Continental crust is too Si-rich and Mg-poor to derive directly from mantle melting, which generates basaltic rather than felsic magmas. Converting basalt to more felsic compositions requires a second step involving Mg loss, which is thought to be dominated by internal igneous differentiation. However, igneous differentiation alone may not be able to generate granites, the most silicic endmembe...

With proven reserves of 9.836 × 1010 m3, the largest known natural gas reservoir among terrigenous basement rocks has been discovered within granitoids northern Qaidam Basin. Due to their high heterogeneity, genesis reservoirs remains unknown. Herein, structure weathering crust in and potential controlling factors on development mechanism are discussed using a multidisciplinary approach based d...
