GEOLOGY & MINERAL RESOURCES OF
JAISALMER DISTRICT
Jaisalmer, the largest district of the state (38,401 sq. km. area) is situated in the northwestern part of Rajasthan between 2600 01' to 2803' north latitude and 69030' to 72020' east longitute.
Jaisalmer distt. is girdled by Barmer in the south, Jodhpur in the east and Bikaner in north-east. The
western boundary of the district is a part of Indo-Pak international border. The district head quarter
Jaisalmer is linked from Bikaner (330km.) and Barmer (153 km) by National Highway No. 15 and also
connected from Jodhpur by road (285 km) as well as broadgauge rail line (297 km) via pokaran. There is
a small airport at Jaisalmer and chartered air service operates from here.
Jaisalmer has only two tehsils viz (1) Jaisalmer (2) Pokaran and it is amongst the least populous district.
The lowest density of 9 persons/sq.km. is recorded for the district.
Jaisalmer is known the world over for its rich cultural heritage, the golden fort, beautiful artifacts and
and handicrafts, splendour of its architecture, colourful dresses, music and hospitality of its people.
Jaisalmer was founded by king Jaisal or Jaisa. The word "Jaisalmer" is said to have been derived from a
combination of words- "Jaisal and Meru"- a local name for Jaisal's fort.
Jaisalmer or the Goldencity as it is now called is famous for its fort and the stone carving in the old
Havelies, which are now famous world over. In the recent past it has become a major tourist attraction.
At Akal about 15 kms form Jaisalmer is the wood fossil park where wood fossils about 180 million
years old can be seen.
The general shape of the district is of an irregular polygon of seven sides. In general the district enjoys
plain topography without any plateau or hills. The areas is a sandy plain with a few rocky patches and
many sand dunes. Being a part of the great Thar desert, the area is sandy, dry and ill watered, unkind to
all forms of life (animal & plant). The entire area is barren and dreary, the only variation in the land
scape being a few hillocks and sand dunes. The land covered by the district slopes towards the Indus
valley Rann of Kutch. In the vicinity of Jaisalmer town the sand is stony containing numerous rocky
ridges & hard undulating plains formed of limestone and sand stone. There is no single perennial river in
the district. However with the construction of Indira Gandhi canal the northern part of the district has
become green & irrigated.
The water table in The district is very deep in absence of perennial streams. The depth varies form 38 to
46 mts. some ground water potential areas have been identified in different formations where tubewells
can be drilled.
Geology
Jaisalmer basin defined as NW slope of Indian peninsular shield which deepens Mari, Sui, and Quetta
in Pakistan. Jaisalmer basin is one of the largest basins of India which encompasses an area of 30,000
sq. kms. It is bounded in the north by the sub- surface Delhi-Sargodha ridge and to the east by western
flank of Aravalli mountain, to the south by two prominent uplifted blocks viz the Birmania- Barmer,
Nagar, Parkar, Arch and the Saurasthra Peninsula.
The basement rocks are the Metamorphites, Granites, and Rhyolites which are exposed near Birmania.
they are unconformably overlain by dolomitic limestone, shale and sandstone of the Marwar
Supergroup. Resting over these with unconformity are the Jurassic rocks made up of the Lathi formation
(sandstone, grit and veriegated shales with plant fossils), Jaisalmar formation (predominantly
fossiliferous limestone), Baisakhi formation (Siltstone, Shale and Sandstone with intercalations of
gypseous and bentonitic clays represent first marine transgression) and Bedesar formation (sandstone,
limestone and shales). These are followed by rocks of the Cretaceous system represented by
fossiliferous limestone and feldspathic sandstone and grit. (Habur formation represents second marine
transgression on the surface during cretaceous while in the subsurface this this is represented by the
Goru and the Parh formation).
Lower to middle Palaeocene represented by Sanu formation which consists of unconsolidated,highly
current bedded reddish, gluconitic sandstone and silty sandstone.
Upper Palaeocene to lower Eocene represented by Khuiala formation consists of limestone bouldary
bedded, fossiliferous Limestone, clays and shales, The Khuiala limestone (Yoresian) having a total
thickness of 100m. overlains the sonu sandstone is underlain by the Bandha limestone (Lutetian) of
75m. compacted thickness. This forms the close of the sedimentary cycle in Jaisalmer Basin.
The Sanu formation (Lower to Middle palaeocene) represents regression of the sea but the upper part of
Sanu and subsequent Khuiala (Upper Palaeocene to Yoresian) and Bandha (Lutetion) formation
represent the third marine transgression. There after marine conditions appear to have completely
receded from the Jaisalmer basin. Thus Mesozoic and tertiary sequences in the basin represent a typical
shelf zone sedimentation of orthoquartzite-limestone association resting on a peneplained Precambrian
surface. the Lathi, Jaisalmer, Baisakhi-Bedesar, Parihar, Ukra and Abur beds respectively are
correlatable to Patcham, Vhari, Katrol Umia and of Kutch shelf. A generalised stratigraphic succession

MINERALS OF JAISALMER DISTRICT
Jaisalmer distt. is renowned for its mineral wealth. It occupies a significant position on the mineral map
of the state. It possesses a wide range of mineral resources and offers considerable potential for further.
With the discovery of steel grade limestone and cement grade limestone the district has come into
limelight and already six areas have been offered for major cement plants. Jaisalmer has also shown
positive evidence of Hydro carbon accumulation (Natural Gas). The description of minerals occuring in
the district is given below:
GYPSUM
Gypsum is hydrated sulphate of calcium CaSO 4' 2HzO. Gypsum occurs mainly as thick, stratified
sedimentary beds or lenses, horizontal or gently inclined, varying from a few feet up to 8-10 feet in
thickness.
In Jaisaimer district gypsum deposits are reported in Mohangarh, Phalsund, Ghandan, Nokh,
Nachana,Satta, Sundra and Lakha Khadar areas, Most of the gypsum deposit of the district are just
surface deposits and are won by open cast mining method. In several mines, mining is done manually as
the gypsum beds are not of uniform thickness. Five leases for gypsum exist in the district & mining is
being done by Mis. FCI & M/s. RSMDC Ltd. .
SELENITE
Selenite is a crystalline variety of gypsum forming transparent foliated plates. It occurs as single or
twined crystals and is used in manufacture of plaster of Paris.
It occurs at Mohangarh, Hamir-wali-Dhani, Lakhera, Ramgarh, Bandha, Biprasar, Khuiala and Rupsi.
Selenite crystals occur embeded in matrix of marly clay. In Khuiala it is found in nala section near
Ubrakha-ki-Dhani intercalaled with bentonite having thickness about 5-7 cms.
BENTONITE
It is a naturally occurring clay of great commercial importance possessing j$erent bleaching properties.
The Bentonite is chiefly composed of about 75% of montmorillonite, the rest being kaolinite, attapalgite,
illite, chlorite, quartz, and feldspar.
Occurrences of bentonite are reported near Khuiala, Mandha, Khuri, Habur, Mandai, Ramgarh villages.
The deposits of Khuiala and Khuri prospected by the department of Mines & Geology, are of medium
grade, the reserves estimated are 2 M.T. and 1 M.T. respectively.
The Bentonite of the district is mainly of nonswelling type and has a lower ratio of soda to lime. It is not
suitable for oil well drilling because of plastic viscosity.
FULLERS EARTH
It is variety of non plastic montmorillonite clay which has a property to decolourize oil, fats and grease.
It is also used for washing hairs, Its occurrences are associated with Khuiala limestone at Khuiala and
Mandha areas of the distt. Near Mandha it is 0.60 to 2.75 mts. thickness and a reserve of 30 thousand
tonnes is estimated. Other occurrences are. reported near Ramgarh, Sanu and Dhol-ki-Dungari.
WHITE CLAYS
It is interstratified with sandstone of Lathi group at following localities
Kita : At Kita the clay occurs about 4 kms. NE of the village where two bands having average thickness
of apout 1 mt are reported and about 4 thousand tonnes reserve, estimated.
Devikot : At Devikot clay occurs at 2 km. SW of the village with thiCkness 1 mt. & having 29 thousand
tonnes reserve.
The tests indicate that the clays are refractory in nature and having low shrinkage but are not suitable for
use in pottery as they develop cracks on firing.
SILICEOUS EARTH
The siliceous earth also known as siliceous ooze (Diatomite) occurs in Jaisalmer district, at Dharivi,
Khurd, Mandai, Sajeet Mimbla . It occurs as thin bands grading into bentonite. Siliceous earth is
composed of cristobalite silica with minor montmorillonite, quartz and trace minerals.
Siliceous earth is regarded as an excellent filtering aid for colloidal solid solution like Beverage, Fruit
juice Syrups, Oils (Vegitable oils & Mineral oil), Antibiotic products, water treatment to remove
amoebic cysts and blood fluke larves, drugs and other pharmaceuticals items are all filtered through
silicious earth. It can be used as filler in paper, rubber, paints and plastic, as carrier of disinfectant like
D.D.T. as admixture in pozzolana cement, Due to low thermal conductivity it is used for the
manufacture of insulating bricks and as an anticaking agent in fertilizers, About 1.2 MT reserves have
been assessed from this district.
GLASS SAND
The deposits are reported from Lathi, Devikot and Pithal in Jaisalmer distt. The Lathi sandstone.
occurring near Lathi is pure white in colour and is spread over an area of about 20 sq. km. This
sandstone has given silica sand due to weathring. The quarriable section exposed workable Glass sand
upto 1.5 mts. to 2.5 mt. in depth has analysed SiO2 92 to 95% , Al2O3 1.2 to 3.99%,Fe2O3.63 to 1.29%
and MgO and TiO2 as nil, It could be utilised for the manufacture of Bottle Glass. About 14.4 M.T.
reserves have been assessed from this district.
DOLOMITIC CLAY
White fine grained dolomitic clay having good plasticity is found near village Chacha and, Udhaniya.
The clay is quite useful as filler in paper, textiles and paint industry.
YELLOW OCHRE
Small deposits of Yellow Ochre occur near Mandai with thickness of the bed varying from 0.25 to 0.39
mts. The over burden is 2 to 5 mts. thick. It is useful for painting of houses.
ROCK PHOSPHATE
Phosphorite or rock phosphate associated with limestone, chert, black shales and sandstone has been
located at Birmania and Fatehgarh. In Birmania phosphorite horizon extends up to 4 km. towards Kohra
in the south having 3 mt. thickness. The phosphate rocks at Birmania are calcarious or arenaceous. 4.34
million tonnes reserves were estimated with P2O5 content ranging from 10-11 %
At Fatehgarh, a 1-4 mt thick phosphorite horizon comprising oolites, pellets, coprolites, and replace
shells of fossils, is traced for about 12 kms. along the strike. The phosphorite horizon is found
interbeded with limestone. The P2O5 content ranges from 5% to 15%.
Phosphate nodules were reported in the Baisakhi shales near Rupsi and Nibh Doongar. Analysis shows
that smaller modules of this area contain PPs from 22% -27%. Mis. RS.M.D.C. Ltd. has been granted
lease for mining in this area.
JASPAR
It is a cryptocrystaline variety of Quartz and occur near village Chacha, Ramdevera & Pokaran. The
colour is red to yellow. It is used as an abrassive for preparation of emery stone and emery paper.
VOLCANIC ASH
Volcanic ash deposits are located near village Phalsund, Dantal, Fulasar, Swami-ji-ki-Dhani etc. It is
light green to yellowish in colour. A sample tested in the CGCRI, Jadavpur indicated that at the temp. of
1300°C it changes to molten glass which can be used for manufacture of various type of glass wares,
glass sheets etc.
YELLOW MARBLE
Jaisalmer is popularly known as golden city because fortress and residential buildings are build of
yellow fine grained limestone. This limestone is used as marble by cutting and polishing it as tiles. At
present it is being quarried near Mool sagar, Amarsagar, Chundi, Bhagata, Wajron ki Dhani and Cipla
etc. Yellow marble is a speciallity of Jaisalmer and its demand is rising day by day in India and abroad.
Yellow marble belongs to Jaisalmer formation and forms ridges, mounds and hillock. It forms the top
unit and at places where the bed is massive and 1-2 mt thick, the block mining is being done.
STEEL GRADE LIMESTONE
The occurrance of low silica high CaO limestone in Jaisalmer District was first identified in the year
1974. The chemical analysis of four samples indicated that the CaO content ranges from 53.04% to
54.04%, MgO from 0.71 to 1.00% and insolubles from 0.67% to 0.94%. The state department of Mines
& Geology started exploration in 1983-84 by driling and proved large reserves of SMS grade linestone.
Investigations are still continued.
Limestone occures near Sanu Habur, Khuiala, Hemaki-dhani, Nibya, Jethaa, Joshiowala gaon etc.
villages over an extent of about 100kms. with awidth varying from 1 to 9 kms. in maximum
encompassing about 600 sq. km. area. The belt extends in patches from south of Ramgarh to south of
Sanu in N-S direction and Khuiala in SW to Rata Madha in NW. SMS Grade limestone occures on top
having thickness of 1-3 mts. followed by chalky limestone which is of cement grade. The high grade
limestone also occurs in Jaisalmer district. The chemical analysis indicates CaO content from 53-54%
Si02 1-2%.
Total 585 MT reserves of SMS grade lime stone have been assessed up to 1996-97. Mining of SMS
grade line stone is being done in public sector by M/S RSMML & M/s RSMDC Ltd. Chemical grade
line stone is also found in Jaisalmer district near Jethwai etc and about 233.33 MT reserves have been
assessed.
CEMENT GRADE LIMESTONE
Jaisalmer is endowed with high reserves of cement grade limestone. Limestone occuring in Jaisalmer
formation is yellowish, massive & occurs near Jaisalmer, South of Moolsagar, Hamera, Amarsagar etc.
In the Khuiala formation SMS grade limestone is found at top followed by cement grade limestone. It is
also called as chalky limestone. It is moderately hard, white to light yellowish in colour earthy, lumpy &
fossilierous. The analysis of this lime stone indicated CaO 43-45% Si0211 % & MgO less then 2%.
Investigations have been carried out by state department of Mines & Geology for cement grade
limestone and so far 2018.94 MT reserves have been proved.
Six blocks have been identified for setting up of major cement plants. The details are given below:

Madli, Kohera Department of Mines & Geology has carried out investigation in above areas and
availability of blockoble granite is found over 100 sq.mt. area. This granite is medium grained brick red
in colour occuing as scattered outcrop in plains.
MINERAL FUEL
Attempts to explore hydrocarbons in Rajasthan dates back to 1956. ONGC has been carrying out
investigation for oil and gas since 1962. In 1981 under a major policy decesion, the Govt. of India
assigned a high priority to Rajasthan and in 1982 ONGC & Oil India Ltd. were allowed 14000 & 28000
sq.km. area respectively for exploration. The Jaisalmer basin has thick sedementary secton with positive
evidence of hydrocarbon accumulation. As a result of geo scientific exploration nine gas fields have
been identified by ONGC & OIL near Manhar Tibba, Ghoataru, Bakhri, Khartor, Bantua, Tanot &
Ramgarh. Agas based power plant of 35 MW capacity has been set up in Ramgarh and is producing
electricity.
MINERAL BASED INDUSTRIES
Industrially Jaisalmer is considered to be a no industries district. As such government provides help &
subsidy to entrepreneurs putting industries in this district. The main minerals which have scope for
establishing mineral based industries are high and cement grade limestone, marble, sandstone, siliceous
earth and natural gas etc.
Vast resources of cement grade limestone exist in the area and six areas have already been notitied for
setting up of major cement plants. Availability of chemical & high grade limestone paves way for
setting up of chemical industries.
Natural gas has been stuck in the district and one gas based power plant has started production near
Ramgarh. There is further scope for setting up of such plants. Jaisalmer is endowed with availability of
solar radiation through out the year and solar power plants can also be set up. Yellow marble and sand
stone of Jaisalmer is world famous and cutting & polishing industries can be established based on these
deposits. At present there is one Plaster of Paris plant, twelve marble cutting & polishing units, one
marble decorative article industry and twenty two crushers in the district. There is scope for setting up of
glass and ceramic industry. Gypsum of the district can be used for local manufacture of sulfuric acid,
bricks and wall boards.
MINERAL ADMINSTRATION
There is an office of Asstt. Mining Engineer at Jaisalmer which looks after the mineral adminstration.
The geological work is carried out by Superintending
Geologist, Jaisalmer. During the year 1997-98, 3 projects have been proposed for investigation.
