Since inception, the Geological Survey of India started curatorial functions as a support facility to preserve the rocks, minerals, fossils and meteorites collected during field surveys, through exchange and as gift. Curatorial Division, Central Headquarters (CHQ) centrally co-ordinates the country-wide GSI activities on Museum, Geopark & Geological Monuments. It currently maintains three running geology galleries namely Siwalik Fossil Gallery, Invertebrate Fossil Gallery, Rock & Mineral Gallery displaying exhibits like rock, mineral and fossil specimens; models, maps with illustrations in the Indian Museum, Kolkata. Curatorial Division, CHQ also maintains Rock, Mineral, Fossil and Meteorite Repositories. GSI has also identified and declared 26 sites throughout the country as National Geological Monuments to focus attention on such marvels of nature and to protect and preserve these for posterity.
Beside CHQ, all the Region & State Units (SU) maintain geological museums displaying rock, mineral and fossil specimens; maps, diagrams, photographs etc. GSI is also committed in establishing State level museums at suitable places in all States in collaboration with the State Governments depicting the geological history and features of the State.
