Fluid inclusion characteristics of the Xiejiagou gold deposit in Eastern Shandong province, China

摘要

The Xiejiagou gold deposit, founded in 2001 with the resource of 37 t Au, locates in Zhaoyuan city, Shandong province, China. The previous gold exploration and geological studies in Shandong province mainly focus on the large-scale fracture fault belts such as the Zhaoyuan-Pingdu fault Jiaojia-Xincheng fault and Sanshandao fault. While the Xiejiagou gold deposit occurs 3.5Km west to the Zhaoyuan-Pingdu fault, controlled by its sub-fault and a ductile shear zone. So the discovery of this deposit is a great breakthrough in the gold exploration in Shandong province. This paper mainly introduces the newest research result on the temperature, composition, H-O isotope etc of the fluid inclusions in the Xiejiagou gold deposit, then discusses the origin and evolution of ore-forming fluid.
