广西龙胜县柚子坪铅锌矿地质特征及找矿远景探讨

ANALYSIS ON THE GEOLOGICAL FEATURES AND ORE-SEARCHING PROSPECTS OF THE YOUZIPING LEAD-ZINC DEPOSIT IN LONGSHENG COUNTY, GUANGXI

摘要: 柚子坪铅锌矿产于新元古界丹洲群地层中，矿区已圈定6个矿体，呈脉状、透镜状产出，矿体受北北东向及北东向断层构造控制.矿石矿物组成相对简单，垂向上具有上富铅下富锌分布特征.矿床成因类型属于岩浆期后中低温热液型，主要成矿期为加里东期.通过对柚子坪铅锌矿成矿地质条件、矿床地质特征、控矿因素等特征分析，结合物化探测量结果，认为矿区深边部具有较好的找矿远景.

Abstract: The Youziping lead-zinc deposit in Longsheng County, Guangxi is hosted by the Neoproterozoic Danzhou group. Six orebodies, in veined and lenticular shapes controlled by NEE- and NE-trending faults, has been recognized. The ore mineral composition is relatively simple, with lead concentrated in the top and zinc in the bottom. The deposit genetically belongs to post-magmatic meso-epithermal type, with main mineralization epoch in Caledonian. Based on the analysis of the metallogenic geological conditions, geological features and ore-controlling factors of the deposit, with geophysical and geochemical survey results, it is concluded that the deep of the orefield has a good prospecting potential.
