The Indian tectonic plate is undergoing an unexpected shift under Tibet. According to a study, this plate is splitting into two. This plate, along with the Eurasian plate, crashed into each other millions of years ago, forming the Himalayas and the Tibetan plateau. But the geological process and the tectonic interaction between the Indian and Eurasian plates have remained somewhat of a mystery. However, a study presented at the 2023 American Geophysical Union conference gives a clearer picture of Earth’s deep geological activity and an unexpected occurrence. For years, it has been believed that the Indian plate is sliding beneath the Eurasian plate. This continental collision started millions of years ago. The Eurasian plate is being pushed upwards. But recent discovery shows that that's not all that's happening. The Lower part of the Indian plate is peeling off and sinking into the mantle.Also Read: <a href="https://www.wionews.com/trending/what-is-at-the-centre-of-the-solar-system-not-the-sun-but-an-invisible-force-1762755209678">What is at the centre of the solar system?

A deep fracture in Earth's mantle is taking shape as the Indian and Eurasian plates collide and trigger a process called "delamination". Scientists say that the denser lower part of the Indian plate is peeling off as it collides with the Eurasian plate.
