Context: Smt. Varsha Ashok Aglawe assumed charge as the 54th Director General of the Geological Survey of India (GSI), becoming the first woman to lead India’s premier geoscientific organization in its 176-year history.
About The Geological Survey of India (GSI):
What It Is?
- The Geological Survey of India (GSI) is the premier national geoscientific agency responsible for creating and updating national geoscientific data, carrying out mineral resource assessments, and conducting fundamental geological research. It functions as an attached office under the Ministry of Mines, Government of India.
Establishment & History:
- Early Beginnings (1836–1848): Began with early coal investigations by the East India Company. The term Geological Survey of India was first officially used by John McClelland in his 1848 report.
- Formal Establishment (1851): Established in 1851 primarily to locate coal deposits for the expansion of the Indian Railways network.
- Founding Pioneer: The continuous working era of GSI commenced on March 4, 1851, with the arrival of Sir Thomas Oldham, Professor of Geology at Trinity College Dublin, who served as its first Director.
Aim: To systematically document India’s terrestrial and offshore geology, assess national mineral and energy resources, provide objective geoscientific expertise for policymaking, and manage natural hazard risks.
Key Functions:
- Systematic Geological Survey & Mapping: Conducts ground, airborne, satellite, and marine surveys using geophysical and geochemical methodologies to document India’s surface and subsurface geology.
- Mineral Prospecting & Exploration: Explores and scientifically assesses national mineral, energy, and water resources, with an intensified focus on deep-seated and critical minerals (lithium, rare earth elements, copper, cobalt).
- Natural Hazard & Environmental Studies: Conducts geotechnical investigations for public infrastructure, seismotectonic evaluations, landslide zoning, glaciology, and natural hazard risk assessments.
- Geoscientific Data Repository: Serves as the national clearing house and central repository for spatial and geoscientific databases via modern geoinformatics platforms.
- Fundamental & Collaborative Research: Engages in multidisciplinary earth science research—including polar studies, paleontology, and climate change geology—in partnership with global and Indian academic institutions.
