Abstract:

The intrusive body Ⅲ in the Baogutu area is composed of two separate parts (Ⅲ1 in north and Ⅲ2 in south). The lithologic units in Ⅲ1 are granodiorite and quartz diorite and those in Ⅲ2 are quartz diorite, diorite and a small amount of pyroxene diorite. A fresh quartz diorite sample from the central part of Ⅲ1 was dated to 313±3 Ma by zircon SHRIMP. Intrusive body Ⅰ, Ⅱ, Ⅲ1, Ⅳ and Ⅴ were formed during 310325 Ma. The copper mineralization occurred in 316310 Ma.

Key words:  quartz diorite, SHRIMP age, Baogutu, West Junggar, Xinjiang
