From Ocean to Mountains: A Geological Timeline of Convergence

By approately ately 55 to 50 million years ago, thee entire oceanic cruct of thee Tethys had been consumed, bringing the indian continental margin into direct contact with the Eurasian continental crust. Thi monumental tectonic event marked the onset of thee continental collision faxe that would ultimately give rise to the Himalayan mountain chain and thee meain Plateau.

The Continental Collision Phase

Continental crutt posses lower density and higher buoyancy compared to oceanic cruct, rendering it resistant to deep subduction into the mantle. As a result, wheren the Indian Plate collided with Eurasia, it could not sink benefiath the overriding plate as oceanic lithosfere had previously done.

How Faults Build Mountains: The Underlying Mechanics

Thrust Faulting andDuplex Structures

Thruss faults are propelled over younger, shallower strata. In the Himalayas, the thrusting is nott a simple planar process but involves a complex array of imbricate fans andduplex structures. A duplex is a stack of fault- bounded rock scies, insimpleg a deck of cards piled atop one another.
