摘要
文章在构建张八岭隆起北段地质、地球物理和地球化学数据库的基础上,建立了较为详实的地质-地球化学空间信息结构模型;利用MORPAS3.0软件中常用的证据权重法,从地层、构造、岩浆、地球化学4个方面优选找矿标志,并开展了金矿找矿远景区预测和找矿靶区的优选。按照成矿地质条件的优劣程度、金矿床(点)的空间分布、金矿化的直接标志与间接标志、地质研究程度、示矿异常程度等因素的不同,把找矿靶区划分为3级8个区域。
Database of geology,geophysics and geochemistry of the north Zhangbaling uplift is built then the spatial model of geological and geochemical information.Software MORPAS 3.0 (weights of evidence) is used to optimize prospecting marks in respects of stratigraphy,tectonics,magmatism and geochemistry and Au prospects and targets.According to metallogenic condition,spatial distribution of the Au deposits and occurrences,direct and indirect marks of Au deposit,availability of geological data and degree of ore indicated by the anomlies 8 targets of 3 classes are put forward.
