Discovery of Haerdaban Stratabound Lead-Zinc Deposit and Its Prospecting Significance, Wenquan, Xinjiang

The Haerdaban lead-zinc deposit is located in the Biezhentaoshan area of west part of the Western Tianshan, which belongs to Sailimu Cu, Pb, Zn, Nb, Ta, W and P metallogenic belt. Ore body, which is stable extension, occur in the low-grade metamorphic marine clastic rocks and carbonate rocks of the Middle Proterozoic Changcheng System. The main ore body is beds-, lens-like bedding output with banded, brecciated, and disseminated structure. Metal minerals in the ore are mainly galena and sphalerite. Moreover, mineral assemblages in gangue are simple, including calcite and dolomite. Compared with the Jiekeli strata-bound lead-zinc deposit in Kazakhstan, the Haerdaban lead-zinc deposit is similar to formed settings, times, locations, ore characteristics and quality. Preliminary analysis shows that its genetic types are stratabound type, which is discovered for the first time in Precambrian strata of western Tianshan. It is confirmed that the Jiekeli strata-bound lead-zinc deposit extended east to Sailimu area, Xinjiang, China. Furthermore, it is of great significance for lead and zinc exploration of the region in the future.
