摘要
流体熔融包裹体是一种新类型,它代表岩浆分异热液的过程。 按室温时的相态和成分可分四种:1.气相+液相+熔体相的流体熔融包裹体;2.熔融包裹体与流体包裹体共存;3.熔融包裹体周围有细小的流体包裹体群;4.含易溶盐子矿物+气相+熔融体的流体熔融包裹体。
Fluid-melt inclusions arc a new type which bears information on the process in which hydrothmnal fluids were differentiated from the magma. They contain both silicate melt and fluid- Four types are distinguished: 1. melt inclusions with liquid and gaseous phases; 2. melt inclusions coexisting with fluid inclusions; 3. melt inclusions surrounded by tiny fluid inclusions; and 4. melt inclusions with soluble daughter minerals and vapor. Compositionally, such fluids can be divided into three types: brine, CO2 fluid and sulfide globule. Fluid-melt inclusions are of significance not only in geological theory but also in exploring oreforming processes.
