Effects of melt percolation on iron isotopic variation in peridotites from Yangyuan, North China Craton

The petrology, geochemistry and Fe isotopic composition of two suites of mantle xenoliths (magnesium-lherzolites and Fe-rich lherzolites) and their associated mineral separates from Yangyuan, in the Central Zone of the North China Craton, were measured in detail to investigate the effects of metasomatism on Fe isotope fractionation and mantle Fe isotopic heterogeneity. The magnesium-lherzolites (Mg# = 89.8 to 90.9; TFeO = 8.3 to 8.9 wt.%) from...
