英文摘要	Mineral compositions, clinopyroxene trace-element and Sr-Nd-Hf isotopic compositions, whole-rock major element and platinum group element (PGE) contents, and Re-Os isotopes are reported for peridotite xenoliths in the Cenozoic alkali basalts from Yangyuan, Hebei Province (China), in order to constrain the nature of the subcontinental lithospheric mantle beneath the central part of the North China Craton, and further to investigate the mechanism of decratonization. The xenoliths mainly consist of spinel lherzolites and minor spinel pyroxenites and spinel harzburgites with equilibration temperatures of 890-1060 degrees C. The olivine in these xenoliths have Mg number (%Fo) ranging from 88.2 to 91.6. According to the chemical characteristics, two groups of peridotites can be identified, i.e., group 1 are spinel lherzolites and spinel harzburgite that are depleted in Pt, Pd and Re (i.e., P-PGEs) relative to Os, Ir and Ru (i.e., I-PGEs) and their clinopyroxenes are depleted in light rare earth elements (LREEs), whereas, Group II are spinel lherzolites that are enriched in P-PGEs relative to I-PGEs and their clinopyroxenes are enriched in LREEs relative to HREEs. The spinel lherzolites have radiogenic Os-187/Os-188 ratios ranging from 0.1182 to 0.1262, whereas, the spinel harzburgites have relatively low Os-187/Os-188 ratios with Proterozoic model ages. Clinopyroxenes in the peridotite xenoliths have variable but relatively unradiogenic Sr (Sr-87/Sr-86 = 0.7026-0.7046) and radiogenic Nd (epsilon(Nd) = + 2.0 to + 14.7) and Hf (epsilon(Hf) = + 8.8 to + 37.9) isotopic compositions. All these geochemical features indicate that the subcontinental lithospheric mantle beneath Yangyuan had experienced variable degrees of melt extraction and mantle metasomatism by the silicate melts represented by spinel pyroxenites. The spinel pyroxenites are enriched in LREEs and P-PGEs relative to HREEs and I-PGEs. Clinopyroxenes in pyroxenite xenoliths have high Sr-87/(86) Sr ratios of 0.7054-0.7063, negative epsilon(Nd) (-3.4 to -15.8) and eHf (- 2.0 to -22.0) values, and high Os-187/Os-188 ratios of 0.2196-0.3343, indicating that the silicate melts were derived from ancient lower continental crustal materials. Our data suggest that the lithospheric mantle beneath Yangyuan had been metasomatized by silicate melts derived from recycled ancient lower crust, indicating that decratonization of the North China Craton was possibly induced by delamination of the lower crust and lithospheric mantle.
