Geology of Great Nicobar Island

The Joint Scientific Expedition to the Great Nicobar Island provided opportunity for obtaining a comprehensive knowledge of the major geological features of the island. The various rock formations were examined and their stratigraphic sequence was established. Major structural features were noted and the geological history of the island is reviewed. This reveals a close similarity with the geology of Andaman Islands. Other aspects studied are economic geology, nature of soils and water resources.
