摘要
以金龙山—丘岭金矿床为例,通过对发育在容矿层上的构造类型与其上封盖层岩性类型进行研究,划分出9种构造与盖层岩性组合类型,并分析其对含金热液的控制,总结出中-低温热液卡林型金矿床富集规律:Ⅰ型组合发育区容矿层的含矿液性最好;Ⅲ,Ⅵ,Ⅸ型组合发育区容矿层的含矿液性最差;Ⅱ,Ⅳ,Ⅴ,Ⅶ,Ⅷ组合发育区容矿层含矿液性较好。最后提出了在金龙山外围有望找金区域。
The paper deals with the cover rock lithology-the host rock structure combination control on ore fluid in Jinlongshan Au deposit. The combination is divided into 9 types and their controls on trapping ore fluid are analysed. Au concehtration pattern of medium-low hydothcrmal Clarlin type Au deposits are summed up. The trapping of combination Ⅰis the best, the trapping of combination Ⅱ ,Ⅳ,Ⅴ, Ⅶ,Ⅷbetter, the trapping of combinationⅢ, Ⅳ, Ⅸ the worst. Based on this targets in the surroundings of Jinlong Au deposit are pointed out.
