Contemporary Velocity Field For Turkey Inferred From Combination Of A Dense Network Of Long Term Gnss Observations, Ali̇ İhsan Kurt, Ali̇ Değer Özbakir, Ayhan Ci̇ngöz, Semi̇h Ergi̇ntav, Uğur Doğan, Seda Özarpaci

Turkish Journal of Earth Sciences

The Anatolia?Aegean domain represents a broad plate boundary zone, with the deformation accommodated by major faults bounding quasi-low deforming units. First-order features of this deformation were obtained in the form of a GNSS-derived velocity field. During the last decade, the accuracy of velocity solutions was improved, and the expansion of continuous networks increased spatial resolution. Nonetheless, an accurate representation of the deformation field requires interstation distances much lower than the locking depth of nearby faults, which has not yet been satisfied. The basis for creating a precise and accurate velocity field is uniform processing of the time series recorded both …

Hyracoidea From The Middle Miocene Hominoid Locality Of Paşalar (Nw Turkey), Martin Pickford, Serdar Mayda, Berna Alpagut, Fatma Arzu Demi̇rel, Ayşegül Şarbak, Tümel Tanju Kaya

Turkish Journal of Earth Sciences

Previously available samples of Hyracoidea from Paşalar (MN 6, Middle Miocene), Turkey, have indicated the presence of Pliohyracidae at the site, but the material was too scanty for confident identification. The single upper molar, an upper molar ectoloph fragment and an ascending ramal fragment were too uninformative for determining the taxonomic identity of the fossils, although several names have been proposed in the literature. Additional fossils collected from Paşalar include upper and lower premolars, which help to tie down the affinities of this hyracoid. They are attributed to the genus Prohyrax, but were not named specifically, even though they are …
