摘要
More attention has been paid on the study of the mineralization and alteration in Zijinshan Cu-Au deposit in recent years,less involved in the importance of the vertical zoning features of the copper minerals.This paper mainly study on vertical features of distribution and variation of the copper minerals in Zijinshan Cu-Au deposit,aims to analyze the deposit genesis,and expect to guide the prospecting of the deep orebody.With the electron microprobe test and mineralographic microscope testing,from top to bottom in original layered system sampling of 6 drillings recent exploration in the deposit got 72 polished section,which were identified with ore microscope,and 50 of them in electron microprobe analysis,basically clarified the main copper mineral zonation characteristic and the change regularity of Mo content,then analyze the generation of physicochemical conditions of main copper minerals further.It is believed that the deposit is the same tectonic-magmatic-metallogenic system products,but obviously controlled by the deep magma evolution phase,thus forming a stacking pattern that the upper is epithermal metallogenic system,the lower is porphyry metallogenic system.So we deduce that the porphyry copper molybdenum ore bodies is present in the deeper part.
