| 中文摘要: |
| 文章利用Morpas软件对甘肃省白银厂矿区内的地、物、化等多源信息进行统计分析,提取了成矿有利信息,认为成矿有利地层为石英角斑凝灰岩系,成矿有利构造为火山机构及背斜构造,成矿有利岩体为石英钠长斑岩岩体。采用证据权重法对研究区圈定了成矿预测和找矿远景区,并指出了找矿方向。 |
| 英文摘要: |
| According to metallogenic geological analysis of Baiyinchang district in Gansu province, statistical analysis and metallogenic favorable information extraction of geological, geophysical and geochemical data were carried out on the platform of Morpas. The metallogenic favorable evidences layers are quartz-keratophyric tuffs series, volcanic edifice, anticlines and quartz albitophyre. By the weight of evidence we delineated the prospecting areas. |
