摘要
The Mengxi porphyry Cu-Mo deposit located north of the Qiongheba granite in the Yiwu County, eastern Junggar, was characterized by the abundance of various ore-bearing veins and veinlets, such as quartz vein, quartz-sulfide vein and sulfide vein. On the basis of formation mechanics, veins can be classified into two types: Hydrofracture-filled vein and tectonic fracture-filled vein. According to dislocation along tectonic fractures, sliding fracture and thrusting fracture were recognized. Statistic result of volume fraction of veins in three drill holes of the line 14 show that the ore-bearing fluid were concentrated along a low north-dipping zone in a depth between 100 m and 400 m, which was corresponded to the location of ore-bodies. .
