Trace element, Nd-Hf-Pb isotope geochemistry, and zircon U-Pb geochronology of the Baskil Dikes (Elazığ, Eastern Türkiye): Tracing Late Cretaceous continental arc magmatism in the Southern Neotethys Sayıt, Kaan; Ural, Melek; KORALAY, OSMAN ERSİN; Göncüoğlu, Mehmet Cemal (2026-06-01) During the Late Cretaceous, the dual subduction within the Southern Neotethyan domain resulted in the formation of an intra-oceanic arc complex (Yüksekova Complex) as well as an Andean-type continental arc characterized by...
Climate change drove Late Miocene to Pliocene rise and fall of C4 vegetation at the crossroads of Africa and Eurasia (Anatolia, Türkiye) Meijers, Maud J.M.; Mikes, Tamás; Rojay, Fuat Bora; ÇUBUKÇU, HÜSEYİN EVREN; Aydar, Erkan; Lüdecke, Tina; Mulch, Andreas (2026-05-12) Life on Earth has been capitalizing on the C3 photosynthetic pathway for 2.8 billion years. However, in the world's grasslands that emerged since the Paleogene, C4 vegetation expanded dramatically between 8 and 3 Ma in res...
Geochemical and palaeontological insights into Middle Triassic Intra-Pontide ocean island fragments: Elmadağ Olistostrome, Central Anatolia Sayıt, Kaan; OKUYUCU, CENGİZ; Tekin, Kagan; TUNCER, ALAETTİN; Akbaª, Melikan (2026-05-08) The Late Cretaceous closure of the Neotethyan Intra-Pontide Ocean generated mélanges in front of southward-advancing nappes. These include the Elmadağ Olistostrome, which consists of blocks embedded in a Coniacian (Upper C...
Thermal performance improvement of plant-based fabrics via pyrophyllite impregnation: an environmentally friendly approach to geocomposite insulation materials Aykasım, Devin; Toksoy Köksal, Fatma; Kılıç, Atilla (2026-05-04) Pyrophyllite is a mineral known for its chemical inertness, thermal stability and low thermalconductivity. Such properties are making it a suitable material for modern and advancedinsulation technologies. The study evaluat...
