Subduction-related metasomatic mantle source in the eastern Central Asian Orogenic Belt: Evidence from amphibolites in the Xilingol Complex, Inner Mongolia, China
Mafic rocks in northern accretionary zone of CAOB record 340–309 Ma extension. The rocks derived from a depleted mantle source but enriched by oceanic slab. Mantle-derived magma and oceanic crust recycling affected the primitive magma.
