The Chinese Altay orogenic belt (AOB), located along the boundary between the Siberian and Kazakhstan– Junggar terranes, is an important part of the Central Asian Orogenic Belt (CAOB), and hosts a series of polymetallic, rare metal (Li, Be, Nb, Ta) and nonferrous mineral deposits, e.g. the large-scale Mengku Fe (Cu), the largescale Kalatongke Cu–Ni, and the large-scale Keketuohai muscovite deposits. Besides, the Ashele Basin in the NW Chinese AOB has similar geological setting with the Kazakhstan AOB which contains more than 10 significant VMS deposits, and hosts volcanic-related Ashele Cu–Pb– Zn, Keketale Pb–Zn, Tiemu’erte Pb–Zn–Cu, and Sarsuk polymetallic Au deposits. Therefore, the study of the Chinese AOB provides important information to metallogenesis of the CAOB. The Sarsuk polymetallic Au deposit is a newlydiscovered medium-sized deposit, and is located at ~5.7km NNE of the Ashele Cu–Pb–Zn deposit, with few studies and poor understanding on metallogenesis. In this paper, we describe the metallogenic setting and geological characteristics, and discuss the genesis based on the geochronology of the Sarsuk polymetallic Au deposit.
