摘　　要：Objective The Khondalite Belt is a nearly E–W-trending Paleoproterozoic Himalayan-type orogen in the Western Block of the North China Craton. It is regarded as a result of the collision between the northern Yinshan Block and the southern Ordos Block at ~1.95 Ga, which led to the formation of the united basement of the Western Block(e.g., Zhao et al., 2005;Yin et al., 2011). The Khondalite Belt has undergone long-term continent-continen collisional orogenic processes, and a remarkable series of late-stage orogen-parallel ductile shear zones developed(e.g., Huang et al., 2013;Gong et al., 2014).
