GEOLOGY & MINERAL RESOURCES OF BANSWARA DISTRICT Banswara district is situated in the southern most part of Rajasthan. It is the smallest district after Dungarpur (atea-3855 sq. km.) in the state having 5037 sq. km.area. The district boundary in the east and south concides with the state boundaries of Madhya Pradesh and Gujarat, where as the northern and western boundaries coincide with district boundaries of Udaipur and Dungarpur districts, respectively. Topographically most of the part of the district is having rugged topography consisting of the rocks of pre Aravallis (Bhilwara Supergroup), Aravalli Supergroup, post Aravalli intrusives and Deccan traps. The mineral wealth of the district is constituted mainly by non-metallic minerals like rock phosphate, limestone, marble, dolomite, soapstone, graphite etc. The metallic minerals occuring in the district are manganese, iron, lead-zinc and copper ores. Recently presence of gold is reported in Jagpura-Bhukhia and Khamera-Undwala area of Ghatol tehsil by GSI/DMGR. Presently one major and three minor minerals are being exploited in the district. A total of 130 mining leases - i.e., six for major and 124 for minor minerals, are existing in the district. Geology Geologically the district comprises pre-Aravalli basement, Aravalli meta sediments, post Aravalli intrusives and younger (Cretaceous) flows. The Aravalli Group of rocks is found in Garhi, Shergarh and part of Ghatol and Banswara tehsils. The meta sediments are comprised of quartzite, mica schist, conglomerates, quarts-chlorite schist, phyllites, dolomitic marble and gneisses. The post- Aravalli intrusives are amphibolite, granites, pegmatite and quartz veins. The eastern and south eastern part covering Danpur and Kushalgarh tehsils, is occupied by Deccan trap basalt (Cretaceous). The Aravalli meta sediments are highly folded and intruded by post Aravalli granites. Small exposures of typical conglomarate are found between Padona and Potla in Kushalgarh tehsil. The conglomerates consists of pebbles of black rock embedded in the dark schistose matrix. The dolomites present in sallopat area contain stromatolites (organic sedimentry strictures) indicating the evidence of ancient algal life. The geological suecession of Banswara district can be shown as follows: Recent to sub Recent - Kankar, soil, conglomalates. Upper Cretaceous to Paleocene extrusives - Deccan trap /basalt. Post Aravalli Intrusives - Granite, Pegmatites, quartz, veins, Amphibolite Aravalli Supergroup - Phyllite, graywacke schist, meta volcanic, dolomite marble, limestone, gneisses, quartzite. Pre Aravalli's (Bhilwara Supergroup) - Schist and gneisses (B.G.C.) Mineral Occurrences Limestone Banswara district is fortunate enough to have extensive deposits of cement grade limestone. It is mostly crystalline in nature and belongs to Aravalli Supergroup. Large deposits of cement and high grade limestone are located near Khamera, Bari-Lalpura, Kalinjara, Kela Mela, Talwara, Umrai, Jambui, Mokhampura, Amarpura, Bhimkund, Patan, Surwania etc. Preliminary investigations reveal that more than 1000 million tonnes of cement grade limestone is available in the district which can sustain two to three major and several mini/ tiny cement plants. Depositwise details: Oda-Bassi Limestone deposit: The deposit is located about 40 kms. north-west of Banswara town between Paloda & Luharia on Banswara Udaipur road. The Nandli-SablaMunger (Dungarpur district) limestone belt of Aravalli Supergroup continues further south upto Oda-Bassi village and beyond in Garhi tehsil of Banswara district. The limestone is pink, grey and offwhite in colour, hard, compact and crystalline in nature. It takes good polish and a major part bf the deposit is being worked as marble. Investigations carried out by the state department of Mines .& Geology have established cl reserve of 30 million tonnes containing 45% CaO, 8% to 12% SiO2 and low MgO.

A reserve of 3 million tonnes of chemical grade limestone containing 53 to 54% CaO, has been assessed by departmental investigations comprising 225 m. drilling spread over 5 boreholes. Besides, additional reserves of 25 million tonnes of cement grade limestone containing 48% CaQ, has been inferred. A part of the area was held under M.L. by R.S.M.D.C. Bari-Lalpura Limestone deposit: The deposit is located near village Bari-Lalpura which lies 17 kms. from Banswara on Banswara-Dahod road. The limestone occurs in the form of 3 subparallel bands over a strike length to about 1 km. with 15 to 150 m. width. The limestone is crystalline, fine to coarse grained and whitish grey in colour. The department has assessed 15 million tonnes limestone reserves containing 45 to 54% Cao, 1% MgO and low silica. A part of the area was held under mining lease by M/s Kalyan Sundram Cement Ltd. who has also set up a mini cement plant of 200 TPD capacity near village Bari, but as major part of the deposit falls in forest, the plant could not come in production. Khamera-Undwala Limestone deposit: The deposit is located 35 kms. north east of Banswara on Banswara- Pratapgarh road. Limestone is continuously seen from Khamera to Undwala for a strike length of about 7 kms. and its width varies from 50 to 800 m. Limestone is fine to medium grained, grey in colour, hard, compact and at places crystalline in nature. Detailed investigations carried out by the State Department by putting 11 bore holes comprising 574 m. drilling, revealed a reserve of 386 million tonnes containing 50% CaO, 1.5% MgO and 4 to 60/0 SiO2.Thin bands of high grade limestone also occur in association with cement grade limestone. The deposit falls in reserved forest. Danta-Kela-Mela Limestone deposit: The Khamera-Undwala belt described above continues further in south beyond Mahi river for a strike length of about 5 to 7 kms. running through Waverikhera, Kela-Mela, Satinwala and Kunda to Danta villages. The limestone is grey in colour, fine grained, hard and compact. A reserve of-about 100 million tonnes of limestone containing 44 to 53% CaO, 1 to 4% MgO and 2 to 10% SiO2 has been assessed. The deposit falls in reserved forest. Makanpura-Undwala-Amarpura Limestone deposit: The northern extention of Khamera- Undwala limestone belt is exposed near Rawatpura, Makanpura and Amarpura villages in Ghatol tehsil. The deposit is approachable by BanswaraDhariawad tar road. Thin, parallel and discontinuous bands of limestone occur over a strike length of about 8 to 10 kms. having 10 to 100 m. width and are associated with dolomite. The limestone is grey in colour and contains 45 to 54% CaO, low magnesia and silica. Part of the area was held under mining leases. About 20 million tonnes limestone reserve have been inferred in the area. Surwania Limestone deposit: The deposit is located near Survania village which lies about 13 kms. south of Banswara on Banswara-Dahod road. Limestone is extending over a strike length of about 2 kms. and having 30 to 100 m. width. It is grey in colour, fine to medium grained containing 44 to 52% CaO. Inferred reserve has been put at 5 million tonnes which can sustain a mini cement plant. Part of the area is being held under quarry licence. Prathvipura, Patan and Bhimkund Limestone deposit: A 15 kms. long Aravalli limestone belt extends from Sakria-Kheda in north to Patan in south through Lorda, Prithvipura, Bhimkund, Panasi, Patan, Patiyal in Garhi tehsil. The width of deposit varies from 50 to 400 m. The limestone is coarse grained, crystalline, pink and off white in colour, at places it is banded. The area was investgated by the deptt. Chemical analyses of surface samples indicate 43 to 48% CaO but in some sections silica is upto 20%. Pink limestone occurring in the area takes good polish and can be used as marble, part of the area near Prithvipura and Lorda is held under mining leases for marble and also under quarry licence. In addition to above, limestone occurrences have also been found near village chhota Dungra, tehsil Kushalgarh for a strike length of approximaty 1 km. The analysis results show 35 to 48% CaO. Small bands of cement and high grade limestone also occur near villages Himmat Singh Ka Gada, Jhamboi etc. At many places limestone is dolomitic and crystalline in nature and it is mined as marble. The important locatiops are Vithaldeo, Kotharia and Khema Talai. The Limestone near Bhanwariya Talai, Oda-Bassi, Bhimkund (Prithvipura), Lorda etc. is also being mined as marble and desenbed below: Marble Marble, a variety of dolomite/crystalline times tone occuring in the district is generally medium to fine grained, white to creamish white, pink or greyish white in colour or with other shades, strips or spots and takes good polish. It is used as a monumentel stone, in buildings, carving, idols and flooring tiles because of its easy workability. In Banswara district marble deposits have been found in Tripura-Sundari, Oda-Bassi, Vithaldeo and Bhimkund areas. In Oda-Bassi and Bhimkund areas, the marble is calcitic, pink and greyish white in colour whereas the marble of other areas is dolomitc white to creamish white coloured. Deposit wise details are as follows :- Tripura Sundri Marble deposits: The marble deposit is located in the north and northwest of Tripura Sundri temple and is approachable by a 18 kms. long tarred road from Banswara. The area is comprised of crystalline dolomitic marble alongwith quartzite, phyllites, gneisses and intercalated bands of limestone of Aravalli Supergroup. The marble is white, off white in colour and fine to medium grained in texture. The impurities of iron and manganeses are found in the form of spots, bandings and smears of brownish colour, which deteriorate the quality and grade of the marble, The general strike of marble band is NW-SE with 40-55° south-westerly dips. The band is quite extensive i.e. abut 2 kms. long and 500 m. wide containing about 60 million tonnes geological reserves. This marble is continued further towards north-west near Kothara village and beyond Khema-Talai. This extension falls in reserve forest and only a part of Khema Talai block which is out of forest, has been leased out. A total of 21 leases are existing in tripura Sundri and 5 in Khema Talai area. Chemical analysis reveals that the dolomite of Tripura Sunctri area contains about 20% MgO, 30-35% CaO and low silica. White coloured dolomite suitable as marble, occurs near village Kothara (in north west of Tripura Sundri marble deposit) which extends for a strike length of 2.5 kms. having about 400-500 m. width. This area falls in reserve forest. Oda-Bassi marble depoist : The marble deposit is located about 48 kms. northwest of Banswara between Loharia and Paloda villages on Banswara-Udaipur state highway near Oda village. Chemically this marble is cement grade limestone containing 45 to 50% CaO, 8 to 14% SiO2 and less than 1% MgO. This marble intermittently runs for about 18 kms. from Padla-Jani, Nandli (Dungarpur district) in the north west to Oda-Bassi (Banswara district) in the south-east and further south upto Himmat Singh Ka Gada with some barren gaps. Width of the band varies from 30 to 400 m. The maximum width is near Oda-Bassi. The marble is compact, crystalline and calcitic in nature. It offers attractive shades of light to dark pink and banded variety (adanga). The impurities found sporadically include intercalation of chloritebiotite schist. Thin criss-cross veinlets of white quartz are common. On the basis of surface geological data, about 18 million tonnes of marble reserves have been assessed in this area. Marble mining in this area is being carried in 31 leases. Part of the area, (about 1 km. long and 100 to 400 m. wide), falls in forest. this is also a good quality marble capable of yielding sizeable blocks. Vithaldeo marble deposit - The deposit is located at 17 kms. southwest of Banswara. It ia 4 km. south of Tripura Sundri. Marble is dolomitic in nature and occurs in the form of a 1.5 to 2.0 km. long and upto 800 m. wide band. It is white in colour and fine grained. Spots and smears of brownish colour of iron and manganese are seen. Three sets of sparsey spaced joint planes are there which facilitate in exploiting sizeable blocks. On the basis of surface geological features, about 45 million tonnes reserves of marble has been estimated in this area. Bhimkund marble deposit - The deposit lies about 25 kms. southwest of Banswara in form of 7-8 kms. long band of crystalline limestone. It starts in the southeast from village Patan and continued in the northwest upto Bhimkund. where marble band is about 2 km. long and upto 500 m. wide. It is fine to medium grained, "light to dark pink in colour with off white bandings and smears. it takes good polish. The general trend of marble band is NW -SE. This limestone/marble contains 42 to 46% CaO, 14 to 18% Si02 and less than 1% MgO. The rough estimation of the geological reserves of this marble deposit worked out on the basis of surface geological data, has indicate.d presence of about 37 million tonnes of marble reserves. In addition to the above, there are some more bands of crystalline limestone (marble) at Patan, Talai where some marketable blocks can be extracted, but the areas fall in reserve forest. Dolomite It is a double carbonate or calcium and magnesium. It occurs near Vithaldeo, Tripura Sundri, Khema-Talai, Bhanwaria Talai, Jagpura and Khamera. Dolomite of Tripura Sundri-Kothara and part of Khamera areas. at places it is of flux grade and can be used in steel industry, for which decripitation and burning tests are required to be done. Soapstone Soapstone deposits in Banswara district are located near Jagpura, Pipalkhunt, Khundri, Duduka, Mandela, Jamoi, Himmat Singh Ka Garha and Rohaniya areas. It also occur near Kherwa (Nerughati), Delwara and Abdulla Pir. Soapstone is found associated with Aravalli dolomites. It occurs as narrow veins ranging in thickness from few cantimetres to 2 metres. Soapstone is foliated to massive and is generally white, pale green, greenish white and dull grey in colour. The soapstone is of paper/DDT to cosmatic grade. About 0.27 million tonnes reserves have been estimated from these areas. Underground mining is being carried out in Jagpura area. Graphite Graphite is one of the important minerals of the district located during digging foundation of Mahi Bajaj Sagar Dam, at about 15 km. east of Banswara town. Graphite finds use in the foundry, crucibles, pencils, paints and in lubricants. The prominent graphite deposits found in the district indluded 35 km. long belt extending from Ghatol in north to Khandu in south. It occurs near Mahi dam (Tamtia), Kesharpura, Sasakota, Pachalwasa, Ghatol-Khandu, Bhimsor, Dukwara, Kundal, Chanduji Ka Garha, Amarthun, Bassi etc. About 5 million tonne reserves have been estimated in part of the belt around Mahi dam, Ghatol, Sasakota etc. The carbon content varies from 5 to 20%. Some samples from Bassi have indicated fixed carbon upto 30%. There were two mining leases of graphite in the district, which are of Rajasthan State Mineral Development Corporation. The mines are located at Tamtia and Chandu Ji Ka Garha. This graphite was subjected to beneficiation for up gradation in a small plant near Mahi dam site. Rock phosphate Rock phosphate occurs near Sallopat Ram-Ka-Muna and Khermati areas. It is in identical litho association as that of Jhamarkotra. The phosphorite zone which comprises 10-12 detached and folded lenses, occurs in central part of 3.2 km. long NW-SE trending dolomite band near Sallopat. The phosphorite is stromatalitic, banded, massive and bracciated in nature containing 13 to 35% P2O5. Small occurrences of phosphorite have also been located near Ram-Ka-Muna and Jhermati where P2O5 content does not exceed 15%. The phosphorite occurrences. of these two areas have indicated a shallow water depositional zone. About 1 million tonne reserves have been estimated in Sallopat area. R.S.M.D.C. had exploited rock phosphate deposit near Sallopat. Granite The occurrences of granites are seen near Pipalkhunt, Ghatol, Mudasel, Jhupel etc. Some of them take good polish but due to fractures, no sizeable blocks can be extracted. Most of these areas fall under forest Building stone The district is rich in building stones. Various rock types used for building stones are quartzite, limestone, dolomite, schist and basalt. Schist and slate stone are being quarried near Kanglia and Adhaiwali in tehsil Bagidora. Presently there are 11 mining leases for masonry stones in the district. Manganese ore In Rajasthan, the workable deposits of manganese ore are found in Banswara district only. The manganese ore found in the district contains pyrolusite, braunite and psilomelane minerals. These occur in association with phyllites and quartzites of Aravalli age. Manganese ore with 22 to 48% metal content occurs in a 24 kms. long and 30 to 70 m. wide belt near villages Sivnia, Khunta, Intala, Bhatra-Tambeara, Rupakhedi etc. On a rough estimate, the belt may carry a reserve of about 2 million tonnes of ore. These deposits have been worked extensively in the past but the mineral could not withstant competition due to adverse market condition, its low grade, distance from sea port and lack of transport facility. The important draw-back of the ore is presence of phosphorous and sulpher as impurities. By suitable benefication techniques, the ore can be up-graded and marketed. Department has carried out drilling operations in Tambesra arae to know the nature and reserve of managnese ore. Investigations have revealed that nature of the ore does not change at depth. Manganese ore is also found near Sagan, Tripura-Sundri, Kotharia, Goika, Baria and Khunta. Presence of extensive old workings in these areas indicate past mining activities. Iron Ore Large and extensive old workings have been found near Loharia for a strike length of about 2 kms. associated with farruginous quartzite. The ore contains about 45% iron. Loharia was good centre of iron smelting and for the manufacture of useful articles made of iron. These old workings have also been reported at Talwara, Khamera, Kherwa, Undwala, Jagpura, Delwara Bhuibodra. No attention has been paid, so far, to explore these iron ore deposits because consuming centers are far from the district. If required the ore may have to be upgraded. Copper, Lead, Zinc, Silver ore Extensive old workings and indications of basemetals in the form of gossan, malachite encrustations, slag heaps, spacks of primary sulphides etc. are found at several places in the district. G.S.I. and state department of Mines & Geology have carried out preliminary investigations including test drilling and sampling in some of the sreas near Pipalkhunt (Karabilla), Khaka, Jharka (Tamba-Dungri), Tejpur-Hadmatia, Khodan, Gojparla, Amarthun, Wardia, PadIa, Undwala, Kherwa, etc. Small mineralized zones have been established in Goj area, but no where commercially viable deposit of basemetal has been established, so far, in the district. NobleMetals Indications of silver mineralization were located by the state department near Kherwa, tehsil Ghatol. Investigations were carried out but Argentite bearing pegmatite was not found to occur in depth and thus, commercial viability has not been established. Recently Geological Survey of India has established presence of gold in Jagpura-Bhukhia area of Ghatol tehsil. A part of this area has been leased out to M/s Hindustan Zinc Limited for mining of gold. State Department of Mines and Geology, Rajasthan is also investing gold in Sadri-Undwala area where gold upto 0.1 ppm has been analysed in the core samples. Foreign entreprenears like M/s Meridian Minerals, Australia, BHP etc. had carryed out investigations in Banswara district in colloberation with State Department, GSI and HZL. It is hopped that in coming years, Banswara will become a gold producing district in the State. Mineral administration Mineral administration work in the distt. is being looked after by the Asst.
