摘要
应用地理信息系统(GIS)技术,深入地研究了云南澜沧江流域成矿的建造和构造,划分出不同级别的地质异常单元和有利成矿的断层影响带;分析了化探异常与相关矿床的耦合度和出现率;系统地总结了已有矿点资料,建立了矿产资源潜力评价空间分析模型.在上述研究基础上作出该地区有色、稀有、贵金属资源潜力图,对资源潜力作出评价。
This paper applies the techniques of GIS to the comprehensive appraisal for mineral roources in the Lancangiiang River region. Deep study on the formation and construction of ore-forming zones is carried out, which leads to the delineation of different levels of geological anomaly units and fault-buffer zones that are favorable to ore-forming; the inter-relationship between geochemical anomalies and deposits in the Lancangiiang River region and the probability of deposit occurrence within thOSe anomaly areas are analyzed;the spatial analysis model for mineral resources potential assessment is established based on the systematical analyzing the discovered ore occurrences. Based on all these analysis, the mineral resources potential rnap has been charted out which includes nonferrous, rare and precious metals, and the mineral resources potential of this region is also evaluated.
