    Geological Survey of India (GSI)

    The Geological Survey of India (GSI), the second oldest survey in the country was established in I85l with the singular aim to locate coal for the railways. GSI over the years has expanded its role to undertake elucidation of the geological set up of the country, including assessment and regional level exploration for coal and other mineral resources, inputs to engineering projects, geotechnical studies, geo-environment and natural hazards, glaciology, seismotectonics etc.

    GSI is the prime provider of basic earth science information to the government, industry and the general public, as well as responsive participant in international geoscientific fora. The vibrant steel, coal, metals, cement and power industries which expanded phenomenally in the post-independence era, bear eloquent testimony to the GSI’s relevance in the national context.
