Tethyan Mountain System
Quick Summary
The Tethyan Mountain System, also known as the Alpine-Himalayan System, is a vast chain of mountains and plateaus stretching across Eurasia. It formed over millions of years due to the collision of continental plates, primarily the African, Arabian, and Indian plates with the Eurasian Plate.12
This system owes its existence to the ancient Tethys Ocean, which once separated landmasses like Laurasia and Gondwana. As these continents moved and collided, the ocean floor sediments were compressed and uplifted, creating mountain ranges such as the Alps and the Himalayas. The Himalayas, for instance, were formed as the Indian subcontinent collided with Asia, pushing up layers of rock. The Zagros and Bitlis mountains in Iran and Turkey are also part of this system, formed by the collision of the Arabian Peninsula with Eurasia.132
