利用GIS编制矿产预测图

GIS TECHNIQUE USED FOR MAKING OF MINERAL RESOURCES PREDICTION MAP

介绍了GIS(地理信息系统 )在矿产预测图编制中的应用、工作原理 ,并以澳大利亚YilgarnBlock矿区金矿预测的成功实例说明GIS在矿产预测图编制中的主要步骤。

We benefit from GIS in collecting, editing, modify ing and analysing data. It can analyze, confirms quantifies the space relations to mineralization and integrates these relations into a prospecting map. It can help us to refresh data, make the variation of analysis and modify the pattern of map during the process of making a prospecting map. Based on the analysis of its characteristics, the application and principle in the mineral resources map-making process in the Yilgarn Block gold mine are detailed.
