Discovery and Significance of the Wengul Lead-Zinc Deposit in the Altun Region
The Altun region is an important lead-zinc mineralization prospect in China,and known lead-zinc deposits are mainly distributed in the Early Paleozoic Ordovician strata of the eastern section of Altun.The Wengu'er lead-zinc de-posit is an important newly discovered ore deposit in the Altun region.Two ore bodies have been preliminarily delineat-ed,with a length of 1820-2742 meters and a thickness of 2.03-59.87 meters,Zn grade ranges from 1.39％to 47.58％,The Pb grade ranges from 0.84％to 6.11％,and it is preliminarily speculated that the lead-zinc deposit is large to ultra large.The ore body is located in the second and third sections of the Jinyanshan Formation of the Jixian system,mainly com-posed of dolomite,mud crystal dolomite,etc.The main minerals are smithsonite and lead ore,followed by pyrite and chalcopyrite,with a small amount of primary sphalerite and galena.It is preliminarily inferred that it is an MVT type lead zinc deposit.The discovery of the Wengu'er lead-zinc deposit fills the gap in the exploration of lead-zinc deposits in the pre Cambrian metamorphic basement of the Altun area,and has important indicative significance for regional lead-zinc deposit exploration.
