The noble gases, in particular helium isotopes, provide valuable information on the mantle source of recentbasaltic volcanism, especially when linked to trace elements and radiogenic isotopes. Although the alkalinevolcanics in the Kütahya region have been studied in detail by several works by means of trace element variations,radiogenic dating and isotope systematics, noble gas isotope compositions that could signiﬁcantly contribute todynamics of volcanism have not been investigated yet. In this study which aims to ﬁll the deﬁciency of such data,helium isotope compositions of olivine-basalts in Kütahya region are measured.In this study we report helium isotope compositions of olivine from basalts. In olivine-basalts in alkalinevolcanic rocks from the Kütahya region, western Turkey, are investigated. 3He/4He range from 3.0 to 5.19 Ra.These low helium isotope values are most probably indicative of a lithospheric mantle source. Kütahya alkalinevolcanics are enriched in incompatible elements and show prominent negative Ti, Nd and Ta anomaly. Primitivemantle normalized trace element concentration patterns clearly display continental crustal contamination.Chemical compositions and helium isotope systematics imply contribution of a lithospheric mantle source andcontamination of continental crust in the genesis of the Kütahya alkaline lavas.

Investigation of helium isotope variations of alkaline volcanic rocks In Osmaniye Region Turkey Aral, Duru; Mutlu, Halim; Aldanmaz, Ercan; Güleç, Nilgün Türkan; Stuart, Fın (null; 2016-09-05) The noble gases, in particular helium isotopes, provide valuable information on the mantle source of recentbasaltic volcanism, especially when linked to trace elements and radiogenic isotopes. Although the alkalinevolcanics in the Kütahya region have been studied in detail by several works by means of trace element variations,radiogenic dating and isotope systematics, noble gas isotope compositions that could signiﬁcantly contribute todynamics of volcanism have not been investigated yet.

Investigation of gas hydrate potential of the Black Sea and modelling of gas production from a hypothetical Class 1 methane hydrate reservoir in the Black Sea conditions Merey, Sukru; Sınayuç, Çağlar (2016-02-01) Gas hydrate deposits which are found in deep ocean sediments and in permafrost regions are supposed to be a fossil fuel reserve for the future. The Black Sea is also considered rich in terms of gas hydrates. It abundantly contains gas hydrates as methane (CH4 similar to 80-99.9%) source. In this study, by using the literature seismic and other data of the Black Sea such as salinity, porosity of the sediments, common gas type, temperature distribution and pressure gradient, it was estimated that up to 71.8 (...
Investigation of phase selection hierarchy in Mn–Al alloys Genc, Ayse Merve; Acar, Ozgun; Turan, Servet; Kalay, Ilkay; Savacı, Umut; Kalay, Yunus Eren (Elsevier BV, 2019-12-01) Primarily attributed to the formation of the ferromagnetic τ-phase, near equiatomic composition of Mn–Al have recently received much attention in permanent magnet industry. Several mechanisms have been proposed in literature for the τ-phase formation but controversy still arises regarding the dominating mode. In the current work, MnAl-based alloys having different compositions in a range between Mn50.5Al49.5 and Mn57Al43 have been studied by means of in-situ high energy X-ray diffraction, differential scann...
Spatial variations in gas and stable isotope compositions of thermal fluids around Lake Van: Implications for crust-mantle dynamics in eastern Turkey Mutlu, Halim; Güleç, Nilgün Türkan; Hilton, David R.; Aydın, Harun; Halldorsson, Saemundur A. (2012-03-18) We investigate the helium (He-3/He-4) and carbon (delta C-13) isotope compositions and relative abundance ratios (CO2/He-3) of gas samples together with the stable isotope compositions of dissolved carbon and sulfur and the oxygen and hydrogen isotopic compositions of the associated water phase from a number of geothermal fields located around Lake Van in eastern Anatolia, Turkey. The mantle-derived helium component, which is likely transferred to the crust beneath eastern Turkey by recent magmatism, is fou...
Analysis of the Hall effect in TlGaTe2 single crystals QASRAWI, ATEF FAYEZ HASAN; Hasanlı, Nızamı (IOP Publishing, 2009-06-10) The electrical resistivity and Hall coefficient of p-type TlGaTe2 crystals were measured in the temperature range of 110-320 K. The electrical resistivity, charge carrier density and Hall mobility data for the crystals have been analyzed by means of existing theories and models to determine the extrinsic energy levels, the carrier effective mass, the donor and acceptor concentrations and the dominant scattering mechanism in the crystal as well. The analysis of the temperature-dependent electrical resistivit...
