“…In recent years, significant advances have been made in understanding their evolutionary histories. We understand that the NCC became a stable continental block through amalgamation of small Archean blocks, while dispute exists on the timing of amalgamation (Wu and Zhong, 1998;Zhao et al, 2001Zhao et al, , 2005Zhao et al, , 2006Kusky et al, 2001Kusky et al, , 2004Wilde et al, 2002;Kusky and Li, 2003;Wilde and Zhao, 2005;Guo et al, 2005;Kröner et al, 2005aKröner et al, ,b, 2006Wan et al, 2006a, b;Polat et al, 2006;Zhang et al, 2006Zhang et al, , 2009Li and Kusky, 2007;Faure et al, 2007;Trap et al, 2007Trap et al, , 2008Trap et al, , 2009aZhai et al, 2007Zhai et al, , 2010Kusky, 2011;Nutman et al, 2011;Zhai and Santosh, 2011 and references therein). The YC had a different evolutionary history from the NCC (e.g.…”
