六十年代以来,国内外对包裹体内微量气相成分和同位素组成进行了大量分析工作,对于探讨原始成岩成矿溶液的物质成分、矿床成因、成矿阶段演化以及成矿物质来源等起了重要的推动作用。本文使用-1305质谱计对矿物包裹体内气相成分进行了初步分析,它与常用的气相色谱法比较,具有灵敏度高、能同时作多种成分的检测、定性结果好等优点。
Since the 1960s, a great deal of analysis has been done on trace gas components and isotopic composition in the inclusions at home and abroad, which plays an important role in exploring the composition of the original diagenetic ore-forming solution, the genesis of the deposit, the evolution of the ore-forming stage and the source of metallogenic materials Promote the role. In this paper, the composition of gas phase in mineral inclusions was first analyzed by -1305 mass spectrometer. Compared with common gas chromatography, it has the advantages of high sensitivity, simultaneous detection of multiple components and good qualitative results.
