岩浆岩的侵位和结晶作用是组成地壳的主要方式, 对地球化学环境及成矿作用具有决定性影响。本研究利用岩石学、地球化学和矿物学的方法, 深入探讨了矿区成矿作用与岩浆岩之间的复杂关系。研究发现, 岩浆岩体通常代表了深部地球物质与地表环境的物质交换, 并且在成矿作用中起到集矿和输送矿质元素的双重作用。此外, 岩浆岩中的微量元素、稀土元素及放射性元素的赋存状态, 也为追踪成矿流体来源及演化提供了重要线索。基于岩浆岩与成矿作用的研究, 进一步探讨了侵入作用、结晶分异、矿物赋存状态等因素对金属矿物成矿潜力的控制机制, 并在此基础上, 根据岩石类型、岩浆成分以及侵位深度等参数建立了一套系统的成矿预测模型。研究表明, 成矿作用与岩浆活动之间存在着密切的时空联系, 成矿元素的迁移分布与岩浆岩体的构造位置、侵位深度、岩体形态和岩浆演化阶段等因素密切相关。通过对比分析不同地质背景下岩浆岩与金属矿床的关系, 揭示了矿区成矿作用的规律及成矿地质背景, 填补了岩浆岩与成矿作用研究领域的空白, 对于未来矿产资源的勘探与评价具有重要的实际意义。岩浆岩的不同类型和成矿作用的关系, 矿区成矿作用的分类与评价, 以及成矿作用的时空分布规律, 为矿产资源的发现和利用提供了科学依据和新的研究方向。本研究结果可为相关领域提供理论参考, 并为矿产资源勘探提供新的思路。

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.
