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.
Abstract
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.
