The Tectonic Segments of Northeastern India and Associated Gold Mineralisation

Gold in Northeastern India is broadly distributed in three distinct tectonic segments viz., a) The Peninsular Shield extension comprising, mainly Precambrian to Tertiary lithostratigraphic components, b) The Patkai-Arakan-Yoma Mobile Belt comprising Cretaceous-Tertiary gently folded belt, and c) The Brahmaputra-Surma Plains comprising Quaternary clastic derivatives. The first two domains have primary source rocks of gold and PGE while gold has been recovered from the alluvium in the third domain. There is a need for conceptually sustained gold exploration efforts in the region.
