When the Indian subcontinent started moving northward How fast did it move towards the Eurasian plate?

How fast did India move toward the Eurasian Plate?

India drifted along at an unremarkable 40 millimeters per year until about 80 million years ago, when it suddenly sped up to 150 millimeters per year. India kept up this velocity for another 30 million years before hitting the brakes — just when the continent collided with Eurasia.

How did the Indian subcontinent drift into the Eurasian continent?

Based on the geologic record, India’s migration appears to have started about 120 million years ago, when Gondwana began to break apart. India was sent adrift across what was then the Tethys Ocean — an immense body of water that separated Gondwana from Eurasia.

Why did the Indian plate move so quickly?

India’s northward race towards Asia may be something of a plate tectonic speed record. The reason it moved so quickly was because it was attached to a large oceanic slab of lithosphere that was subducting beneath the southern margin of Asia.

Where did the Indian subcontinent drift towards?

During the breakup of Pangea, the Indian subcontinent became isolated from the southern part of Pangea, called Gondwanaland, at around 130 Ma, moved northwards and eventually collided with Eurasia to form the Himalayas at around 40–50 Ma2,3,4,5 (Fig. 1).
