Temporal and Spatial Correlation Analysis of Mineralization during Magmatic Hydrothermal Activity Evolution

The emplacement and crystallization of magmatic rocks are the main ways of forming the crust, which have a decisive influence on the geochemical environment and mineralization. In this study, the complex relationship between mineralization and magmatic rocks is deeply discussed by using petrology, geochemistry and mineralogy methods. It is found that magmatic rock mass usually represents the exchange of deep earth materials with the surface environment, and plays the dual role of collecting ore and transporting mineral elements in the mineralization process. In addition, the occurrence states of trace elements, rare earth elements and radioactive elements in magmatic rocks also provide important clues for tracing the source and evolution of ore-forming fluids. Based on the study of magmatic rocks and mineralization, the controlling mechanism of intrusion, crystallization differentiation and mineral occurrence on metallogenetic potential of metal minerals is further discussed. On this basis, a set of systematic metallogenic prediction model is established according to the parameters of rock type, magmatic composition and emplacement depth. The results show that there is a close spatiotemporal relationship between mineralization and magmatic activity, and the migration and distribution of ore-forming elements are closely related to factors such as the tectonic location, emplacement depth, rock mass morphology and magmatic evolution stage. Through comparative analysis of the relationship between magmatic rocks and metal deposits under different geological backgrounds, the regularity and metallogenic geological background of the mining area are revealed, which fills the gap in the research field of magmatic rocks and mineralization, and has important practical significance for the exploration and evaluation of mineral resources in the future. The relationship between different types of magmatic rocks and mineralization, the classification and evaluation of mineralization in mining areas, and the spatio-temporal distribution of mineralization provide scientific basis and new research directions for the discovery and utilization of mineral resources. The results of this study can provide theoretical reference for related fields and provide new ideas for mineral resource exploration.
