INTRODUCTION The Eastern Region of Geological Survey of India was established in 1961 with the regional headquarters at Kolkata and Circle Offices of Bihar, Orissa and West Bengal –Andaman and Sikkim Unit with headquarters at Patna, Bhubaneswar, Kolkata and Gangtok respectively. The circle offices were mainly involved with the systematic geological mapping and assessment of mineral resources. At the Regional Headquarters there were specialized divisions like Engineering Geology, Map compilation, Geophysical investigation, Chemical Laboratory and Drilling Division. The activities were further expanded to Photogeology & Remote Sensing, Regional Integrated Survey, and Quaternary & Environmental Geology, Earthquake Geology and the Geodata Divisions. Subsequently the Circle Offices were redesignated as “Operation”. In the year 2000, two major changes took place as regards the operational coverage of Eastern Region. Operation Bihar & Jharkhand was split into Operation Bihar and Operation Jharkhand with headquarters at Patna and Ranchi. The erstwhile AMSE Eastern zone headquartered at Ranchi was amalgamated with operation Jharkhand. At the same time the Sikkim Unit (of Operation West Bengal) was delinked from Eastern Region and amalgamated with NER, Shillong. Thus Eastern Region now covers geographical area of 0.426 million sq km in the states of WB (88752sq km)-Andaman (8249 sq km), Bihar (94162 sq km), Jharkhand (79714 sq km) and Orissa (1,55,707 sq km). Geologically the main land part of Eastern Region represents: - Archaean -Proterozoic Rocks, hosting a majority of mineral occurrences in Orissa, Jharkhand and West Bengal. - Proterozoic Rocks, including limestone in the Vindhyans in Bihar and Jharkhand. - Gondwana Supergroup, a storehouse for coal, refractory clays and coal bed methane. - Late Cretaceous - Early Palaeocene Rajmahal traps equivalent of the Deccan Continental Flood Basalts. - The sub-Himalayan foothills covering Darjeeling and Duars with marine Gondwana, Siwaliks and the Pleistocene fan deposit - The Quaternary Indo-Gangetic Alluvium covering major parts of Bihar and West Bengal. The Andaman & Nicobar Islands on the other hand represents: - Dominantly post-Cretaceous Ophiolite–flysch–wacke sequence developed as accretionary prism and wedge resultant to the ongoing subduction process along the Indo-Eurasian Plate margin in the Bay of Bengal. PHYSIOGRAPHY AND TECTONIC FRAMEWORK Physiographically the Chhotanagpur Plateau region of central and south Bihar–Jharkhand can be divided on the basis of physiographic consideration into Ranchi and Hazaribagh plateaus. The former is the main plateau with general elevation of about 600m above m.s.l. in Ranchi district, has a flat to gently undulating topography with occasional ridges and gradually slopes down towards south- east into the hilly and undulating topography with occasional ridges of Singhbhum. To the north of Tatanagar, the Dalma hills rising about 500m to 600m from the plains with a prominent east-west trending hill ranges are flanked on either side by easily denuded phyllites and mica schists forming the plains. The vast Singhbhum Granite cratonic terrain is represented by a peneplane, which is highly intercepted by residual mounds and rock knolls. The drainage system of the area is mainly controlled by the Damodar, Ajoy, Subarnerakha, north and south Koel river forming different basins. The eastern fringe of Indian peninsula to a large extent constitutes part of the Eastern Ghats hill ranges which flanks the main cratonic part to the west. Geomorphology of the area is broadly 1 controlled by various regional geological and tectonic features. The prominent central highland is marked by linear hill ranges lending NE-SW in the southern part and WNW-ESE or E-W in the central part. It is separated from the low-level coastal plain in the east by a series of faults. The central highland is again separated by upthrusts parallel to its hill ranges from the western part of the state which is the continuation of the dissected central Indian plateau-land. The central highland is further cut-across by the NW-SE trending Mahanadi graben in Orissa along which the river flows from west to east, The Mahanadi and sub-parallel Brahmani lineaments form a tectonic zone which divides the central highland into a southern segment constituted of granulite facies litho assemblages continuing southwards into Andhra Pradesh, and a northern segment exposing ancient (Archaean) granite-greenstone assemblages continuing northwards into Jharkhand. The Eastern Ghats is separated by Northern Orissa Boundary Fault (NOBF) from the northern part of the central highland.The shield area of Jharkhand is predominantly occupied by Archaean Singhbhum granite batholith , flanked by Proterozoic supracrustals of Singhbhum Group, Dalma volcanic belt and vast peneplain area of Chhotanagpur granite gneissic complex in the north. The northern segment of the central highland and the western plateau-land bordering Eastern Ghats are similar in geological set up and are known respectively as the North Orissa Craton and Bastar Craton. While in the middle of it lies the Gondwana formations in Mahanadi graben bounded by faults, which have rich coal resources, some sectors of the coastal plains are mostly covered by Tertiary, and Quaternary sediments and low-level laterite.
