中文摘要:文章对会泽铅锌矿床的主要矿体进行了系统观察、采样,对其矿石进行了岩矿鉴定、化学分析(包括部分单矿物)和电子探针分析,并对其成矿作用做了探讨。首次在矿石中发现了自然锑,初步查明整个矿床中Ag,Cd,Ge,Cu,Sb等伴生元素的平均含量(wB/10-6)分别为121.77、660.99、62.10、203.78和169.87,认为它们是晚成矿阶段形成的。

Abstract:It has been held that the Huize Pb_Zn deposit contains comprehensive useful elements such as Ag, Cd and Ge. Nevertheless, the exact contents, modes of occurrence and distribution regularity of these elements, except for silver, are not clear. Based on systematic observation and sampling of the main orebody, the authors conducted rock and mineral identification, chemical analysis (including analysis of some individual minerals) and electron microprobe analysis of the ore rock, so as to understand characteristics of mineralization. Antimony was found for the first time in the ore. The mean contents of Ag, Cd, Ge, Cu, and Sb are 121.77×10-6, 660.99×10-6, 62.10×10-6, 203.78×10-6 and 169.87×10-6 respectively, and these associated elements were evidently formed at the late stage of mineralization. This ore deposit is a multistage hydrothermal deposit.
