Geochemical and Sr-Nd Isotopic Characteristics of Post-Collisional Calc-Alkaline Volcanics in the Eastern Pontides (NE Turkey)
earth siences rocks gneisses
2011/3/22
Major, trace element, K-Ar age and Sr-Nd isotopic data are presented for the Eocene Torul volcanics in the eastern Pontide orogenic belt (NE Turkey). The studied rocks are composed of basaltic andesit...
Mineral-Chemical Constraints on the Miocene Calc-alkaline and Shoshonitic Volcanic Rocks of Western Turkey: Disequilibrium Phenocryst Assemblages as Indicators of Magma Storage and Mixing Conditions
western Anatolia magma evolution magma mixing compositional zoning disequilibrium parameters crustal magma chambers
2009/7/7
Early to Middle Miocene (22 to 15 Ma) volcanic activity across western Turkey produced a series of lavas and pyroclastic deposits with calc-alkaline and shoshonitic affinities. The erupted magmas show...

In a recent paper, Aslan (2005) presents so far unique petrographic and geochemical data on Sarıhan granodiorite from Eastern Pontides, NE Turkey. Several microtextural characteristics in conjunc...
Stratigraphy and Geochemical Features of the Early Miocene Bimodal (Ultrapotassic and Calc-alkaline) Volcanic Activity Within the NE-trending Selendi Basin, Western Anatolia, Turkey
Western Anatolia lamproite ultrapotassic volcanism bimodal volcanism continental extension
2009/7/7
Western Anatolia has experienced thickening and orogenic collapse subsequent to the Eocene continent-arc collision. The early stage of the post-collisional volcanism in the region was thought to have...
Geochemistry of the Middle Miocene Collision-Related Yamadaği ( Eastern Anatolia) Calc-Alkaline Volcanics,Turkey
calc alkaline volcanics collision Eastern Anatolia Turkey
2010/1/11
Major, trace element and K-Ar age determinations are reported for a suite from the Yamadağı volcanics in the Eastern Anatolia. The exposed rocks mainly consist of medium-potassium calc-alkal...
Contemporaneous Late Cretaceous Calc-alkaline and Alkaline Magmatism in Central Anatolia,Turkey:O Isotope Constraints on Petrogenesis
I-type granite A-type granite oxygen isotope Kaman-Kı rş ehir region central Anatolia Turkey
2010/1/11
A wide variety of rock types were produced by the latest Cretaceous magmatism in the Central Anatolian Crystalline Complex. These rocks can be divided into three distinct units: (i) calc-alkaline, (ii...
Occurrence of Clinoptilolite and Mordenite in Tertiary Calc-Alkaline Pyroclastites from Sardinia (Italy)
Clinoptilolite Fluid/Rock Interaction Mordenite Opal-CT Tertiary Pyroclastic Flows
2011/12/7
Abstract: Clinoptilolite and mordenite occur as diagenetic products of medium-grained, moderately welded and poorly sorted pyroclastic flows belonging to the Tertiary calc-alkaline volcanism of Sardin...
Epidote in calc-alkaline magmas: An experimental study of stability, phase relationships, and the role of epidote in magmatic evolution
Epidote calc-alkaline magmas stability phase relationships the role of epidote magmatic evolution
2012/4/5
Experiments on tonalite and granodiorite wereperformed at conditions ranging from 2.1 to 18kbar and 550 to 850°C to establish the magmatic stability field ofepidote as a function ofP, T,and f02. Atwat...
