Abstract
Yunnan Dahongshan Copper Mine is one of the largest copper mines in Yunnan Province with an important economic value. Based on the spatial-temporal evolutionary structure and metallogenic characteristics of the Dahongshan Copper Mine, this paper studied the geological conditions, rock characteristics and ore geochemical characteristics of the Dahongshan Copper Mine. The results have shown that the basalt has highly consistent geochemical characteristics, while the geochemical characteristics of rocks and granites are island arcs. The geochemical analysis of rare earth elements in the mining area indicates that the mining area possesses sedimentary characteristics, and skarn enriches iron elements and supplies iron elements such as pyrite in the mining area. The metallogenetic genesis of the mine indicates that the mineralization of the mining area involves multiple phases and multiple stages, including the sedimentation of the sedimentary rocks in the Hercynian period and the laminar filling of the magmatic rocks. The research results can provide a reference for the structural environment, the metallogenetic genesis, and the prospecting direction of the deposit.
