摘要
根据秦岭地区铅锌矿床成矿地质背景,应用Arcview GIS对赋矿地层、控矿构造等进行空间分析,提取预测变量。依据不同预测变量与铅锌矿床的相关性大小,选择不同的模糊算子进行综合,生成识别控矿因子。参考伽马算子、综合控矿因子,进行成矿远景区划分,并依据伽玛算子大小进行靶区优选。
Based on analysis of the geological background of Pb-Zn deposits in Qinling region. ArchView GIS was applied to analyzing spatial relation of the ore host stratum, ore-controlling structure and extracting the ore predicting variables. According to the correlative degrees of the variables and the deposits various fuzzy operators were selected to synthesize, generate and recognize ore-control factors. Gamma operator and the synthetic ore-control factor were referred to division of the potential areas then the target areas were optimized by size of Gamma operators.
