东昆仑哈日扎斑岩型铜矿床特征及成因探讨

The characteristics of the porphyry copper deposit and its formation in the East KunLun Harizha area

通过对哈日扎地区斑岩型铜矿床特征、岩石特征的阐述,和对蚀变分带、成矿期次的划分以及矿床成因的探讨;认为斑岩成矿事实明显,找矿前景较好;矿化主要赋存于具硅化、绢英岩化蚀变的岩石中;矿体的产出有两种方式;斑岩体来源于地壳物质,成矿物质的来源为地层或蚀变的硅质洋壳重融。

The petrographic and mineral characteristics of the porphyry copper deposit were elaborated in Harizha area.The alteration zoning,metallogenetic stage and genetic type of mineral deposit were also analyzed.The plain fact is that porphyry copper deposit and has the prospects of prospecting.The main mineralization is concentrated in the alteration rock of silicified and beresitizationed.The occurrence of the ore bodies is usually in two different patterns.The porphyry bodies derived from the crustal materials while the ore materials derived from the stratum or the remelt of altered and siliceous oceanic crust.
