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 ...
Fig 4: The northward drift of India from 71 Ma ago to present time. Note the simultaneous counter-clockwise rotation of India. Collision of the Indian continent with Eurasia occurred at about 55 million years ago.

India's territorial waters extend into the sea to a distance of 12 nautical miles (13.8 mi; 22.2 km) from the coast baseline. [7] India has the 18th largest Exclusive Economic Zone of 2,305,143 km 2 (890,021 sq mi). The northern frontiers of India are defined largely by the Himalayan mountain range, where the country borders China, Bhutan, and ...
Therefore, the hypothesized oceanic Greater India Basin could have existed and separated a microcontinent from the major India craton. [9] However, rock records in the Greater Himalayan crystalline complex , which is located south to the Tibetan Plateau and should have contained remnants of the oceanic Greater Indian Basin if it had existed, do ...
The Deccan is a plateau extending over an area of 422,000 km 2 (163,000 sq mi) and occupies the majority of the Indian peninsula.Shaped like an inverted triangle, it stretches from the Satpura and Vindhya Ranges in the north to the northern fringes of Tamil Nadu in the south.
Map of prominent mountain ranges in India, showing Aravalli in north-west India. The Aravalli Range, an eroded stub of ancient mountains, is believed to be the oldest range of fold mountains in India. [10] The natural history of the Aravalli Range dates back to times when the Indian Plate was separated from the Eurasian Plate by an ocean.
The Western Ghats at Matheran in Maharashtra Oblique satellite view of the Deccan Traps Map of the Deccan Traps [1] The Deccan Traps are a large igneous province of west-central India (17–24°N, 73–74°E). They are one of the largest volcanic features on Earth, taking the form of a large shield volcano. [2]
