摘要
查明地质异常是成矿预测的基础、找矿的前提、靶区圈定的依据。本文以"三联式"成矿预测理论为指导,着重探讨了甘肃省铅锌矿地质、地球物理以及地球化学异常的识别、提取与圈定,运用定量分析方法,厘定地质异常与铅锌矿种之间的关联,在此基础上,运用证据权成矿预测方法实现对甘肃省铅锌矿床的成矿定量预测及成矿远景区圈定。
Geoanomalies are essential for mineral resources prediction, ore search and target determination. Guided by the ＂Three Components Predic- tion Theory＂, this paper addresses the following issues： identification, extraction and delineation of geological, geophysical and geochemical anomalies, and using quantitative analysis methods to determine correlations between geoanomalies and various kinds of lead-zinc ore deposits. Then, in terms of the mineralization prediction method based on evidence weights, this work makes quantitative prediction of mineralization and determination of prospective are- as of lead-zinc deposits in Gansu Province.
