Mixtures of biosiliceous and heterozoan-dominated carbonate deposits are commonly interpreted as recording cold-water polar or deep basinal conditions. However, a growing body of literature is documen...
The Early Cretaceous ammonites from the Hradiště Formation (Wernsdorfer Schichten in original concept) in the Czech part of the Silesian Unit of the Outer (Flysch)Western Carpathians are describe...
The playa-mudflat facies under investigation are found in the Gemerek Basin (Sivas, Türkiye). This Miocene basin is bordered by the Akdağ Metamorphics (Paleozoic) to the N-NW, the Elmalıda...
Medium-grade metamorphic rocks crop out over a large area under the Neogene sedimentary and volcanic rocks in the central Biga Peninsula in northwest Turkey. These Çamlıca metamorphics co...
A non-metamorphosed sedimentary sequence of Late Palaeocene-Eocene age exposed to the south of Dereköy Village (east of Denizli) was formerly interpreted as the uppermost part of the Menderes Mas...

Boralsilite, the first natural anhydrous Al-B-silicate, is a high-temperature phase in peg-matites cutting granulite-facies metapelitic rocks at Larsemann Hills, Prydz Bay, east Ant-arctica (type loca...
Accessory monazite crystals in granites are commonly unstable during amphibolite fa-cies regional metamorphism and typically become mantled by newly formed apatite-allan-ite-epidote coronas. This dist...
