地质学家对岩浆的流体饱和状态特别感兴趣,这是由于在岩浆体系中自由流体相的存在是引起和控制很多岩石成因作用的重要因素。其中,如岩浆交代和变岩浆作用、射气分异作用和岩浆派生的含矿溶液的形成等现象,都与流体的热量转移和物质转移有关。由此可见,扩大和确定关于流体饱和岩浆所具有的天然乳浊液的特征和性质方面的知识是非常必要的。研究岩浆岩矿物中的包裹体有可能达到此目的。因为从具有乳浊液结构的介质中生长的矿物,以原生包裹体的形式既能捕获分散介质(熔融体),又能捕获分散相(流体)。从“沸腾”溶液中培养晶体的实验,以及天然岩石的气热地球化学研究成果,都证实了这一点。例如,在
Geologists are particularly interested in the fluid saturation of magmas because the presence of a free-fluid phase in the magma system is an important factor that causes and controls the genesis of many rocks. Among them, phenomena such as magmatic metasomatism and magmatic alteration, gas differentiation and the formation of magma-derived ore-bearing solution are all related to the heat transfer and material transfer of fluid. From this it can be seen that it is necessary to expand and determine knowledge about the characteristics and properties of natural emulsions possessed by fluid-saturated magmas. The study of inclusions in magmatic rocks and minerals may achieve this goal. Because minerals grown from a medium with an emulsion structure capture both the dispersion medium (melt) and the dispersed phase (fluid) in the form of primary inclusions. This is confirmed by experiments in the crystallization of “boiling” solutions, as well as in the geothermal geochemical studies of natural rocks. For example, at
