Scientists discover that one of the largest countries in the world is “dividing into two parts”

A team of geophysicists has presented a new study indicating that one of the world’s largest countries is splitting into two parts.

The theory was first presented at the American Geophysical Union conference held in December 2023.

The study – entitled Rupture and delamination of the Indian lithospheric mantle during flat slab subduction, southeastern Tibet – Researches the formation of the Himalayas.

The Himalayas are a mountain range spanning five countries – India, Pakistan, Nepal, China and Bhutan – and according to the Geological Society, “the Himalayas and the Tibetan Plateau were formed as a result of the collision between the Indian and Eurasian plates.” Painting that began 50 million years ago and continues today.

The study – led by Lin Liu, Danian Shi, Simon L. Klemperer and others. – He began studying the levels of helium found in Tibetan springs and presented a new theory about the plates that lie beneath the mountain range.

The study found that helium levels were higher in southern Tibet compared to northern Tibet, suggesting that the Indian tectonic plates are splitting in two under the Tibetan Plateau.

The study then used “3D S-wave reception functions” to analyze the Indian plate.

Future Function technology works by using information from seismic earthquakes to image the Earth’s structure and internal boundaries.

The study details, as published in the ESS Open Archive: “Our 3D S-wave receiver functions newly reveal vertical rupture or warping of the orogone in the Indian Plate.”

One image appears to show evidence of separation of the upper and lower plates of the Indian plate.

He later notes that the Indian plate is “underlain” or “subducted” beneath the “mantle wedge”.

The study concludes: “Our SRF zones objectively map depths to distinguish the Indo-Tibetan mantle and lithosphere boundaries across a large region of southeastern Tibet.

“The inferred boundary between the two lithospheres is supported by more objective mapping of SWS variables, and by independent interpretations of mantle sutures from mantle unloading patterns and the northern limit of seismicity beneath the Moho.

“The southern limit of the Tibetan lithosphere and adjacent asthenosphere is at 31°NW90°E, but extends south by >300 km to ~28°NE92°E, likely representing plate rupture.”

Essentially, this means that the Indian plate will be divided into two parts, instead of splitting into two parts.

The study indicates that the upper half will protrude and cause Tibet to rise upward, while the lower half will sink further into the mantle.

“We didn’t know that continents could behave this way, and this is very fundamental for solid Earth science,” Douwe van Hinsbergen, a geodynamicist at Utrecht University, told Science magazine.

Fabio Capitanio, a geodynamicist at Monash University, adds that the data is limited at this stage – and the study has not yet been peer-reviewed – noting: “It’s just a snapshot. It’s definitely the kind of work we need to move forward.” “
