GENERAL
Geological Survey of India (GSI) - A premier organisation of Earth Science Studies in the
sub-continent with a strength of 2900 geoscientists and technical professionals GSI has a network of Offices located in all the states of India
Custodian of Geoscientific database developed over a period of 150 years Capable of handling time-bound jobs in different subdisciplines of eath science: from
geological mapping to deposit modelling Equipped with modern laboratories run by professionals Possesses organisational setup to impart training in the fields of earth science Holds the key to mineral exploration
