Ground and Marine Surveys
Ground and Marine Surveys - Reports

Ground Surveys consist of Systematic Geological Mapping (SGM) at scale 1:50,000, Specialized thematic mapping (STM) at scale 1:25,000, National Geochemical Mapping (NGCM) at scale 1:50,000 and National Geophysical Mapping (NGPM) to carry out the land gravity and magnetic surveys at scale 1:50,000. SGM is the most fundamental and basic mapping programme adopted by Geological Survey of India in last few decades through which. 98.52% of the total mappable area of the country has been covered.

Marine and Coastal surveys (M&CS) are carried out both in the Exclusive Economic Zone (EEZ) and Territorial Waters (TW) along the East and West Coasts of India and around Andaman Islands. The aim is not only to discover the undersea economic minerals, but also to unravel the evolutionary history of formation of the seabed developed under the influence of various dynamic processes operative on different scales in different parts of the globe.
