About GSI

• The Geological Survey of India (GSI) was set up in 1851 as a Government of India organization under the Ministry of Mines primarily to find coal deposits for the Railways. Over the years, GSI has grown into a repository of geo-science information required in various fields in the country.
• Its main functions relate to creating and updating of national geoscientific information and mineral resource assessment. 
• GSI’s chief role includes providing objective, impartial and up-to-date geological expertise and geoscientific information of all kinds, with a focus on policy making decisions, commercial and socio-economic needs. 
• GSI also emphasises on systematic documentation of all geological processes derived out of surface and subsurface of India and its offshore areas. 
• GSI, headquartered in Kolkata, has six regional offices located in Lucknow, Jaipur, Nagpur, Hyderabad, Shillong and Kolkata and state unit offices in almost all states of the country.
