Abstract
The eclogite, discovered in Liuyuan, occurs as lenticular enclave within gr anitic gneiss. It has typical features of eclogite in petrology and mineral ogy. The eclogite provides an important window to reconstruct the tectonic border of the Tarim block. The granitoids, located in Baihu area, yield U-P b zircon ages of 1 660-2 000 Ma (Palaeoproterozoic), which implies an early Precambrian basement in the area.
