摘要
四极质谱法测定的爆裂温度曲线,可区分出不同成矿阶段群体包裹体温度区间,并分别测定其气相组成。代表不同成矿阶段的包裹体气相组成有明显差异。本研究表明用四极质谱法测定同一样品中不同成矿阶段的包裹体气相组分是可行的,拓宽了成矿流体研究的思路,为研究多期次成矿流体的来源、演化和解译矿床成因提供了新的方法、手段。
It can be distinguished the temperature range of cluster inclusions from different mineralization stages and can be measured their gaseous composition for burst temperature curve determined by Quadrupole Mass Spectrometer. Various gaseous composition of fluid inclusion represents different mineralization stages. This study concluded that it is feasible for Quadrupole Mass Spectrometer to determine the gaseous composition of fluid inclusion from different mineralization stages in one sample. Hence, it would be widened the researching way and wishes to provide a new method for investigating the origin and evolution of multi-stage ore-forming fluid and interpreting the genesis of deposit.
