MAPGIS空间分析在瓦恰地区以Cu、Pb、Zn为主成矿预测中的初步应用

工作区位于木吉—阿克赛钦Cu、Au(Fe)成矿带北部,优越的地质、构造、地球化学条件,孕育了丰富的铜、铅、锌矿产。笔者应用国内MAPGIS系统平台,运用其矢量空间分析模块,对研究区多源信息(地、物、化信息)进行迭加、分析、统计,总结了成矿地质条件和找矿标志,对成矿最有利区域进行预测,圈定了成矿远景区。

THE PRIMARY APPLICATION OF MAPGIS SPATIAL ANALYSIS ON COPPER,LEAD AND ZINC METALLOGENIC PROGNOSIS IN THE WAQIA AREA

Located in the north of the Muji-Akesaiqin mineralization zone,the working area is quite rich in copper,lead and zinc minerals.Geologically,the structures and geochemistry conditions are excellent.Applying the vector spatial analysis module of the famous domestic GIS software and MAPGIS system,the multi-information(geology,geophysics and geochemistry) of the area is superposed,analyzed and counted in the paper.We successfully summarized the metallogenic geological conditions and the indicator,predicted the favorable metallogenic zone,and summarized the experience of using MapGIS system for metallogenic prognosis.
