嵩溪银(锑)矿是一个新发现的大型独立银矿。矿物流体包裹体超高真空四极气相质谱系统测定显示,该矿成矿流体中存在多种轻烃有机气体,主要由C_1—C_4饱和烷烃组成,仅含微量C_2—C_4不饱和烯烃和芳烃,说明成矿过程基本未受到高温岩浆作用的影响。化学平衡研究表明,这些轻烃气体为微生物成因和沉积岩围岩中Ⅱ类干酪根热解成因的混合气
Songxi silver (antimony) mine is a newly discovered large-scale independent silver. The determination of mineral fluid inclusions by ultra-high vacuum gas chromatography-quadrupole mass spectrometry system shows that there are many light hydrocarbon organic gases in the ore-forming fluid, which are mainly composed of C 1 -C 4 saturated alkanes and only trace C 2 -C 4 unsaturated olefins and aromatics, Indicating that the metallogenic process is basically unaffected by the high temperature magmatic activity. Chemical equilibrium studies have shown that these light hydrocarbon gases are a mixture of microbial origin and genesis of Type II kerogen in sedimentary rocks
