Abstract

Abstract

Laguigangri Mountains are composed of a series of chain-like swellings trending west and east. They all are vaults where there are a lot of metamorphic rocks and detachment faults, and so they are naturally related to each other. The research of chemical composition and metamorphic zonation and estimation of p-T of characteristic metamorphic minerals from metamorphic zone in Laguigangri has revealed the regularity of composition, temperature and pressure and metamorphic depth. This will evidence the activities of the metamorphic core and the detachment fault.
