Abstract

Abstract

Chengmenshan ore field is located in the middle part of Middle-Lower Yangtze River Cu-Fe mineralization belt, China. It is a large comprehensive ore field with enriched in ore-forming elements of Cu, S, Pb, Zn, Mo, Au, Ag and Fe. The deposit is a trinity of massive sulfide-type, skarn-type and porphyry-type. Massive sulfide-type ore body is the largest one in the Chengmenshan ore field, and it accounted for 57% of total copper resources. Based on the investigation on geological characteristics, thickness and grade changes of ore body along the strike and tendency, it summarized the features of mineralization. It studied and discussed the controlling factors of mineralization enrichment about ore-forming temperature and geochemistry, genesis of mineral deposit, prospecting direction of the mine periphery. The mineralization of the orebody has zonality both horizontal and vertical direction. It roughly shows Mo, Cu, Zn, Pb, Ag, Au element mineralization zonality from hydrothermal center to outside, and TFe, Au, Ag, Pb, Zn, Cu element mineralization zonality from surface to down. In addition, the mineralization is different. It display inconformity both the ends of the orebody along the strike and leguminous shape along the tendency. In this paper, the zonality and difference mineralization identified the hydrothermal genesis and sedimentary origin respectively. It has preferable exploration prospect outside the orefield, especially the eastern periphery of mine.
