中央造山带范围内的诸多新元古代晚期-早古生代蛇绿岩带可视为一个系统——昆祁秦缝合系。大致可分西、中、东3段。西段包括库地-苏巴什和麻扎-康西瓦2条缝合带及西昆中微地块;中段包括阿尔金、北祁连、柴达木北缘、祁漫塔格-乌妥及东昆仑南缘5条缝合带和中-南祁连、柴达木、阿牙克库木及玛沁4个较大的微地块及诸多较小的微地块;东段为商丹缝合带和勉略缝合带及其所夹持的秦中-大别微地块。昆祁秦缝合系是Rodinia超大陆经历了早-中震旦世（约780～600Ma）初期裂解阶段,晚震旦世-奥陶纪（约600～440Ma）昆祁秦多岛洋阶段,晚奥陶世-早志留纪（约440～400Ma）昆祁秦多岛洋闭合阶段形成的一个包含若干条缝合带和若干个微地块的体系,是中央造山带的基础。 Many of the Neoproterozoic-Early Paleozoic ophiolite belts in the central orogenic belt can be considered as a system - Kunqinqin suture system. Can be roughly divided into West, Middle and East 3 sections. The western segment includes two suture zones of the Kudi-Subbasi and Mazar-Kangxiwa and the Sikkun-Nankai block; the middle section includes the Altyn Tagh, the North Qilian, the northern Qaidam, the Qimattag-Utopia And the southern margin of the East Kunlun 5 suture zone and the central - South Qilian, Qaidam, Ajax Kumu and Maqin 4 larger micro-blocks and many smaller micro-blocks; the eastern section of commercial Dan Suture zone and Mianlue suture zone and its holding Qinzhong - Dabie micro-mass. The Kunqinqin suture system is that the Rodinia supercontinent experienced the early-middle Sinian (about 780 ~ 600Ma) initial cracking stage, the late Sinian-Ordovician (about 600 ~ 440Ma) Qunqin multi-oceanic stage, late Ordovician - Early Silurian (about 440 ~ 400Ma) Kun Qijin multi-oceanic closure phase of the formation of a number of suture and a number of micro-block system is the foundation of the central orogenic belt.
