Genetic mechanisms and exhumation processes of the high-pressure (granulites) within the Eastern Himalayan syntaxis, Xizang

The Zhibai Formation Complex high-pressure granulites within the Eastern Himalayan syntaxis are a succession of high-pressure granulites as the youngest granulites in the world formed at the lower crustal root zones. Tectonically these granulites are assigned to the northeastern part of the Indian continent in a tectonically thickening setting and their metamorphism may be related to the intracontinental subduction during the collision between the Indian and Eurasian continents. The exhumation mechanisms of the granulites may be owed to the rapid uplifting of the Higher Himalayan crystalline rock series caused by large-scale detachment and normal faulting due to the combination of the upper flotational and lower gravitational processes.
