通过对汉诺坝玄武岩中二辉橄榄岩等捕虏体的地幔矿物内硫化物包裹体进行电子探针分析 ,查明了硫化物包裹体的主要组成 ,其Ni/Fe比值与原寄生地幔岩有关 .二辉橄榄岩中硫化物包裹体中铁镍硫化物 (均为镍黄铁矿成分 )的Ni/Fe比值明显高于橄榄辉石岩的 (以镍黄铁矿为主 ,部分为磁黄铁矿 ) .CO2 包裹体的激光拉曼探针表明硫 (H2 S +SO2 )在气相中普遍高于 2 0 % (摩尔百分数 ) ,与出现较多硫化物熔体包裹体有关 .
Electron microprobe analysis of mantle sulfide inclusions in xenoliths from Hannuoba basalts, such as lherzolite, revealed the main composition of the sulfide inclusions. The Ni / Fe ratio was similar to that of the proto-parasitic mantle rocks The Ni / Fe ratio of the nickel-iron sulphides (both of which are pentlandite) in the sulfide inclusions in the lherzolites is significantly higher than that of the olivine pyroxene (dominated by pentlandite and partly magnetically yellow Iron ore) .The laser Raman probe of CO2 inclusions shows that sulfur (H2S + SO2) is generally higher than 20% (mol%) in the gas phase, which is related to the occurrence of more sulfide melt inclusions.
