Deccan Trading Company Pvt. Ltd., having an office at No. 120, Hoodi Apartments, Cunningham Road, Bengaluru, Karnataka - 560 052. The applicant intends to carry out a Geotechnical study to estimate the Resources and Reserves of Black Granite in the prospecting area, hence the proponent approach me S. Ilavarasan, M.Sc., to carry out a detailed Geological investigation. S. Ilavarasan, M.Sc., has decided to carry out the Geological evaluation and validation of the Black granite deposit. The primary objective of this study is to make a Geological and geophysical investigation of the Black granite, which is available in the study area moreover analyzing the physical properties like structure, Texture, Colour, Hardness, etc., to suitable for the Commercial exploitation in the Present Market position. The principle aim of this Reconnaissance Survey is to delineate Granite deposits to evaluate the resource and estimate the reserves of the granite in the area, over an extent of 1.51.5Ha of Patta lands in S.F.Nos. 1322/1A2, 1322/1B2, 1322/2, 1407/1A, 1407/3A, 1408/2B, 1410/1A2, 1410/1B and 1410/2B of Mallankuzhi Village, Thalavadi Taluk, Erode District, Tamil Nadu State along with Global Positioning System (in W.G.S datum-1984). The scope of the work is to assess the nature of the Black Granite deposit and its occurrence and distribution within the study area. Accordingly, the consultant undertook the various Geological studies, and this report is prepared based on the investigation conducted, field observation and its inference along with recommendations. 1 Geological Report Mallankuzhi Black Granite The study area has under consideration in quarrying operations earlier.

The nearest town is Thalavadi, which is about 5km on the Northeastern side where all basic facilities like Hospital, Communication centre, Schools, Police Station, and Bus terminus are available. The District Administrative Office and the District headquarters are available in the Erode town located at a distance of 95km on the southeastern side. 2 Geological Report Mallankuzhi Black Granite There is good approachable metal road is already existence on the southwestern side of the area, there is no other patta land encountered for the haulage and approach of Black Granite.

The gradient is gentle towards southeast and altitude of the area is about 790m to 795m above from MSL. The Black granite is clearly visible right from the existing quarry pit with physical weathering. The ground water occurrence in this area is about 52mts in summer and 47mts in rainy season. The average annual rainfall is about 575mm – 833mm. The climate is dry and the temperature rises up to 40oC in summer and falls down to 21oC in winter seasons. 3 Geological Report Mallankuzhi Black Granite The study area is a barren land and the area has been carried out quarry operation in earlier hence, this area does not fit for any agricultural activities. The surrounding lands are barren land and seasonal cultivation practiced in some places by lift irrigation method. The main crops are Paddy, Ragi, Maize, Beens, Groundnut and trees like Neem, Cocos nucifera, Cactus and thorny bushes are seen around the area.

Fig 2.0 Photographs of the Study area 5 Geological Report Mallankuzhi Black Granite 5.0 GEOLOGY: i) REGIONAL GEOLOGY The hard rock terrain of Archaean to Late proterozoic comprises of predominantly Granite, Gneiss, Charnockite, Khondalite group of rocks and their magmatic derivatives, supracrustual sequences intruded by ultramafic complexes, basic dykes, granites. The northern part of Tamilnadu, north of Noyil – Cauvery River is characterized by the occurrences of a number of Dolerite dykes in contrast to the areas south of Noyil – Cauvery River where the dykes are absent. The dolerite dykes in general trending is in WNW- ESE and NNE – SSE directions and rarely in N-S and NNW – SSE directions. In central part of Tamilnadu, ENE – WNW to NE- SW trending dolerite dykes (Black granite) are seen transecting the Charnockite in Kalrayan & Kolli Hills. Palaeo magnetic studies of some of these dykes indicate Mid-Proterozoic age. Due to emplacement of Dolerite Dykes along narrower plains of weakness, the rock on solidification develops cracks and fractures mostly along the contacts with the country rocks. The dolerite dykes are mostly emplaced as ‘swarms” in an area. Granites were formed from molten rock referred to as “Magma” formed at great depths within the crust of the earth. During the cooling process, some of the minerals grow into larger crystals of colours peculiar to those minerals or get aligned along certain preferred directions giving rise to beautiful colors and patterns. Such rocks that were formed at great depths during the Archaean age are now exposed at the surface of the earth as a result of the combined actions of wind, air, sunlight and water and weathering and denudation over the past several million years. The granitic group ranges in composition from granite, through granodiorities to adamellite, augite-diorite, monzonite, etc., and contains inclusions of hornblendic rocks.
