用激光拉曼探针分析了冲绳海槽南部橄榄拉斑玄武岩中的流体包裹体成分。结果表明 ,流体包裹体的主要成分为 CO2 ,此外 ,还有 H2 O、H2 S、CH4 、N2 、C2 H2 、C2 H4 、C3 H8组分。不同宿主矿物 ,其包裹体成分中 CO2 、H2 O和 CH4 的相对含量也不同 ,其中 ,钙长石中包裹体的 CO2 含量最高 ,贵橄榄石中的次之 ,普通辉石中的最少。CH4 和 H2 O的含量趋势与 CO2 相反。根据这 3种宿主矿物中流体成分及其含量变化特点 ,推断这 3种宿主矿物的结晶顺序为钙长石、贵橄榄石、普通辉石 ,并认为流体包裹体中的烃类和水可能主要来自熔体上升过程中所接触的沉积地层 The laser Raman probe was used to analyze the fluid inclusions in the southern Raman basalt in the Okinawa Trough. The results show that the main components of fluid inclusions are CO2, in addition, there are H2 O, H2 S, CH4, N2, C2 H2, C2 H4, C3 H8 components. In different host minerals, the relative contents of CO2, H2 O and CH4 in the inclusions are also different. Among them, the content of CO2 in the inclusions is the highest, the least in the olivine and the less in the pyroxene. The trend of CH4 and H2 O content is opposite to that of CO2. According to the characteristics of the fluid composition and the content of these three host minerals, it is concluded that the crystal order of the three host minerals is anorthite, peridotite, and pyroxene, and the hydrocarbons and water in the fluid inclusions may be mainly From the sedimentary formation contacted by the melt as it rises
