In this paper, they mainly concluded that these granitoids were emplaced at shallow crustal levels (± km) and were not deformed in a ductile manner as the brittle-ductile boundary of an extended continental crust is much deeper (15-20 km). They also suggested that the Sr-Nd-Pb-O isotopic compositions of the Alaçam granite are consistent with derivation from an older middle crustal source rather than a mantle source. | Comment on “Al-in-hornblende thermobarometry and Sr-Nd-O-Pb isotopic compositions of the Early Miocene Alaçam Granite in NW Anatolia (Turkey)”
