A study suggested that the plate beneath Indian was splitting<\/h2>\n

A study has suggested that the tectonic plate located beneath India’s could be dividing into two.<\/strong><\/p>\n

India<\/a>\u00a0is the seventh largest country in\u00a0the world<\/a>, coming in behind the likes of Australia, Brazil and\u00a0the US.<\/a><\/p>\n

It’s said to be approximately 3.287 million km\u00b2 and, if it was to be divided vertically – it would become two countries each around the size of Mongolia.<\/p>\n

But India isn’t thought to be splitting vertically, and\u00a0scientists<\/a> believe it’s potentially sheering horizontally instead.<\/p>\n

The theory was first presented at the American Geophysical Union conference which took place in December 2023.<\/p>\n

The\u00a0study<\/a>\u00a0– titled ‘Slab tearing and delamination of the Indian lithospheric mantle during flat-slab subduction, southeast Tibet’ – looks into the formation of the Himalaya.<\/p>\n

The Himalaya is a mountain range spanning over five countries – India, Pakistan, Nepal,\u00a0China<\/a>\u00a0and Bhutan – and according to the Geological Society, ‘the Himalayan mountain range and Tibetan plateau have formed as a result of the collision between the Indian Plate and Eurasian Plate which began 50 million years ago and continues today’.<\/p>\n

The study – led by Lin Liu, Danian Shi, Simon L Klemperer et al. – started by investigating the levels of helium present in the Tibetan springs and presented a new theory about the plates that lie underneath the mountain range.<\/p>\n

The study found the levels of helium were higher in southern Tibet compared to northern Tibet, suggesting the Indian tectonic plate is splitting in two underneath the Tibetan plateau.<\/p>\n

The study then used ‘3D S-wave receiver-functions’ to analyze the Indian Plate.<\/p>\n

The receiver function technique works by using information from teleseismic earthquakes to image the structure of the Earth and its internal boundaries.<\/p>\n

The study details,\u00a0as published<\/a>\u00a0in ESS Open Archive: “Our 3D S-wave receiver-functions newly reveal orogon-perpendicular tearing or warping of the Indian Plate.”<\/p>\n

One of the images appeared to show evidence of the top and lower slabs of the Indian Plate appearing to detach.<\/p>\n

This subsequently suggests the Indian Plate is ‘underplating’ or ‘subducting’ beneath a ‘mantle wedge’.<\/p>\n

The study resolves: “Our SRFs objectively map depths to distrinct Indian and Tibetan lithosphere-asthenosphere boundaries across a substantial region of south-eastern Tibet.<\/p>\n

“The inferred boundary between the two lithospheres is corroborated by more subjective mapping of changing SWS parameters, and by independent interpretations of the mantle suture from mantle degassing patterns and the northern limit of sub-Moho earthquakes.”<\/p>\n

Basically, this means the Indian Plate would peel into two, opposed to breaking into two.<\/p>\n","protected":false},"excerpt":{"rendered":"
