“…In the absence of geochemical data for local lower crustal rocks, we have collected literature data on lower crustal xenoliths associated with Cenozoic within-plate magmas from the Arabian plates (Nasir, 1992(Nasir, , 1995McGuire and Stern, 1993;Nasir and Safarjalani, 2000;Al-Mishwat and Nasir, 2004;Al-Safarjalani et al, 2009;Forster et al, 2010;Stern and Johnson, 2010;Krienitz and Haase, 2011) to infer the possible consequences of interaction of mantle melts with Arabian-type lower crust. From a major element point of view, the Arabia lower crust xenoliths share many similarities with the whole-rock composition of the Karacadag lavas and those of the neighbouring volcanic districts (Fig.…”
