(TUBİTAK Scientific & Technical Research Council Turkey, 2023)The preliminary results of geochemical analyses of the surface sediments from 4 lakes on Robert Island, South Shetland, Antarctica, are presented herein. The samples were collected during the Turkish Antarctic Expedition ... -
The petrogenesis of analcime in the coppermine formation on Robert Island, South Shetland ıslands, Antarctica
(TUBİTAK Scientific & Technical Research Council Turkey, 2023)The South Shetland Islands were shaped by island arc volcanism that occurred from the Jurassic to the Quaternary. Robert Island is located in the center of this archipelago, and Coppermine Peninsula, located on the ... -
Geochemistry of the massive dolomites in Eastern Black Sea region: REE implications for dolomite petrogenesis
(Springer Link, 2023)Dolomitization is an important diagenetic process observed in carbonate rocks ranging in age from Precambrian to Holocene. The formation of massive dolostone bodies has long been a challenge due to complex sedimentary and ... -
Two-stage bimodal volcanism in a Late Cretaceous arc/back-arc setting, NE Turkey: Constraints from volcano-stratigraphy, zircon Usingle bondPb and 40Ar/39Ar geochronology and whole-rock elemental and Sr-Nd-Pb isotope geochemistry
(Elsevier, 2023)The eastern Blacksea magmatic arc (EBMA) in the eastern Sakarya Zone (ESZ) provides an excellent opportunity to investigate birth of an extensional intra-arc and back-arc settings in the Late Cretaceous over the Early ... -
Post-variscan autochthonous cover in the eastern Sakarya zone, Turkey: evolution of the late carboniferous back-arc ocean to the triassic Karakaya Ocean
(Elsevier, 2023)The processes that caused removal of the upper Carboniferous to Permian sediments in the eastern Sakarya Zone, Turkey, are modeled by using of geochemical data and LA-ICP-MS U-Pb ages from detrital zircons. A felsic ... -
