滇西北衙金矿床找矿标志和找矿模式研究

The prospecting mark and mode of Beiya Gold Deposit in Western Yunnan

北衙金矿床位于扬子准地台与三江褶皱带的接合部位。本文在前人工作的基础上 ,全面研究了其地质、地球物理、地球化学和遥感影像等找矿标志 ,总结出的找矿模式为 :物化探扫面→追斑岩带→寻次级断褶构造→查物化探异常→定包络脉体→探原生矿体及其次生矿体。由于该类型矿床无论在北衙地区还是在区域上都很有代表性 ,所以研究成果不仅可以指导区域上寻找类似矿床 ,而且可为北衙金矿资源的找矿勘探提供科学依据。

Beiya gold deposit is situated in junction place of Yangzi metaplatform and Sanjiang fold belts On the basis of predecessors works,this paper has comprehensively researched the prospecting mark of Geology, Geophysics, Geochemistry and remote sensing image etc.The mode of prospectiong is summed up as geophysical and geochemical exploration within the area given→seeking prophyry belts→looking for secondary fault fold strueture→checking the anomaly of geophysical and geochemical exploration→setting enveloping orebody→exploring primary and secondary orebodies Due to this type gold deposit has more representativeness both in Beiya area and in overall regions,the achievements in scientific research not only can guide to prospect the similar deposits but also can provide scientific basis for prospecting and exploration of Beiya gold deposit resources
