查干德日斯铜多金属矿床地质特征

Geological Characteristics of the Chaganderisi Copper Ploymetallic Deposit

内蒙古阿拉善左旗查干德日斯铜多金属矿床为在2013年航磁异常查证过程中被发现,矿体赋存于中-上太古界多期次变形的深变质岩系中,矿体和蚀变带分布明显受断裂控制。在对矿区地质特征、矿体特征分析的基础上,对矿床成因进行了讨论,认为矿床成因类型属晚古生代中低温热液充填交代型,成矿元素以Cu为主,Ag、Au、Pb等为伴生元素。

The copper-gold ploymetallic deposit in Chaganderisi is the ore-searching prospecting ar- ea that found out during the aeromagnetic anomaly inspection in 2013. The orebodies are hosted in MesoNeoarehean deep metamorphic rock series that undergone multi-deformation, the orebodies and alteration belts are controlled by fault structure obviously. Based on the analysis of geological features of the mining area and the ore deposit geological characteristics, the genesis of the mineral deposit is discussed, the re- sults show that, the genetic type of the copper-gold ploymetallic deposit in Chaganderisi belonged to me- dium-low temperature hydrothermal filling-metasomatic deposit, Cu is the main ore-forming element, Ag, Au, Pb etc are the associated elements.
