The Indian plate (or India plate) is a minor tectonic plate straddling the equator in the Eastern Hemisphere. Originally a part of the ancient continent of Gondwana , the Indian plate broke away from the other fragments of Gondwana 100 million years ago and began moving north, carrying Insular India with it.

Due to continental drift, the India Plate split from Madagascar and collided with the Eurasian Plate resulting in the formation of the Himalayas.. The earliest phase of tectonic evolution was marked by the cooling and solidification of the upper crust of the earth's surface in the Archaean Era (prior to 2.5 billion years) which is represented by the exposure of gneisses and granites especially ...
Insular India was an isolated landmass which became the Indian subcontinent. Across the latter stages of the Cretaceous and most of the Paleocene , following the breakup of Gondwana , the Indian subcontinent remained an isolated landmass as the Indian Plate drifted across the Tethys Ocean , forming the Indian Ocean .
The epilogue of the tectonic evolution was marked by granitic and rhyolitic magmatic events, namely the emplacement of the Erinpura granite and the Malani Volcanics on the western side of Aravalli-Delhi orogenic belt. [4] This event is ranked third among the largest igneous province in the globe, with a total area of about 52,000 km 2 in India. [9]
In the Late Cretaceous (84 Ma), the Indian plate began its very rapid northward drift covering a distance of about 6000 km, [6] with the oceanic-oceanic subduction continuing until the final closure of the oceanic basin and the obduction of oceanic ophiolite onto India and the beginning of continent-continent tectonic interaction starting at ...
The northern sub-basin mainly consists of the northern part of the Bengal basin. It lies between the 'saddle' of the Garo-Rajmahal gap (submerged ridge) in the south and the Himalayan Front, which is part of the Indian states of West Bengal and Bangladesh. The shallowest part of the sub-basin is in the south, where Neogene sediments varies in ...
India is situated entirely on the Indian Plate, a major tectonic plate that was formed when it split off from the ancient continent Gondwanaland (ancient landmass, consisting of the southern part of the supercontinent of Pangea). The Indo-Australian plate is subdivided into the Indian and Australian plates.
Since tectonic uplift has significantly slowed down nowadays compared to when the collision has just started, the present day Indian-Asian collision region is dominated by erosional processes. Rivers like the Indus and Ganges, which originated from the Lhasa block, are therefore able to flow as transverse rivers and reach beyond the proximal ...
