GEOLOGY OF WARANGAL RURAL DISTRICT
The Warangal Rural District comprises of Archaeans, Puranas, Gondwanas and Recent Alluvium. Archaean rocks comprise of Granite Gneisses and schists, intruded by Dolerite Dykes. Puranas consisting rocks of sedimentary origin and are represented by the Pakhals and sullavais. The Gondwanas in the District mostly represented by the lower Gondwana Rocks and Recents are Laterites and Alluvium.

Archeans Dharwar Granites, Gneisses & Schists.
The Archaean Crystalline rocks are the oldest rock formations occupying about 15% of the total Geographical area of the District covering the Mandals of part of Parkal, Atmakur,Nekkonda , Sangem and Narsampet. The Archeans comprises of Two Major formations namely, Dharwara and Peninsular Granites complex.
The Dharwars in the District consisting mainly of banded ferrugenous quartzites and Talc-Chlorite Schists some important. The peninsular Granite complex chiefly comprise of Granites of varying composition. The Granites are generally exposed in the form of dome like masses of various sizes. They are Grey and Pink in colour, Medium to coarse grained and are also porpherytic in texture, consisting of mainly Quartz, feldspars etc., as essential minerals. In this formation, Quarry Leases have been granted for Grey Granites around Warangal Rural Area, since the Granite formations yielding huge sizes of blocks with attractive colour and texture, which are having good export potential market.
The Granites are intruded by numerous dolerite dykes, quartz and pegmatite veins at various places. The dolerite Dyke varies in length from few meters to kilometers and width varying upto 300 mts. The Dolerite dykes are commercially extracted under the commercial name of Black Granites, which are having good export market at present. Number of Quarry Leases have granted for Black Granite in these Dolorite dykes. The important Black Granite areas in the District falls, within the radius of 40 km from Warangal town. The deposits occurring around Redlawada is considered to be good, because of their capability to yield large blocks of sizes varying between 2 to 3 cubic meters and are considered to highly valuable. Other prominent areas of commercial importance in the District are Peddapuram, Bodduchinthalapally, and Pallariguda.
The Warangal Rural District has enriched with Mienral walth and the minerals occurring in the District area Laterite, Dolomite, Black Granite, Colour Granite and Building Stone & Road Metal.
Laterite: The laterite deposits of Warangal Rural District consists of blanket type and developed due to sub-aerial weathering of country rock under rtopical climatic conditions. It occurs between upper soil cover and underlying grey dolomite, is a residual ferruginous rock and weathered material rich in Iron oxides and Aluminium oxides. The Laterite mined in Chennaraopet (V) of Nallabelli Mandal has a good market in manufacturing of Cement and is consumed by Cement Plants.
Dolomite: Uses of dolomtie (MdCO3) are chiefly in matellurgical, refractory, steel and chemical industries. Thick Dolomite bands associated with the rocks of Pakhal Super group are spread over large areas, in Pakhal basin.
Dimensional Stones: The Warangal Rural District has a good potential for dimensional Stone Industry. The Black and Pink Granites are being quarried for the local market as well as for export market. Export variety Black Granite (dolerite) is being quarried at Bodduchinthapally, Peddapuram and Redlawada Villages etc. of Athmakur and Nekkonda Mandals. The Black Granite of good quality which can be quarried for local market are found at Mogilicherla and Lingavarigudem Vilalges of Geesugonda and Wardhannapet Mandals. The other Colour Granite can be mined at Athmkur, Parkal and Parvathagiri Mandals. The deposits occurring around Redlawada is considered to be good, because of their capability to yield large blocks of sizes varying between 2 to 3 cubic meters and are considered to highly valuable. Other prominent areas of commercial importance in the District are Peddapuram, Bodduchinthalapally, and Pallariguda.
Sand: The Warangal Rural District has Minor sand deposits found in Akeru Vagu spread over in Wardhannapet and Rayaparthy Mandals of the District. The sand deposits are utilised for local Civil Constructions going around the Mandals and Warangal Town. There are no Major Sand reaches identified and also no de-casting of sand from Patta lands.
