Geology, geomorphology, lithology:- Geology, geomorphology, lithology, mineral resource & district resource map of Alwar is as under:- Alwar district in the northeast bordering Haryana, covers an area of 8380 km2. The district has ten tehsils namely Alwar, Behror, Bansur, Ramgarh, Kishangarh Bas, Laxmangarh, Mandawar, Rajgarh, Thanagazi and Tijara, falling in survey of india degree sheets 54A, E and 53 D. Large area of the district , however, falls in the degree sheet 54A and forms a part of the national capital region. The Delhi – Ahmedabad and the phulera – rewari metre gauge sections of the western railway are the network of metalled and unmetalled roads in the district . alwar district is connected to Delhi and jaipur by state Highway No. 21, semi arid to dry climate prevalls in the area. the average annul rainfall is 577mm. The district is characterized by a mature topography of more or less fiat topped hills forming the northern continuation of main aravalli range. Major part of the district is occupied by folded hill range which are densely forested and host the famous Sariska Game Sanctuary. While the eastern and northern,flood plain support intensive agriculture productions making alwar an agriculturally prosperous district of Rajasthan. The district comprises precambrain metamorphic and igneous rocks, belonging to the mangalwar complex of the bhilwara supergroup (Archaean) and Raialo, Alwar and Ajabgarh Groups, in ascending order superposition, belonging to the Delhi super group (Lower to middle proterozoic) and post. Delhi igneous intrusive auulvium and Aeolian sediments mask the older formations. The mangalwar complex comprising quartzite, mica schist, crystalline limestone, conglomerate and granite occur as isolated exposures in the southern part. These are unconformably overlain by the raialo group comprising a predominantly calcareous formations with volcanic and subordinate quartzite. These lie in the core part of regional folds, defined by the alwar groups of rocks. The alwar group defining the main structural pattern of the area contains a basal conglomerate and arkose quartzite unit followed by a sequence of 5 argillaceous and impure calcareous rocks. In the northem part, the alwar group passes conformably into the Ajamgarh group, with the gradual change from dominantly arenaceous facies to argillaceous facies. The post – Delhi intrusive include sills and dykes of amphibolites plutons of variable dimensions and pegmatite, plutons of granite of variable dimensions and pegmatite. The rocks of the Delhi super groups are affected by NNE – SSW trending large – scale folds and faults. Sr. Lithology Group Super Age no group 15 Alluvium and Quarternary Aeolian sand 14 Granite, Pegmatite Intrusive 13 Amphibolite, metadolerite 12 Gritty quartzite, quartzite with inter layered phyllites, carbonaceous phyllites and Lower to schist Delhi Ajabhgarh middle Supergroup 11 Phyllittte, Schist Proterozoic & minor marble 10 Brecciated quartzite 9 Impure marble, amphibole 6 quartzite 8a Massive quartzite locally feldspathic grity 8b schist 7 Scist phyllite, flaggy quartzite and minor Alwar marble Group 6a Conglomerate and gritty quartzite with basic flows at places 6b Quartzite 5 (a) Quartzite, (B) Feldspathic quartzite with interbedded bsic flows 4 Quartzite with thin bands of Railo Conglomerate Group 3a Feldspathic quartzite and conglomerate 3b Dolomitic marble 7 2 Granite and Bhilwara Archaean gneiss Supergroup 1 Quartzite with interlayered schist and phyllite Geomorphologically, the district is classified into six geomorphic units namely younger dune, older dune, oldest dune, older flood plain, palaeo – channel and denudational hill . Three river basins namely the sabi river Basin, the Banganga River Basin and the Barah River Basin have been superimposed over the geomorphology in this map. Natural hazards map shows areas prone to industrial pollution, water logging. Salinity and gully, wind, soil erosion etc. Mineral Resources- The district is endowed with a nuber of important mineral resources. Important barites deposit are located at sainpuri (27-46 : 76- 43), Babell (27-13 : 76-42), Jamrouli (27-09 : 76-40), Pehal (27-49 : 76- 33), Karoli (27-40 : 76-40), Rata(27-41 : 76-39) and thatra (27-13 : 76- 44). The mineral occurs as veins and fracture fillings in the quartzite and phyllite of the Alwar and Ajabgarh Groups. Alwar district leads in the production of barites in Rajasthan. Important deposits of copper are located at Bhagoni (27-17 : 76-24) with 5.22 million tone (M.T.)of ore with 1% Cu and Kho – Dariba (27-10 : 76-23) containing 0.56 MT of ore with 2.5% Cu. Minor prospects of copper mineralization are also located at Kalighati(27-18 : 76-25), Nalladeshwar (27-25 : 76-27), Pratapgarh (27-15 : 76-13) and Deota (27-49 : 76-45), other minor minerals occurring in the district are asbestos, calcite, china clay, fledspar, iron ore etc. asbestos occurrences are reported from Delawas (27-33 : 76-35), Guda (27-37 : 76-26), Palpur (27-12 : 76-24), thanagazi (27-24 : 76-19) 8 etc. calcite is reported from pehal, tatarpur (27-46 : 76-30) etc. Clay is reported from pharoli (27-09 : 76-49), Mudali (27-19 : 76-38), Kolgaon ( 27-42 : 76-47) etc. This occurrences are reported from jhiri (27-14 : 76- 12), Nangal Kheri ( 27-27 : 76-23), Gothari Guru (27-24 : 76-47) etc. Feldspar occurrences are located at tatarpur, khairthal (27-48 : 76-39) etc. Gamet is reported from toda (27-21 : 76-55), Mandawar, Kothal (27-43 : 76-18), Mohanpur (27-44 : 76-18) and Baraud (27-54 : 76-22), Sanauli (27-57 : 76-25) ridges iron and manganese occurrences are lockted at Rajgarh (27-14 : 76-38), Tehla (27-15 : 76-29), Khanpur (27-46 : 76-46), Akbarpur (27-27 : 76-31), Baraud etc. Dolomite occurrences are located south of Kho – Dariba.
