The origin of metallogenic hydrothermal fluids was studied through simulating REE pattern of the balanceable hydrothermal fluids. The results indicate that the metallogenic materials come from the diorite and the metallogenic hydrothermal fluids come from the dioritic magma. The results also show that the rare earth elements are relatively mobile during metallization.展开更多

The models were established based on practical data of the polymetallic deposits dominated by copper ore in southeastern Hubei. These models, which are graphically illustrated in the paper, systematically summarize the metallogenic geological conditions and the geophysical-geochemical characteristics of copper deposits in this area. The models are of practical significance for studying copper deposits, predicting mineral resources, choosing exploration methods, and searching for ore deposits based on existing ones in the study area.展开更多
