滇东南地区为云南省重要的钨、锡、银、铜、铅、锌等矿产基地.自西向东分布着个旧岩体、薄竹山岩体和老君山岩体。薄竹山岩体形成于晚白垩世,分布面积约120km2,其边缘地带是寻找大、中型钨锡多金属矿床的有利靶区;经过近几年地质勘查工作,在其周边发现一些小-中型的矽卡岩矿体,以铁、铜、锡、钨为主,伴生铅、锌、银等。矿体分布明显受区内特定的地层、岩体、构造等成矿条件制约。本文试图通过对该区地质特征、物化探信息特征进行综合和分析,评价区内的找矿潜力。
Southeastern Yunnan is an important mineral base of tungsten, tin, silver, copper, lead and zinc in Yunnan Province, with Gejiu rock mass, thin-bamboo rock mass and Laojunshan rock mass distributed from west to east. The thin-grained pluton was formed in the Late Cretaceous with a distribution area of about 120km2. Its marginal zone is a favorable target for finding large and medium-sized tungsten-tin polymetallic deposits. After geological exploration in recent years, some small-medium sized Skarn ore body, iron, copper, tin, tungsten-based, associated lead, zinc, silver and so on. The distribution of ore bodies is obviously restricted by the metallogenic conditions such as strata, rock mass and structure in the area. This article tries to evaluate the geological prospecting potential in this area through the synthesis and analysis of geophysical and geochemical information features.
