GIS在阿尔金成矿带铜矿成矿预测中的应用

GIS application in the metallogenic prediction of copper deposit in the Altyn Tagh metallogenic belt, China

在野外地质调查和室内综合研究的基础上,通过地质、地球化学、地球物理等成矿地质背景研究,应用GIS软件建立了基础数据库。利用非线性矿产资源评价模型和MRAS等软件叠加分析,对阿尔金成矿带铜矿进行了成矿预测,证明基于GIS的成矿预测是行之有效的,为本区成矿规律研究提供了更多重要的找矿信息和方法。

Based on the field geological survey and indoor integrated study, combined with geological, geochemical and geophysical studies, the authors used GIS softwares to set up a basic database, and the nonlinear mineral resources evaluation model and stacking of MARS and other softwares to conduct the metallogenic prediction of copper deposits in the Altyn Tagh metallogenic belt. It is proved that the metallogenic prediction based on the GIS is effective. It may provide more and important ore search information and methods for the metallogenic study in the area.
