| 英文摘要 | Mantle xenoliths captured in alkali-basalt occurs widely in the Liuhe district, Jiangsu province, China, dominantly by spinel Iherzolite. Sulfides are commonly found in minerals of the mantle xenoliths. They occur as: (1) early sulfide grains captured by host minerals; (2) intergranular or filling in the fissures; and (3) sulfide-melt inclusions, including one phase sulfide inclusions, sulfide-glass two phase melt inclusions, and CO2-sulfide-glass (sometimes containing silicate daughter minerals) poly-phase melt inclusions. Electron microprobe analysis shows that sulfide-melt inclusions have higher Fe and S contents and lower Ni content than sulfides in fissures do. The molar ratios of Ni to Fe, r(Ni)/r(Fe), of sulfide-melt inclusions range from 0.14 to 1.73, generally from 0.70 to 1.55, while those of intergranular sulfides range from 1.76 to 7.03. Like that of Liuhe, sulfide-melt inclusions in Hannuoba (Hebei province), Xinchang (Zhejiang province) and Qilin (Guangdong province) have higher Fe and S contents and lower Ni content when compared to intergranular sulfides. For both sulfide-melt inclusions and intergranular sulfides, S contents increase from Liuhet Xinchang, and Hannuoba to Qilin, Fe contents increase from Liuhe, Xinchang, Qilin, to Hannuoba; while Ni (+Co) contents decrease from Liuhe, Xinchang, Qilin, to Hannuoba. It is indicated that there is a close relationship between intergranular sulfides and sulfide-melt inclusions. |
