“…Volcanic products in the İskenderun Gulf area have widely been recognized as originating from an OIB-like asthenosphere (Alıcı et al, 2001;Parlak et al, 2000Parlak et al, , 1998Parlak et al, , 1997Polat et al, 1997;Yurtmen et al, 2000), in which magma ascent may have been facilitated by transtensional tectonics associated with the strike-slip fault systems bounding the African-Anatolian-Arabian plates since the late Pliocene (Bağcı et al, 2011;Italiano et al, 2017;Lustrino & Sharkov, 2006;Parlak et al, 2000;Polat et al, 1997). Additionally, several authors have noted that volcanics in this area, as well as in central Anatolia, exhibit geochemical signatures associated with subduction-related metasomatic processes (Bağcı et al, 2011;Italiano et al, 2017;Polat et al, 1997;Reid et al, 2017;Yurtmen et al, 2000).…”

“…In central southern Anatolia, mantle sources of young volcanics on the shores of the İskenderun Gulf are also thought to resemble an OIB-like asthenosphere (Alıcı et al, 2001;Parlak et al, 2000Parlak et al, , 1998Parlak et al, , 1997Polat et al, 1997;Yurtmen et al, 2000), variously enriched by subduction-related metasomatism (Bağcı et al, 2011;Italiano et al, 2017;Polat et al, 1997;Yurtmen et al, 2000). Upwelling and decompressional melting has in this region been inferred to relate to transtensional tectonics associated with the East Anatolian Fault and oblique eastern Cyprus trench (Bağcı et al, 2011;Italiano et al, 2017;Parlak et al, 2000;Polat et al, 1997) and, further south, to the Dead Sea Fault Zone which runs into Syria (Ma et al, 2011).…”

“…In summary, Late Neogene alkaline volcanism is interpreted to result from very different local tectonic and geodynamic processes throughout Anatolia. Previous studies of Anatolian intraplate volcanics have predominantly used bulk-rock geochemical and isotope data (e.g., Aldanmaz et al, 2006;Alıcı et al, 2001Alıcı et al, , 2002Arger et al, 2000;Bağcı et al, 2011;Chakrabarti et al, 2012;Ekici et al, 2012Ekici et al, , 2014Italiano et al, 2017;Klaver et al, 2016;Lustrino et al, 2012;Polat et al, 1997;Sölpüker, 2007;Yurtmen et al, 2000) to investigate the generation of alkaline magmas across various tectonic settings. However, in view of the complex history of the region following late-stage subduction or collision of the African, Eurasian, and Arabian plates, the nature and interaction of mantle and subduction components are difficult to decipher using bulk-rock geochemistry alone.…”

Mantle Sources of Recent Anatolian Intraplate Magmatism: A Regional Plume or Local Tectonic Origin?

et al. 2018

We present an extensive study of rehomogenized olivine‐hosted melt inclusions, olivine phenocrysts, and chromian spinel inclusions to explore the link between geodynamic conditions and the origin and composition of Pliocene–Quaternary intraplate magmatism in Anatolia at Kula, Ceyhan‐Osmaniye, and Karacadağ. Exceptional compositional variability of these products reveals early and incomplete mixing of distinct parental melts in each volcanic center, reflecting asthenospheric and lithospheric mantle sources. The studied primitive magmas consist of (1) two variably enriched ocean island basalt (OIB)‐type melts in Kula; (2) both OIB‐type and plume mid‐ocean ridge basalt (P‐MORB)‐like melts beneath Toprakkale and Üçtepeler (Ceyhan‐Osmaniye); and (3) two variably enriched OIB‐type melts beneath Karacadağ. Estimated conditions of primary melt generation are 23–9 kbar, 75–30 km, and 1415–1215 °C for Kula; 28–19 kbar, 90–65 km, and 1430–1350 °C for Toprakkale; 23–18 kbar, 75–60 km, and 1400–1355 °C for Üçtepeler; and 35–27 kbar, 115–90 km, and 1530–1455 °C for Karacadağ, the deepest levels of which correspond to the depth of the lithosphere‐asthenosphere boundary in all regions. Although magma ascent was likely facilitated by local deformation structures, recent Anatolian intraplate magmatism seems to be triggered by large‐scale mantle flow that also affects the wider Arabian and North African regions. We infer that these volcanics form part of a much wider Arabian‐North African intraplate volcanic province, which was able to invade the Anatolian upper plate through slab gaps.

“…In the case of Pamukkale, FIs show a significant addition of mantle‐derived 3 He and atmosphere‐derived He ( 3 He/ 4 He down to 0.5 Ra, corresponding to a minimum of ~6% of mantle contribution, Figure . For this calculation we assumed 8 Ra for the local mantle; Aral et al, ; Italiano et al, ). We argue that these travertines formed in a system of lithospheric‐type fractures that able to enhance the circulation of mantle fluids.…”

The understanding of the relationship between the geochemistry of fluids circulating during travertine deposition and the presence of active faults is crucial for evaluating the seismogenetic potential of an area. Here we investigate travertines from Pamukkale and Reşadiye (Turkey), sited in seismic regions and next to thermal springs. These travertines formed ~24,500–50,000 (Pamukkale) and ~240–14,600 years (Reşadiye) BP. We characterize fluid inclusions (FIs) and studied concentration of H2O, CO2, O2 + N2, and 3He, 4He, 20Ne, and 40Ar, and bulk composition (trace elements and δ13C‐δ18O). FIs from both localities are mainly primary with low salinity and homogenization temperature around 136–140 °C. H2O is the major component followed by CO2, with the highest gas content measured in Pamukkale travertines. Concentrations of Ne‐Ar together with O2 + N2 indicate that travertines from both areas precipitated from atmosphere‐derived fluids. The 3He/4He is 0.5–1.3 Ra in Pamukkale and 0.9–4.4 Ra in Reşadiye. Samples with R/Ra > 1 are modified by cosmogenic 3He addition during exposure to cosmic rays. Excluding these data, FIs of Reşadiye are mostly atmosphere‐derived. This implies a shallow formation where the circulation was dominated by meteoric waters, which is consistent with their young age. Instead, FIs of Pamukkale show mixing of mantle‐, crustal‐, and atmosphere‐derived He, indicating that these travertines formed in lithospheric fractures. Based on the δ13CCO2 and δ18O of bulk rocks, we infer that travertines formed involving crustal‐ (mechanochemical rather than organic) and mantle‐derived CO2. Trace elements of Pamukkale and Reşadiye show comparable rare earth element patterns. We conclude that travertines formed in response of seismogenetic activity.
