In minerals of mantle xenoliths captured within Tertiary alkali-basalt from Xinchang, Zhejiang province, China, many sulfidemelt inclusions were found by the observation of polished thin section. Electron microprobe analysis has been applied to detect the components of sulfide-melt inclusions. The result shows that the sulfide phases of inclusions are mainly pentlandite, and secondarily pyrrhotite, The molar ratio of Ni to Fe, rNi/rFe, of mineral phases in sulfide inclusions is related to olivine contents in host mantle xenoliths. The rNi/rFe, of sulfides from Xinchang samples has a possitive correlation to r(Fe+Ni)/rS. The r(Fe+Ni)/rS, becomes higher with the increasing of rNi/rFe In single sulfide-melt inclusions, rNi/rFe, r(Fe+Ni)/rS and Ni contents increase from the center to edge, reflecting a result of different cooling speed in an inclusion. A comparison between the data from Hannuoba, West Eifel of Germany and Nograd-Gomor of east Europe suggests that the composition of the inclusions is different for each area, which indicated that a regional differentiation of sulfide in mantle fluids.
