Article Classification and Generation of the Enclaves in Karapınar-Karacadağ Volcanic Rocks (Central Anatolia)(2021) Korkmaz, Gülin Gençoğlu; Kurt, Hüseyin; Asan, KürşadKarapınar-Karacadağ Volcanic Rocks (KKVR) have very complex magmatic history and outcropped the southwestern part of the Cappadocia Volcanic Province (Central Anatolia). Here we present the petrography and whole-rock chemistry of the enclave-bearing rocks to constrain their source and evolution history. These petrographic observation and geochemical data reveal that the enclaves in the Karapınar-Karacadağ volcanic rocks are magma mixing/mingling enclaves (MME), magma segregation enclaves (MSE), and xenoliths. Here we discriminated these enclaves into eight different types according to their mineral composition and textural features. The magma mixing/mingling enclaves (Type 1, 7, 8) are the mixing products of coeval more felsic and mafic magmas. They show hypocrystalline porphyritic, holocrystalline granular, and intergranular textures, and rich in mafic minerals, and have characteristic petrographic features such as quenched amphibole, bladed biotite, ocelli-quartz, sieved and cellular plagioclases. In andesites they range from basalt to andesite in composition. However, in basalts, they are in basaltic composition. The magma segregation enclaves (Type 2, 4, 5, 6), which are observed in almost all the KKVRs, are cognate xenolith because of plucking from the different parts of the magma chamber. They are holocrystalline and granular in texture. The magma segregation enclaves contained in the andesitic host rocks are hornblende gabbro and pyroxene gabbro in composition, whereas in the basaltic host rocks they are dunite, lherzolite, and basalt in composition. The xenolithic enclaves (Type 3) are observed in the basalts as quartz, plagioclase, biotite, and amphibole xenocrysts. Major oxides and trace element data of the studied rocks indicate that the MSEs are more primitive than their host rocks, and all of the enclaves (MME-MSE) are in accordance with their hosts. According to petrographic observations and geochemical data we propose that fractional crystallization, magma mixing and assimilation processes have a key role in the evolution of the KKVRs and their enclaves.Conference Object A Petrognetic Model for Evidence of Asthenospheric Input Into the Source of Central Anatolia Quaternary Basalts (central Anatolia)(GEOSCIENCE, 2020) Gençoğlu Korkmaz, Gülin; Kurt, HüseyinIn this study, we present for the first time a petrogenetic model of the Quaternary aged nepheline normative Karapınar basalts (Karapınar-Karacadağ Volcanic Complex-KKVC) to explain the asthenospheric material involvement into their source. In recent studies, it has been proved that nepheline normative basalts cannot only be derived from peridotite melts, and they can also be originated from pyroxenite melts. Investigated basalts from KKVC show orogenic pattern in MORB normalized diagram. Although having flat HREE patterns, which is interpreted as originating from garnet-free source in many studies, these basalts may be derived from a garnet bearing source which underwent higher degree partial melting. Their moderate to low Y (< 25 ppm) and low HREE concentrations (Yb < 2 ppm), along with fractionated HREE patterns (Dy/YbN > 1) indicate that garnet was likely to have been involved in the source of the rocks. Furthermore, the most primitive basalts (B1; MgO~10-12 wt%) contain Zn/Fe (*10000) ratio (~16) resembling those of pyroxenite derived melts. Here, we present partial melting and binary mixing models for the Karapınar basalts. The results for modal batch partial melting model of spinel lherzolite and garnet pyroxenite show that mixing between pyroxenitic and peridotitic melts can produce the observed trace element heterogeneities of the most primitive basalts. Although melting model shows that the basalts have plottod into the area between the pyroxenitic and peridotitic sources whose melting degrees are minimum 30% and 5% respectively, the binary mixing model indicates that the rocks were derived from a mixture source of 50% molten pyroxenite and 3% molten peridotite. Furthermore, the mixing model also suggest that the proportion of the pyroxenitic melts in the source should be minimum 45%. According to geochemical data and petrogenetic calculations, we propose a mixing model that nepheline normative basalts were derived from mixing of a peridotitic source with a pyroxenitic source which was brought from the deeper parts of the upper mantle by asthenospheric upwelling.Conference Object Marble Sector in Turkey(ENAR, 2019) Kurt, HüseyinArticle Citation - WoS: 1TEPEKENT (KONYA-ORTA ANADOLU) YÖRESİNDEKİ VOLKANİK KAYALARIN PETROGRAFİSİ, JEOKİMYASI VE PETROLOJİSİ(Konya Teknik Univ, 2022) Eryigit, Busra; Kurt, Hüseyin; Asan, Kürşad; Gençoğlu Korkmaz, Gülin; Korkmaz, Gulin GencogluBu çalışmada, Tepekent yöresi (Konya-Orta Anadolu) yüzeyleyen Miyosen yaşlı riyolitik, dasitik ve bazaltik lav akıntıları ve bunların piroklastiklerinin petrografisi, mineralojisi, jeokimyası ve petrolojisi incelenmiştir. İncelenen kayalar Toplam alkali-silika (TAS) diyagramına göre yüksek potasyum içerikli bazaltik traki-andezit, dasit ve riyolit bileşiminde kayalardır. Bununla birlikte incelenen bazaltik traki-andezitler Na2O-K2O içeriklerine göre şoşonit olarak da adlandırılmaktadır. Dasitik kayalar yer yer mm’den dm’ye değişen boyutta anklav içermektedir. Anklavlar TAS diyagramında traki-bazalt alanına düşmekte olup ana kayalarından daha mafik bir bileşim sergilemektedir. Bazaltik traki-andezitler holokristalin porfirik doku gösterirken, dasitler değişen volkanik cam içerikleri ile hipokristalin porfirik doku sergilemektedir. Bazaltik traki-andezitler olivin, klinopiroksen, plajiyoklaz ve Fe-Ti oksit içermekte, nadiren zeolitleşme ve olivinlerde iddingsitleşmeler göstermektedir. Dasitler amfibol, biyotit, plajiyoklaz, Fe-Ti oksit ve nadiren de kuvars mikro fenokristallerinin içerisine dağıldığı, aynı minerallerin mikrokristallerine ilaveten volkanik camdan oluşan hamur içeriğine sahiptir. Dasitik ana kayalarda yer alan anklavlar ana mafik mineral olarak amfibol içermekte olup, magma mixing anklavlarında sık sık rastlanan ince taneli dokuya sahiptir, bununla birlikte, bıçaksı biyotit, söndürülmüş amfibol ve elek dokulu plajiyoklaz gibi dokusal özellikler sergilemektedir. Riyolitler ise kuvars, plajiyoklaz ve Fe-Ti oksit mikrofenokristalinin yanı sıra önemli derecede sanidin ve biyotit içermektedir.

Volcanic Complex (KCVC) and (2) Karap??nar Volcanic Field (KPVF). The investigated volcanic units are the southwes-tern part of the Neogene to Quaternary Cappadocia Volcanic Province (CVP) in Central Anatolia. The CVP generally displays calc???alkaline affinity in the Late Miocene to Pliocene rocks, but both calc-alkaline and sodic alkaline affinity in the Plio???Quaternary rocks, all of which have an orogenic geochemical signature. Such a volcanic activity contradicts the Western and Eastern Anatolian volcanism characterized by anorogenic OIB-like sodic alkaline volcanic rocks postdating early orogenic calc???alkaline ones. We hypothesize that such temporal and geochemical variations in the investigated rocks result from crustal contamination and present major and trace element chemistry and Sr???Nd???Pb???O isotope geochemistry, coupled with 40Ar/39Ar geochronology data to restrict the genesis and evolution of the rocks. The Neogene Karacada?? volcanic rocks are represented by lava flows, domes and their pyroclastic equivalents constituting a stratovolcano, and dated by new 40Ar/39Ar ages of 5.65 to 5.43 Ma. They are mainly composed of andesitic, rarely basaltic, dacitic and trachytic rocks and have a calc???alkaline character. Constituting a monogenetic volcanic field, the Quaternary Karap??nar volcanic rocks are typically formed by cinder cones, maars and associated lavas, including xenoliths and xenocrysts plucked from the Karacada?? rocks. They comprise basaltic to andesitic rocks with a transitional affinity, from sodic alkaline to calc???alkaline. Both the Karacada?? and Karap??nar volcanic rocks display incompatible trace element patterns rather characteristic for orogenic volcanic rocks. The Sr, Nd and Pb isotopic systematics of both units show a relatively narrow range, but their ??18O values are markedly different. The Karacadag volcanic rocks have ??18O values ranging from 7.5 to 8.9 ???, resembling those of subduction-related basalts, but the Karap??nar volcanics have ??18O ratios between 5.7 and 6.5 ??? corresponding to OIB-like rocks. Additionally, ??18O values and 87Sr/86Sr ratios correlate positively with SiO2 in the rocks, indicating that contamination played an important role during differentiation processes. All the data obtained suggest that the Karacada?? basaltic rocks stemmed from a subduction-modified lithospheric mantle source. On the other hand, the origin of the Karap??nar basaltic rocks can be explained in terms of OIB-like melts contaminated with the Karacada?? volcanic rocks to gain orogenic geochemical signature, which may be an alternative model for the origin of the CVP sodic alkali basalts.Conference Object Conference Object Petrochemical Stratigraphy of Cumulate Enclave Bearing Andesites From Karapınar-Karacadag Volcanic Complex (konya, Central Anatolia)(GEOSCIENCE, 2020) Gençoğlu Korkmaz, Gülin; Kurt, HüseyinAmphibole and pyroxene major and trace element compositions from the cumulate enclave bearing andesites from the Karapınar - Karacadag Volcanic Complex, in Konya (Turkey), have been analyzed by electron microprobe and laser ablation inductively coupled plasma mass spectrometry. A petrochemical stratigraphy can be interpreted for the rocks by using major and trace element contents of the minerals and their changes from center to rim. Amphibole (GK-35C1) of the cumulate enclave, from core to rim, contains Li = 107-103-112 ppm, Ti = 7760-6120-772 ppm, V = 410-342-415 ppm, Cr = 149-166-249 ppm, Zr = 79-94-88 ppm, Mn = 1764-1961-1726 ppm. However host rock’s amphibole grain (GK-35C6), from core to rim, includes Li = 52-111-97 ppm, Ti = 7760-6120-772 ppm, V = 496-520-351 ppm, Cr = 10-69-11 ppm, Zr = 117-53-50 ppm, Mn = 1790-2723-3300 ppm. Moreover, pyroxene from the host rock has 10.7-8.5-11.6 ppm Li, 1230-658-1933 ppm Ti, 162-114- 202 ppm V, 29-7-1420 ppm Cr, 31-16-42 ppm Zr, 4010-3721-2422 ppm Mn. Amphibole thermobarometer calculations have yielded temperature and pressure estimates 993-915°C and 5-2.17 kbar for enclave and host rock, respectively. Also, clinopyroxene geothermobarometer calculations have given 1.34 kbar pressure and 1116°C temperature. Especially the mineral chemistry data of amphiboles and pyroxenes show that the cumulate enclave is more primitive than its host, and enclave were formed at an earlier stage. Geothermobarometer calculations also indicate that the amphiboles in the enclave was formed at a deeper depth than the pyroxenes in the host and the enclave was broken off during convection in the magma chamber and brought to the host. Oscillatory and reverse zonning in terms of Li, Ti, Zr, Hf, Cr, V contents in the minerals indicate magma replenishment. In the host rock, decreasing in Zr and Hf contents from core to rim shows co-magmatic zircons with the amphiboles. Ti negative anomaly in the amphiboles exhibits that they crystallized after Fe-Ti oxide formation. In the light of the mineral chemistry data, Petrochemical stratigraphy (P) should be as in the bottom. P1) Formation of the amphibole cores in the cumulate enclave, after Fe-Ti oxides formations P2) Recharging of the amphiboles in the enclave, P3) Formation of the host rock’s amphibole cores and crystallization of comagmatic zircons P4) Breaking off the cumulate enclaves with convection and settling in the host rock, while the recharging of the host rock amphiboles, P5) Formation of host rock’s pyroxene cores, P6) recharging of the pyroxenes P7) crystallization of the plagioclase and quartz minerals in the shallow depths of the upper crust.Article Classification and Generation of the Enclaves in Karapınar-Karacadağ Volcanic Rocks(TURKGEO, 2021) Gençoğlu Korkmaz, Gülin; Kurt, Hüseyin; Asan, KürşadKarapınar-Karacadağ Volcanic Rocks (KKVR) have very complex magmatic history and outcropped the southwestern part of the Cappadocia Volcanic Province (Central Anatolia).
