Geochemical fingerprints of Late Triassic calc-alkaline lamprophyres from the Eastern Pontides, NE Turkey: A key to understanding lamprophyre formation in a subduction-related environment
(Elsevier Science Bv, 2014)The Eastern Pontides in NE Turkey is one of the major orogenic belts in Anatolia. in this paper, we report our new Ar-40/Ar-39 dating, mineral chemistry, major and trace elements and Sr-Nd-Pb isotopic analyses of the ... -
Geochemistry of the Turonian-Coniacian strata: New insight into paleoenvironmental conditions of the Tethys, Eastern Pontides, NE Turkiye
(Elsevier, 2023)The eastern part of the Sakarya Zone, known as the Eastern Pontides, is represented by a south-facing carbonate platform during the Late Jurassic-Early Cretaceous. The shallow marine carbonate sedimentation is masked by ... -
