| 摘 要： | 在对云南哀牢山成矿带地质特征研究的基础上,借助GIS空间分析功能,对哀牢山成矿带南段金矿控矿因素进行了分析,建立了金矿信息找矿模型.结果显示:金矿受NW向断裂构造控矿明显,在其周边3 km范围内是本区有利的找矿远景区;与岩浆岩关系密切,岩体在很大程度上控制了金矿床(点)的产出;与地层关系差;区内地层和岩浆岩可能为金矿提供了物源,与金矿关系最为密切的元素化探异常有Au、Ag、Cu、Pb、Bi. |

| Abstract: | Based on geological features of Ailaoshan metallogenic belt,the ore-control factors are studied by space analysis technology of GIS softs,with which the gold deposits exploration model is proposed.It is indicated that gold deposits in Ailaoshan metallogenic belt are controlled by NW trending faults,forming a favorable exploration target of 3 km zone from the faults.Gold mineralization is related to igneous rocks which determine the occurrence of gold deposit to a large extent.The gold mineralization is poorly related to strata, but the strata,as well as magmatic rocks,may provide source of Au for the gold deposits.Geochemical anomalies,such as Au,Ag,Cu,Pb and Bi,are closely related to gold mineralization. |
| Keywords: | geographic information system(GIS) ore-control factors gold deposit southern Ailaoshan metallogenic belt |
