“…Several models have been proposed for the ori gin of MMEs in granitic rocks: (1) a hybrid or magma mixing and/or mingling model arguing that MMEs represent extraneous mafic magma blobs likely produced from the mantle that have mingled or partly mixed with felsic magmas derived from the crust or felsic magmas derived by fractional crystallization (e.g., Didier, 1973;Reid et al, 1983;Vernon, 1983Vernon, , 1984Vernon, , 1990Vernon, , 2014Cantagrel et al, 1984;Eberz and Nicholls, 1988;Vernon et al, 1988; Barbarin, 1990;Castro et al, 1990aCastro et al, , 1990bDorais et al, 1990;Fourcade and Javoy, 1991;Holden et al, 1991;Orsini et al, 1991;Poli and Tommasini, 1991;Elburg and Nicholls, 1995;Stimac et al, 1995;Elburg, 1996aElburg, , 1996bMaas et al, 1997;Collins et al, 2000;Ratajeski et al, 2001;Perugini et al, 2003;Tepper and Kuehner, 2004;Ilbeyli and Pearce, 2005;Kocak, 2006;Chen et al, 2009a;Qin et al, 2010;Sun et al, 2010;Perugini and Poli, 2012;Xiong et al, 2012;Zi et al, 2012;Clemens and Elburg, 2013;Dan et al, 2015); (2) a restitic origin model interpreted the enclaves as refractory pods of the source rock of the granitoid (e.g., White and Chappell, 1977;…”
