Great progress has been made in the last twenty years in understanding the unification of the North China Craton. According to a prevailing model it developed by amalgamation of four sub-blocks by three spatially and temporally separate orogenic belts: the first at ~1950Ma formed the Western Block, the second at ~1900Ma created the Eastern Block, and the third at ~1850Ma unified the Eastern and Western...
The 2200–1880Ma igneous rocks in the central and eastern parts of the North China Craton (NCC) constitute a new Hengling magmatic belt (HMB), which includes the ~2147Ma Hengling mafic sill/dyke swarm, the ~2060Ma Yixingzhai mafic dyke swarm, and the ~1973Ma Xiwangshan mafic dyke swarm. The three swarms are contiguous and have experienced variable degrees of metamorphism from greenschist to low amphibolite...
The 1.78 Ga Xiong'er Volcanic Province (XVP) and coeval North China giant mafic Dyke Swarm (NCDS) are the most important magmatic events occurring after the amalgamation of the North China craton (NCC). The XVP consists of 3–7 km of extrusive volcanics and some feeder dykes/sills located along the southern margin of the NCC and extending over an area >0.06 M km 2 . Compositions vary from...
