Objective The North China Craton(NCC)is the largest and oldest one among the worldwide cratons.It preserves important imprints of the Earth’s early history,including crust formation,stabilization and reworking.The Yinshan Block(YB)constitutes the northwestern part of NCC,and contains extensive exposure of Archean rocks(Fig.1).This block has documented intricate Neoarchean tectonothermal events,which can provide constraints on the geodynamic processes responsible for the evolution of Objective The North China Craton (NCC) is the largest and oldest one among the worldwide cratons.
