-Govindpura
volcanics of Delhi Super group.
Hathori Block - Five groups of barytes veins have been classified in .this block. The barytes
veins having 1.5 km. length and 5 to 10 cm width are emplaced along strike joints in the oldest
flow of this section. The mineral is transparent, white to grey in colour in the form of tabular
crystals. At places it has iron stains and shows association of hematite, limonite and vuggy
quartz, besides traces of chalcopyrite, pyrite and malactite. Good quality barytes from 2nd group
analyses Sioz-1.2-2%, Fe2O3 0.4%, Cao &Mgo in traces, Bao-64.4% & SO3-33.54%. A barytes
sample from the third group contains Sio2 2.43%, Fe2O3 0.28%, Al2O3 0.12%, alkalies less than
0.1%BaSO4- 97.02%.
Karwan Block: Barytes veins are emplaced along the cross & strike joints and irregular fractures
in flows, tuffbreccias and overlying quartzites. In general, veins are thin and show poor quality.
Barytes is grey showing iron staining and association of hematite and biotite.
Ghatri block: Barytes veins are emplaced along bedding and cross joints and irregular fractures
in flows, barytes veins with pinch and swell structures show maximum length of 4 m and 1 m
width. Mineral is translucent to opaque, with white to grey colour and massive to crystalline in
nature.
Sandstone
Sandstone of Vindhyan age is extensively mined in .Bharatpur. Splittable sand stone is available
near village Bansi Paharpur, Bandh Baretha, Turtipura, Tarsuman, Singhwali etc. Sand stone
varies in colour from buff-red to pink and creamish pink, at places spotted pink .is also seen.
Silica sand
Ferruginous-silica sand is located near Jaggiwanpura village 35 kms.away from Bayana railway
station. The sand occurs as thin bands of friable quartzite within the massive layers. Occurrences
of silica sand are reported near village Doravli and in the north of Karwan village. The sand is
ferruginous. The silica sand is being mined from the mines located in tehsil Bayana near village
Acholi, Gudakhar, Navali, Agawali, Bajoli, Talimpur & Jaswant nagar. In Kaman tehsil it is
being worked near village Kalawata, Nanerawas, Bol-kheda, Lahsar In Weir tehsil it is being
worked near village Mangren, Gothra and Mansapura. This district is the second largest producer
in the state next to Jaipur. On average sand contains 96 to 97% Sio2 and 0.15% to 0.5% Fe2O3
and sand recovery is about 50%. The silica sand of Kaman area is ferruginous but on
beneficiation in the ceramic ore dressing laboratory of the state department, it was upgraded to
98.2% Sio2 and 0.05% Fe2O3
Soapstone
Soapstone mineralisation is located near village Nidar (Teh. Bayana) Mangren (Teh. weir) Bilung
(Teh. Kaman). The soap stone is of low grade.
Saltpeter
A belt of nearly 800 sq. kms. Stretching from S.E. of Bharatpur to the N.W. of Kaman has been
located where the KNo3 efflorescence occurs, during the hot months from April to July.
Saltpetre appears as a very thin, slightly brownish yellow having moisture like appearance, crisp
encrustation on the earth surface. When the encrustation of the saltpeter is scrapped off from the
surface, it again appears within a weak, which can be again scrapped. If the scrapping is done
beyond the crisp layer, and the settled earth is scrapped the mineral may altogether stop to appear
by efflorescence. It is found that nearly 80 Kgs. of Potassium Nitrate is available from 2400 kgs.
of Potassium Nitrate soil i.e. the efflorescent soil contains 3 to 4% of KN03, though the
proportion varies from place to place. The villages producing good amount of KN03 are
AghapurDarapur, Bharatpur, Karot, Jogina, Gunsara, Sinsini, Deeg, Bhej, Kaman, Sikripatti,
Gopalgarh, Pipal Khera, Jorera etc.
Copper
Copper mineralisation is located near Khankhera and Ker village, nearly 25 kms. Due west of
Bayana Railway Station by road. The state department has done detailed prospecting work in the
area during 1976-77andestablished0.22million tonnes of 1.05% Copper in Kher block over a
strike length of 180 metre. Copper mineralisation is in form of lensoid body and largely restricted
to the silicified portions of metavolcanies
Lead
Lead mineralisation is located near Jotri and Piraka areas, located about 16 kms.due west of
Nogaon village. The area was investigated by state department. Lead mineralisation is confined to
quartz veins of superficial nature. The chemical analysis indicates very low values of Pb (less
than 1%)
Mineral based Industries
With the limited availability of minerals, the district has only small mineral based industries like
stone cutting units, brick units, lime kilns etc. There is a pottery company but it is using raw
material from out side district. With the increasing demand of sand stone such stone cutting units
may establish here.
Mineral Administration
Mineral administration work in the district is being looked after by Mining Engineer Bharatpur,
which is supervised by Superintending Mining Engineer Bharatpur. To check & curb the
unauthorised mining activities, one Mining Engineer vigilance is also posted at Bharatpur. The
geological work is carried out by office of Senior Geologist, Alwar, which is under
Superintending Geologist Jaipur. This office looks after geological work in Alwar, Bharatpur,
Dholpur and Dausa districts. The telephone numbers of these offices are given below:
1. Suptdg. Mining Engineer, Bharatpur (05644)-22421
2. Mining Engineer, Bharatpur (05644) 22128
3. Senior Geologist, Alwar (0144) 23899
During the year 1999-2000 one project has been proposed for geological work in Bharatpur
district.
1. Evaluation of sand stone deposits of Bharatpur district.
There are 20 leases of major minerals and 305 leases of minor mineral in the district and total
revenue earned during 1998-99 was 144 lacs.

LIGNITE IN RAJASTHAN
Lignite popularly known as brown coal is a lower rank premature stage coal, which
would have converted to black coal under favourable geological conditions in due course of time.
It is brown in colour, soft, friable, contain high insitu-moisture and volatile matter. Its calorific
value on in situ basis varies from 2,000 to 4,000 k. cal/kg.
First occurrence of lignite in Rajasthan was reported in 1896 while digging well at
Palana village in Bikaner district. The first mining activity by underground method commenced
in 1898 at Palana for utilising lignite primarily for power station of the erstwhile Bikaner State.
With the availability of hydro-electricity from Bhakhra, the demand of lignite went down and the
mining of lignite was suspended in 1967. After a gap of about 13 years, in 1980 the state
department of Mines & Geology restored the lignite exploration activities in Bikaner, Barmer &
Nagaur districts of Western Rajasthan and located good deposit of lignite in these districts.
To give a boost to the systematic and detailed exploration for lignite, Planning
Commission, Govt. of India constituted an Expert Group under the aegis of Neyveli Lignite
Corporation (NLC) in 1982, with G.S.I. & DMGR as its members. Detailed exploration work was
planned and initiated jointly by MECL, GSI & DMGR in the areas identified for each agency.
District wise brief account of lignite deposits is summerised below:
BIKANER DISTRICT :Palana :
It is located about 23 km. S.E. of Bikaner city. About 16.71 sq. km. area was prospected
by D.M.G. by carrying out about 35493.0 mtrs, drilling spread over 482 bore holes. The lignite
seams were intersected between 40 to 98 mts. depth with cummulative thickness of few cm. to
18.0 mts. The analytical results indicate that Ash content varies from 3.5-8% V.M. 20-35%, FC
21% and C.V. 3200-3500 K. Cal./kg. Based on exploratory drilling geological reserves of the
order of 23.57 M.T. were estimated in the area. The area was previously being worked for power
generation but due to fire in the mines, it was closed.
Barsingsar :
This area is located about 25 km. S.W. of Bikaner and 3 km. S.W. of Palana lignite area.
Barsingsar lignite prospect was located and explored by the state department and M.E.C.L. by
carrying out 35487.75 mts. drilling (313 bore holes) over an area of about 5.35 sq. kms.
Exploratory drilling has the presence of lignite seams at about 67 mts. depth. The thickness of
lignite seams varies from 6.30 mts. to 45.50 mts. The lignite of this area contains 2.4-10%Ash.
20-28% V.M., 16-28% F.C. and C.V. 3000 K.Cal/kg. Based on exploration data 77.83 M.T.
reserves have been estimated.
Gurha :
Gurha lignite deposit is located 22 km. N.W. of Kolayat. The Geological survey of India
first noticed the presence of lignite in the area. Detail exploration was initiated by state
department by carrying out 9428.35 mts. drilling in 76 boreholes over an area of 9.0 sqkm.
Exploratory drilling intersected 20 to 26.90 mts. thick lignite seam at 38m to 148.0 mts. varying
depth. About 38.00 million tonnes of reserves have been estimated in this area with 1:15 lignite
overburden ratio. Average ash content is 11.9%, V.M. is 31.81, FC is 21.28% and calorific value
at 45% in situ moisture is 2867 k. cal./kg.
Subsequently M.E.C.L. has carried out 42,867.85 mts. drilling in 322 boreholes in Gurha
east and west blocks. Total reserves in these two blocks are estimated to be around 50 million
