About the Directorate of Geology & Mining, Assam
The state of Assam is located between lat 24° 7‘ N and 28° 0‘ N and Long 89° 45‘ E and 96° 00‘ E. The state is surrounded on the three sides of the North, the East and the South by hills and mountains. To the west it merges with the West Bengal and Bangladesh plains. The state has Brahmaputra valley in the northern part bordering Arunachal and the Barak valley in the southern part. In between two valley plains there is an area called the Karbi Anglong plateau succeeded to the south by the Dima Hasao Hills. The state is encompassing an area of 78,438 Sq Km representation 2.39 % of the total area of the country and a population of about 3.12 crore.
Assam consists of three geological structure units. The structural core of the region is the Karbi-Anglong plateau which is the extension of Shillong Plateau. The second structural unit is the Tertiary depositional zone, which has given rise to the folded hills of the North Cachar Hills Districts including the state’s highest Barail Range. The third structural unit comprises of the alluvium depositional plains of the Brahmaputra valley and the Barak Valley. The two plains came into existence in the quaternary period. From the geotechnical point of view, the state of Assam especially whole Northeast India falls in seismic zone-V. However, the state of Assam along with Northeast India lie in one of the world’s wettest monsoon belts. The state falls within sub-tropical humid climatic zone. The state experiences mostly pleasant weather in all seasonal variations.
The land of Assam is blessed with the immense mineral potential and other natural resources. The available major mineral resources found in the state are mainly of Petroleum & Natural Gas, Coal, Iron-Ore etc and the minor mineral are sand, China- clay, Silica, Granite , Limestone, Quartzite’s, Fullers Earth etc. etc.
The main functions and activities of the Directorate are systematic geological investigation and its assessment and estimation of mineral deposits of the state. The Directorate also strives for ground water monitoring & its exploration for sustainable development of ground water resources. The Directorate is also engaged in the work of geological disaster management like earthquake, landslides and any incidents time to time to mitigate the geological disaster as well as for its better preparedness.
The Directorate supports necessary administration and information to our lessee and potential investors. Directorate deals with all queries regarding major and minor mineral potentiality and its mineral legislation apart from its procedure for grant of mineral concessions.
