目前激光拉曼探针直接测定抛光片中矿物单个包裹体气液相组分 ,所获得的是分子团相对摩尔分数 ,而不能获得包裹体中流体的阴、阳离子和成矿元素组分 ,因此群体包裹体成分分析仍然是进行矿床地球化学研究、获得成矿流体有关信息的首选方法。矿物群体包裹体成分分析 ,除要求样品必须是纯净的单矿物 ( 99%以上 )外 ,还要了解样品中原生和次生包裹体的含量、特征、大小、气液比以及它们各自的均一温度、爆裂温度和盐度等情况 ,以便确定样品合适的粒径 ,剔除次生包裹体和打开原生包裹体的爆裂温度等。然后采用热爆法 ,打开原生包裹体 ,用不同的方法测定其各种成分 ,从而获得成矿流体成分的可靠信息。
The laser Raman probe is currently used to directly measure the gas-liquid components of single inclusions in polishing films, and the relative molar fractions of molecular clusters are obtained, but the anion, cation and ore-forming element components of fluids in the inclusion are not obtained. The composition analysis of group inclusions is still the first choice for studying the mineralization of ore deposits and obtaining the information about ore-forming fluids. In addition to the requirement that the sample must be a pure single mineral (99% or more), the composition analysis of mineral hermaphrodites requires that the content, characteristics, size, gas-liquid ratio, and their respective homogenization temperatures of the primary and secondary inclusions in the sample , Burst temperature and salinity, etc., in order to determine the appropriate particle size of the sample, excluding secondary inclusions and open the original inclusion burst temperature and so on. Then the thermal explosion method was used to open the primary inclusions and determine their various compositions by different methods to obtain the reliable information of the ore-forming fluid composition.
