Precambrian key tectonic events and evolution of the North China craton

Abstract: The North China craton (NCC) is one of oldest cratons in the world, with crust up to c. 3.8 Ga old, and has a complicated evolution. The main Early Precambrian geological events and key tectonic issues are as follows. (1) Old continental nuclei have been recognized in the NCC, and the oldest remnants of granitic gneiss and supracrustal rocks are 3.8 Ga old. The main crustal growth in the NCC took place at 2.9–2.7 Ga. The NCC can be divided into several microblocks, which are separated by Archaean greenstone be… Show more

“…11b and c), suggesting two episodes of crustal growth from the Late Mesoarchean to the beginning of the Early Paleoproterozoic in the southern segment of the TNCO, which are contemporaneous with the two main crustal growth episodes recognized in the NCC (2.9-2.7 Ga and 2.55-2.50 Ga; Zhai et al, 2010). Juvenile continental crust is produced at subduction zones or by mantle plumes (Condie, 1998).…”

“…1a) is the oldest cratonic block in China (∼3.8 Ga; Liu et al, 1992), with widespread Archean to Paleoproterozoic rocks (Fig. 1a) forming during several tectonic cycles (e.g., Zhao et al, 2005Zhao et al, , 2012Lu et al, 2008;Zhai et al, 2010;Zhao and Zhai, 2013). It is commonly recognized that the NCC resulted from amalgamation of several microblocks, but the timing and processes involved are still a subject of debate (e.g., Kusky and Li, 2003;Zhai et al, 2000Zhai et al, , 2005Zhai et al, , 2010Zhao, 2001;Zhao et al, 2005Zhao et al, , 2012Zhao and Zhai, 2013), with several competing models proposed.…”

“…It is well known that Archean rocks are extensively exposed in the North China craton. The oldest rocks and crustal materials were dated at 3.8 Ga. Two major phases of magmatism occurred in 2.8-2.7 Ga and 2.55-2.50 Ga, whereas high grade metamorphism took place at ~2.5 Ga [2,3]. In contrast, the Precambrian basement of the Yangtze craton is poorly exposed; it was deeply buried and was covered by voluminous Neoproterozoic-Phanerozoic sedimentary sequences.…”
