This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy. The article duplicates significant parts of a paper that had already appeared in, and was withdrawn from Precambrain Research (http://dx.doi.org/10.1016/j.precamres.2014.08.012). The paper was also submitted without the knowledge of all the co-authors, and included another,...
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 Badu complex and associated Paleoproterozoic granitoids are among the oldest known rocks in the Cathaysia Block in South China. The Paleoproterozoic units of the Badu complex are dominantly composed of metapelitic rocks and meta-greywackes. Here we report LA-SS-ICP-MS (laser ablation-split-stream inductively coupled plasma-mass spectrometry) zircon U–Pb data from a newly discovered garnet-bearing...
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...
Zircon U–Pb and hornblende 40 Ar/ 39 Ar dating document an Early Permian emplacement time for the Hercynian Guyang batholith from the northern margin of the North China Craton (NCC), with a variety of lithologies including: gabbro–gabbroic diorite–leuconorite, diorite and granodiorite, microgranular magmatic enclaves (MME), mafic dyke and monzogranite. Field relations, petrological,...
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...
Our recent studies show that the lower crust and lithospheric mantle in the eastern North China Craton (NCC) was thinned in the Mesozoic. The lower crust played a key role in the tectonic mechanism that led to lithospheric thinning. Geochemical data from volcanic rocks and xenoliths support the idea that delamination of the lower crust and lithospheric mantle took place only along the northern and...
Petrological analysis, zircon trace element analysis and SHRIMP zircon U–Pb dating of retrogressed eclogite and garnet granulite from Bibong, Hongseong area, SW Gyeonggi Massif, South Korea provide compelling evidence for Triassic (231.4±3.3 Ma) high-pressure (HP) eclogite facies (M1) metamorphisms at a peak pressure–temperature (P–T) of ca. 16.5–20.0kb and 775–850°C. This was followed by isothermal...
