“…Microcontinents and continental fragments are considered to have been incorporated into the CAOB during its accretion (Windley et al, 2007;Gao et al, 2011;Kröner et al, 2012;Alexeiev et al, 2015;Zhang et al, 2015aZhang et al, ,b,c, 2016. However, their origins are still controversial, with some researchers assuming that some microcontinents within the CAOB had a Gondwana derivation and were then accreted onto the southern margin of the Siberian Craton (Zonenshain et al, 1990;Buslov et al, 2001;Dobretsov et al, 2003;Kheraskova et al, 2003;Laurent-Charvet et al, 2003;Xiao et al, 2010). In contrast, models that favor the origin of the Siberian Craton have been proposed recently (Berzin and Dobretsov, 1994;Sengör and Natal'in, 1996;Kuzmichev et al, 2001;Turkina et al, 2007;Zhou et al, 2009Zhou et al, , 2010aZhou et al, ,b,c, 2011.…”
