Summary

Story summary

Recent studies challenge Émile Argand's theory on Himalayan formation, proposing a "crust-mantle-crust" model.
The Himalayas formed from the collision of Indian and Asian plates approximately 50 million years ago.
New simulations reveal a rigid Asian mantle sliver between the Indian and Asian crusts, offering support.
Critics assert that crust thicker than 40 kilometers cannot sustain the Tibetan Plateau.
These findings could transform global understanding of crustal dynamics and mountain formation.
