以泰国铜金热液型矿区为例,根据地质异常理论、典型铜金矿成矿模式,利用ETM+遥感影像、地质图、矿产地质数据库等多元地学数据,结合GIS技术,提取研究区地质(地层、构造)、遥感(羟基、铁染蚀变信息和线环构造)等致矿信息,采用证据权法对该区铜金矿进行成矿预测,并结合研究区主要控矿地质要素,圈定研究区铜金找矿有利地段,为该地区的找矿工作提供参考。
以泰國銅金熱液型礦區為例,根據地質異常理論、典型銅金礦成礦模式,利用ETM+遙感影像、地質圖、礦產地質數據庫等多元地學數據,結閤GIS技術,提取研究區地質(地層、構造)、遙感(羥基、鐵染蝕變信息和線環構造)等緻礦信息,採用證據權法對該區銅金礦進行成礦預測,併結閤研究區主要控礦地質要素,圈定研究區銅金找礦有利地段,為該地區的找礦工作提供參攷。

Geological information quantitative integration research is the frontier and hotspot of prospecting decision research in the world. The formation process of the large Cu-Au deposit is influenced by complicated geological events and restricted by various geological factors, such as strata, structures and alterations. In this paper, with the copper-gold ore district in Thailand as the study ob?ject, on the basis of geological anomaly theory and typical copper and gold metallogenic model, ETM+remote sensing images, geolog?ical maps and mineral geology database in the study area, and in combination with GIS technique, the authors extracted the ore-forming information in this area such as geological information (strata, linear-circular faults, intrusions), remote sensing information (hydroxyl alteration, iron alteration, linear-circular structure), and delineated the Cu-Au prospective targets by using weights of evi?dence model. The research results show that the remote sensing and geological data can be combined to perform quick prediction and assessment in search for mineral resources in this metallogenic belt.
