摘要
多铎金铜矿位于智利著名的白垩纪斑岩铜矿带上,同时也属于前海岸山IOCG成矿带,矿区周边分布着多个大型的斑岩型和IOCG铜矿、铜金和铁矿矿床。通过对矿区地质特征、物化探异常、矿石矿物及工程验证成果综合研究,总结矿床成因,提出找矿思路及找矿标志。
Duoduo gold copper deposit is located in the west side of the Cretaceous porphyry copper belt in Chile,which belongs to the IOCG metallogenic belt of the Front Coast Mountain.There are many large porphyry deposits and IOCG copper,copper gold deposits and iron deposits around the mining area.Based on the comprehensive study of the geological characteristics,geophysical and geochemical anomalies,ore minerals and engineering verification in the mining area,this paper has summarized the deposit genesis,and has also pointed out the prospecting idea and indicators.
