摘要/Abstract

摘要： 在内蒙古兴安盟科右前旗胜利屯开展了找矿工作，在地表共圈定多条以Ag，Cu为主的矿（化）体。各矿（化）体均产在花岗闪长岩体内北西向次级断裂破碎带中，与花岗斑岩空间关系密切。钻孔中各类岩石地球化学数据统计分析表明Ag，Cu等元素在花岗闪长岩中较其它岩类富集，在破碎带中最为富集，初步认为该矿床属构造破碎带热液蚀变型银铜多金属矿床。

Abstract: Through carrying out prospecting work in Keyouqianqi Shengli town of Xing'anmeng,the surface is delineated as numerous Ag and Cu-based ore-bodies. All ore-bodies are produced in secondary north-west faults fracture zone of granodiorite, which are closely related with granite porphyry. Various geochemical data statistics of rocks in drillings show that Ag, Cu and other elements are enriched in granodiorite rather than other rocks, and mostly enriched in the fracture zone. It is thus concluded that the deposit belongs to the silver-copper polymetallic deposit with hydrothermal alteration type in the fracture zone.

Key words: Rock geochemistry, Hydrothermal alteration type, Silver-copper polymetallic ore, Daxing’anling ore belt
