摘要
本文通过对辽西八家子地区区域地质背景、地球物理、地球化学、围岩蚀变等成矿特征的分析,并根据各证据因子建立相关有利证据层,在GIS平台下采用证据权重法技术对研究区钼矿进行成矿预测,圈定了有利成矿部位,为下一步找矿工作提供依据。
Through analysing the ore -controlling factors of Bajiazi area,such as areal geology background,physical geography,geochemisty,wall -rock alteration.etc,the evidence factors are fixed and benificial prool layers are founded.Then, the author adopts the weights of evidence to prodict the Mo-deposits’ formation based on GIS ,and delineate the beneficial metallogenic position to conduct the next geophysical exploration.
