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.

Map showing the Indo-Australian plate (IA) and other major plates The Indo-Australian plate, shown as its two subdivisions: the Indian plate (red) and the Australian plate (orange) The Indo-Australian plate is or was a major tectonic plate. It is in the process of separation into three plates, and may be currently separated into more than one ...
The Greater India Basin hypothesis suggests that there was a two-stage collision between India and Asia continent. [9] The first stage occurred at approximately 50 Ma, where a microcontinent from the Indian plate collided with the Asian continent. [9]
The Himalayan tectonics result in long term deformation. This includes shortening across the Himalayas that range from 900 to 1,500 km. Said shortening is a product of the significant ongoing seismic activity. The continued convergence of the Indian plate with the Eurasian plate results in mega earthquakes.
The Indian Plate broke up with the Australian Plate about 100 mya. [35] The Tethys ocean constricted as the Indian plate moved gradually upward. As both the plates were made of continental crusts, which were less dense than oceanic crusts, the increased compressive forces resulted in folding of the underlying rock bed. [36]
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 ...
The Indian subcontinent [note 7] is a physiographical region in Southern Asia, mostly situated on the Indian Plate, projecting southwards into the Indian Ocean from the Himalayas. Geographically, it spans the countries of Bangladesh, Bhutan, India, [note 1] Maldives, [note 2] Nepal, [note 3] Pakistan, [note 4] and Sri Lanka.
The Indian plate is part of the Indo-Australian plate, which underlies the Indian Ocean and Bay of Bengal, and is moving north-east at an average of 60 mm/a (0.075 in/Ms). The India Plate meets the Burma plate (which is considered a portion of the great Eurasian plate) at the Sunda Trench. At this point, the India Plate subducts beneath the ...
