“…Geoffroy, 2005;Abdelmalak, 2010;Abdelmalak et al, 2012). Magmatic activity is typically expressed within the stretched continental crust by: (1) large wedges of seaward-dipping basaltic flows and tuffs extruded at the surface (Hinz, 1981;Eldholm, 1991;Planke et al, 2000;Menzie et al, 2002); (2) massive sill/dyke intrusions within the sedimentary basin (Svensen et al, 2004;Planke et al, 2005); (3) melt emplacements into the upper and mid continental crust by mafic to ultramafic intrusions (Karson and Brooks, 1999;Klausen and Larsen, 2002;Lenoir et al, 2003;Geoffroy et al, 2007;Meyer et al, 2009b); and (4) a highvelocity lower crustal body (LCB) at the base of the crust characterized by high Vp velocity (Vp> 7.0 km/s) (White et al, 1987;Kelemen and Holbrook, 1995;Holbrook et al, 2001;Mjelde et al, 2009a;Mjelde et al, 2009b).…”
