| 英文摘要 | Granulite xenoliths are important samples for understanding the forming and evolution of the crust. The granulite xenoliths enclosed in Cenozoic basalt of Hannuoba, Hebei Province, China, contain four types of sulfide assemblages: isolate rotundity enclosed sulfides, intergranular sulfides between minerals, secondary sulfide inclusions ranging in linear, and fissure-filling sulfides. Electron microprobe analysis shows that the components of sulfides are Ni-poor pyrrhotite with the molar ratios of (Ni+Co+Cu)/Fe less than 0.2. The molar ratios of (Fe+Cu+Co+Ni)/S are less than 0.875 of normal pyrrhotite, and are less than those of mantle xenoliths, reflecting a sulfur-saturated environment. Pyrrhotite in various occurrences contains some Au and Ag, with the averages of 0.19wt%-0.22wt% Au and 0.01 wt%-0.02wt% Ag, showing the gold mineralization related to the granulitization of low crust. Ni, Co and Cu have a normal correlation with S in pyrrhotite, indicating that heavy metal elements have a same source similar to sulfur because of the degasification of upper mantle. |
