Geology und Geography of the Chang Tang

The region of the Chang Tang covers an area of about 1.2 million square kilometers. The rocks on the surface of the Chang Tang plateau, which used to be a sea floor, are metamorph sediments, often folded in crazy structures.

The Chang Tang forms its own small tectonic plate and was lifted uniformly to an average altitude of about 4900 m when the Indian subcontinent collided with Asia. Therefore, the Chang Tang region is characterized by wide open plains and the central Chang Tang has no river drainage. From the wide plains of the Chang Tang, several high peaks with altitudes above 6000 m emerge like islands.
