“…The whole-rock Rb-Sr isochron (Figure 8) ages for the GIC (Karacaören and Kadıncık samples) represent the time of emplacement of (Middle Eocene) plutons in the Tavşanlı Zone. Rb-Sr age determinations are broadly similar to the published ages dated in other studies (Gautier, 1984, Demirbilek, 2012Shin et al, 2013;Demirbilek et al, 2018).…”

“…The medium-and high-K calc-alkaline to shoshonitic and I-type granodiorite and granite can also be formed from partial melting of crustal melts (e.g., . The high ratios of CaO/Na 2 O and CaO/ (MgO+FeO t ) but low ratios of Al 2 O 3 /TiO 2 , Al 2 O 3 / (MgO+FeO t ), Rb/Ba, and Rb/Sr (Figures 15a and 15b) indicate that the granodiorites and granites were derived from different sources (Demirbilek, 2012;Demirbilek and Mutlu, 2012;Demirbilek et al, 2018; this study).…”

“…It may also be noted that K-feldspar derived from potassic solutions formed as the result of nucleation/ growth processes (e.g., Johnson and Glazner, 2010). Mafic and felsic minerals such as biotite, plagioclase, epidote, and titanite formed previously within the growth zone aligned (Figure 7a; Demirbilek et al, 2018). According to Hibbard (1991), this kind of texture points to magma mixing.…”

“…On the basis of their textures and modal mineralogy, four subunits were recognized in the GIC (Kibici, 1994): gray, medium-grained Kadıncık granite ( Figure 5a); gray, porphyritic with euhedral, zoned K-feldspar Dinek granite porphyry ( Figure 5b); gray, medium-grained Tekören granite; and gray, fine-to medium-grained Karacaören granite (Kibici et al, 2008;İlbeyli and Kibici, 2009;Demirbilek, 2012;Demirbilek et al, 2018).…”

“…mainly serpentinized harzburgite and dunite, and lesser pyroxenites, chromitites, and diabase dykes and rare gabbros (Lisenbee, 1972;Önen, 2003). The blueschists, an accretionary complex, and peridotite slabs in the zone are intruded by Eocene-aged plutonic rocks (e.g., Harris et al, 1994;Okay and Satır, 2006;Demirbilek, 2012;Demirbilek et al, 2018).…”

Introduction The Anatolian plate is made up of various continental fragments and suture zones among them. These continental fragments are, from N to S, the Strandja Massif, the İstanbul and Sakarya Zones, the Anatolide-Tauride Block (Anatolide-Tauride Platform), the Central Anatolian Crystalline Complex (Kırşehir Massif, Kırşehir Block, Central Anatolian Massif), and the Arabian Platform (Şengör and Yılmaz, 1981; Şengör et al., 1982; Okay and Tüysüz, 1999) (Figure 1). The northwestern-western part of the Anatolide-Tauride Block consists of the Tavşanlı Zone, the Afyon Zone, and the Menderes Massif (Figure 1). The Tavşanlı Zone is a ~250 km long and ~50 km wide east-west trending belt located just south of the İzmir-Ankara-Erzincan Suture Zone (Figures 1 and 2) (Okay, 2008). This suture zone represents the northern Neo-Tethyan ocean, which began to open between Laurasia and Gondwana from the Middle-Late Triassic (Tekin et al., 2002) and started to close between the Sakarya Zone and the Anatolide-Tauride Block during the Late Cretaceous (in the west) (e.g., Tüysüz et al., 1995; Meijers et al., 2010; Lefebvre et al., 2013). Following the collision, convergence between the Sakarya Zone and the Anatolide-Tauride Block remained until the Late Tertiary (Şengör and Yılmaz, 1981). The zone is made up of blueschists tectonically overlain by an accretionary or mélange complex, peridotite slabs (Figure 2), and granodiorites (Okay et al., 1998). The blueschist sequence contains Permo-Triassic metapelitic schists at the base, overlain by Mesozoic marbles and a series of metabasite, metachert, and phyllite at the top (Okay, 1984). Metamorphic ages for the blueschists yield values between 80.
