成矿过程中流体的作用及其主要研究方法

THE ROLES OF FLUID IN THE FORMATION OF ORE DEPOSITS AND THE MAIN STUDY METHODS

流体在成矿过程中扮演着十分重要的角色,它是成矿物质得以活化、迁移、富集的主要介质,同时流体的运移还能扩展有利的成矿空间。同位素地球化学方法仍然是成矿流体研究的主要手段,实验地球化学、元素地球化学以及现代岩石学和矿物学研究方法在探讨流体的起源、演化等方面已发挥越来越重要的作用。每种方法均有其局限性。

Fluid plays an important role in the forming process of ore deposits, and it is also a fundamental medium for the mobilization, transportation and enrichment of ore forming elements, which are very critical for the formation of ore deposits. Furthermore, many beneficial ore forming spaces are produced during the transportation of fluid. Taking ore forming fluid as the main thread, this paper introduces the latest development of the studies on the roles of the ore forming fluid in the forming process of ore deposits and reviews the main study methods. The isotopic geochemistry method is still a very useful one in the study of the ore forming fluid, and the methods of experimental geochemistry, elemental geochemistry and petrology &mineralogy are also becoming more and more important. However, each method has its own deficiency, and it is necessary to combine these methods together in the practical research.
