“…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. Zhai et al (2000Zhai et al ( , 2005Zhai et al ( , 2010 proposed that the NCC can be divided into several microblocks connected by greenstone belts and granites and were amalgamated at the end of the Neoarchean (∼2.5 Ga).…”
