中文摘要:文章在对研究区内的地、物、化、遥及重砂等信息与铅锌成矿的关系进行深入分析的基础上,分别建立了甘肃临潭—宕昌地区铅锌矿床远景区两种主要类型矿床的找矿信息综合模型。在MORPAS平台上,利用GIS的空间信息技术,从模型中优选出20个有利铅锌成矿的地质变量对本区铅锌矿床进行了预测,圈定出了两级找矿远景区。 |

Abstract:This paper deals mainly with the application of GIS technique to the integrated analysis of multi-information ore prognosis and the evaluation of the lead-zinc prospect district in Lintan-Dangchang area. The authors probed into the relationship of geological, geophysical, geochemical, remote sensing and heavy mineral information to lead-zinc mineralization and established integrated models for the prospecting of two major types of ore deposits. On such a basis, 20 favorable variables were chosen according to the models, and lead-zinc prospect districts in Lintan-Dangchang area were delineated through spatial analysis of the MORPAS system. The results obtained provide powerful evidence for ore prospecting and greatly raise the precision of ore prognosis. |
