| 摘 要： | 矿物沸腾包裹体是矿液处在沸腾相态下被矿物捕获的包裹体,它具有不同形态、不同大小、不同类型混乱产出的特征,包裹体溶液含盐度高,均一温度变化大,有些包裹体可能含有围岩碎屑。温度、压力、盐度是影响矿液沸腾的因素。研究沸腾包裹体有助于研究矿床形成的地质条件和矿液运移方式,可提供找矿信息。均一温度用所测数据两极值或中值作为成矿温度均不恰当,应以均一温度最小的液、气相包裹体的均一温度作为试样所在处的成矿温度较为适宜,成矿压力亦采用这种包裹体所测得的压力值作为代表较为恰当。

| Abstract: | The boiling inclusion means those which were incorperated into minerals when fluid were in the boiling state. They are characteristic of mixtural occurrence of various shape, different size and type of inclusions, with high salinity of its solution, great changes in homogeneous temperature,some of which may contain fragments from country rocks.Temperature, pressure and salinity are factors influencing the boiling of fluid. The study of boiling inclusion is helpful for understanding the geologic conditions of formation of deposit and the mode of migration of fluid, and also provides information for exploration. It is not appropriate to take the maximal, minimal or medium measurements of homogeneous temperature as ore-forming temperature. It is advisable to use the minimal homogeneous temperature of liquid,gas phase inclusion as ore-forming temperature where samples were taken, and ore-forming pressure could also be represented by the pressure value measured from this kind of inclusions. |
