The Late Neoproterozoic-Early Palaeozoic suture zones within the Central Orogenic Belt of China can be considered a system—the Kunlun-Qilian-Qinling suture system(KQQ suture system).It is basically divided into the western,central and eastern *** western sector consists of the Kda-Subashi suture zone,the Mazar-Kangxiwar suture and the central West Kunlun *** central sector covers the following five suture zones: the Altun,North Qilian,Qaidam northern marginal,Qimantag-Wutuo and East Kunlun southern marginal sutures,in addition to some microblocks such as the mid-south Qilian,Qaidam,Ayakkum and Maqen *** eastern sector is composed of the Shangdan suture zone,Mianle suture zone and central Qinling-Dabie *** KQQ suture system experienced(1) extending-rifting of the Rodinia super-continent in the early-middle Sinian(~780-600 Ma);(2) the formation and evolution of the KQQ archipelagic ocean during the Late Sinian-Ordovician(~600-440 Ma),and(3) closing of the KQQ ocean and forming of the KQQ suture system during the Late Ordovician-early Silurian(~440-400 Ma).As a system comprising many suture zones and microblocks,the KQQ suture system constitutes the foundation of the Central Orogenic Belt of China.
