Abstract: There exists a Sb anomalous belt of 700 km long in the eastern Kunlun Mountains, which represents an area of most intensive and wide enrichment Sb in Xinjiang. A large scale of Sb mineralization has been discovered at Huangyangling in the western part of this huge Sb anomalous belt. The Huangyangling Sb deposit contains four mineralization zones with the length of 1000-1500 m and width of 200-400 m each. A series of mineralized veins occurred in the detrital rocks of the Permian Huangyangling Group. The Sb mineralization with highgrade ores is closely related to the quartz veins. The Huangyangling Sb deposit may be a potential giant one. On the basis of Sb enrichment coefficient, orecontrolling factors, and spatial relationship between Sb mineralization and anomaly, we suggest that the eastern Kunlun Mountains be of favorable geological, metallogenetic and geochemical conditions to host large or superlarge Sb deposits in Xinjiang.
