证据权重法在虹螺山——五指山地区铅锌成矿预测中的应用

Application of the weight evidence method of lead-zinc metallogenetic prospecting prediction in Hongluoshan～Wuzhishan region

根据虹螺山-五指山地区铅锌成矿地质特征,建立研究区综合地质数据库,提取了13个有利成矿的证据权因子,以证据权重法为预测方法对该区进行成矿远景预测,最终划分了三个远景区级别,圈定出十三处成矿远景区,其中三处远景区内尚未发现铅锌矿产地。

According to the geological characteristics of mineralization of lead - zinc mineralization in Hongluoshan-Wuzhishan area,established the spatial database of the predicted area, as well as extracting thirteen favorable ore-forming factors, apply the weight evidence method to simulate the general-information evaluation of the predicted area. Determined three Prospective levels, delineated thirteen Prospective areas,three of which have not been found any mineral deposits by now.
