摘　　要：温谷尔铅锌矿为阿尔金地区新发现的重要矿点,初步圈定铅锌矿体2条,长1 820~2 742 m,厚2.03~59.78 m,Zn品位1.39%~47.58%,Pb品位0.84%~6.11%。矿体产于蓟县系金雁山组二、三段地层中,岩性主要为白云岩、泥晶白云岩等,主要矿物为菱锌矿、白铅矿,次为黄铁矿、黄铜矿,含少量原生闪锌矿、方铅矿,初步推断为MVT型铅锌矿床。温谷尔铅锌矿的发现填补了阿尔金地区前寒武变质基底MVT型铅锌矿找矿工作的空白,对区域铅锌矿找矿工作具重要指示意义。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 deposit is an important newly discovered ore deposit in the Altun region.Two ore bodies have been preliminarily delineated,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 composed 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 leadzinc deposit exploration.
