(Elsevier, 2020)The Dagbasi Fe-Cu-Zn skarn mineralization developed along the contact between the block and lens shaped limestones of the Lower Cretaceous Berdiga Formation and the Upper Cretaceous Dagbasi Granitoid. the exoskam-type ... -
Silurian to Early Devonian arc magmatism in the western Sakarya Zone (NW Turkey), with inference to the closure of the Rheic Ocean
(Elsevier, 2020)The Rheic Ocean is the most significant Paleozoic ocean that detached peri-Gondwana terranes from the northern Gondwana margin throughout the closure of the Iapetus Ocean. the suture of the Rheic Ocean spreads from Mexico ... -
Melting of the juvenile lower crust in a far-field response to roll-back of the southern Neotethyan oceanic lithosphere: the Oligocene adakitic dacites, NE Turkey
(Elsevier, 2020)Late Cenozoic tectono-thermal events and associated magmatism in the Sakarya Zone (SZ) are still contested. Although documented in the western part of the SZ, thus far, no magmatic activity has been identified in the eastern ... -
