Geochemical characteristics of the adakite-like Dodurga Pluton (Central Pontides, N Turkey): implications for Middle Triassic continental arc magmatism in southern Black Sea region

Generation of collision-induced Early to Middle Miocene adakitic magmas in Pertek (Tunceli) area from Eastern Anatolia postsubductional setting, Turkey

“…Different models have been suggested, yet the origin and evolution of adakites or adakitic rocks are still under discussion. For example, high or low pressure fractional crystallization of (hydrated) basaltic magma and crustal contamination (Macpherson et al, 2006;Castillo, 2006); partial melting of metasomatized mantle (Guo et al, 2009;Kadıoğlu and Dilek, 2010;Şen and Şen, 2013;Çoban et al, 2020); mixing of lower crust and slab-derived melts (Çimen, 2020); FC and/or differantiation of arc-related magmas along mantle-crust boundary (Eyüboğlu et al, 2011a); partial melting of subducted young and hot oceanic crust (Defand and Drummond, 1990;Kay et al, 1993;Yılmaz-Şahin et al, 2012;Li et al, 2016); partial melting of pristine or juvenile mafic lower crust (Rollinson and Tarney, 2005;Wang et al, 2005;Castillo, 2006;Liu et al, 2008;Xu et al, 2008;Karslı et al, 2019;2020); partial melting of thickened or delaminated continental crust (Zhang et al, 2001;Chung et al, 2003;Wang, et al, 2005;Karslı et al, 2010); slab window-related magmas along a subduction zone (Eyüboğlu et al, 2011a(Eyüboğlu et al, , 2011b2012), or according to isotopic signatures, those of typical subducting slab-derived adakites (O-type) with high positive ƐNd(t) and from post-collisional K-rich adakites (continental, C-type) with negative ƐNd(t) (Azizi et al, 2019) are some of the suggested models envisaged for the origin and evolution of syn-or post-collisional adakitic porphyries.…”
