认为该矿床是在岩浆水和后期少量大气水的加入而形成的混合热液共同作用下,活化碳酸盐岩地层和石英闪长岩中的铜等成矿元素,形成含矿热液,并以铜的氯络合物方式运移,在弱还原性条件下使原始沉积矿胚层加厚变富。

The metal elements of the volcanic-hosted massive sulfide deposit have two sources, the copper and zinc are derived from rhyolitic magmas whereas the lead are probably related to old sediments overlying the rhyolites.(4) It is suggested here that the volcanic rocks hosting massive sulfide deposit in the north Qilian orogen, which are previously considered as a bimodal suite of Neo-proterozoic to middle Cambrian age in a continental rift, are virtually related to subduction magmatism in Ordovician age, and there might have no continental rift magmatism of Neo-proterozoic to middle Cambrian in the north Qilian.

Th/Ta比高(5.0~11.7),εNd为较大的负值(-2.6~-8.4),流纹岩的形成可能是两个端元组分混合的过程、或是上地壳混染的结果,形成在活动陆缘环境;(3)北祁连块状硫化物矿床成矿金属物质具有两种来源,Cu、Zn等来源于流纹岩,而Pb的来源可能与古老沉积物有关;(4)本文认为,前人厘定的北祁连新元古代-中寒武纪赋存块状硫化物矿床的大陆裂谷双峰式火山岩应是与俯冲作用有关的奥陶纪火山岩,说明北祁连可能不存在新元古代-中寒武纪的大陆裂谷活动。

Each type can be subdivided into several kinds: textural mixing deposits include rocks mainly composed of terrigenous components and rocks that mostly consist of intrabasinal composition.
