Cenozoic Tectonics Of The Tuz Gölü Basin (Central Anatolian Plateau, Turkey), David Fernández-Blanco, Giovanni Bertotti, Tahsi̇n Atti̇la Çi̇ner
Turkish Journal of Earth Sciences
We present a new 3D geologic model for the architecture and Cenozoic tectonic evolution of the Tuz Gölü Basin, a major sedimentary basin in the Central Anatolian orogenic plateau. This model is grounded on 7 depth-converted seismic reflection profiles in combination with the analysis of backstripped subsidence curves, isochore maps, and a palinspastically restored cross-section. Two stages of basin formation are detected during Cenozoic times. During the Palaeogene, around 2 km of basement subsidence led to the development of a sag basin broader than the present basin in the absence of bounding faults. After a period of uplift and erosion, …
Fluctuations Of Sea Water Temperature Based On Nannofloral Changes During The Middle To Late Miocene, Adana Basin, Turkey, Manolya Sinaci
Fluctuations Of Sea Water Temperature Based On Nannofloral Changes During The Middle To Late Miocene, Adana Basin, Turkey, Manolya Sinaci
Turkish Journal of Earth Sciences
Some nannoplankton species are sensitive to water temperatures. While Coccolithus pelagicus and Reticulofenestra gelida indicate cooler water conditions, the genera Discoaster and Sphenolithus and Calcidiscus leptoporus are indicative of warmer water environments. This paper focuses on relative fluctuation of sea water temperatures during the Middle and Late Miocene, emphasised by cold and warm nannofossil changes in abundance in 2 wells. At the A-1 well in the Middle Miocene, the total abundance of cooler water species is 45%, while that of the warmer species is 3%. During the Late Miocene, the total abundance for cooler water species decreases to 34%; in …

Tragulidae (Artiodactyla, Ruminantia) From The Middle Miocene Chinji Formation Of Pakistan, Muhammad Akbar Khan, Muhammad Akhtar
Turkish Journal of Earth Sciences
The fossil record of the Siwalik tragulids remains poorly documented. The study of the tragulid material from the Chinji Formation allows the identification of 3 species: Dorcatherium minus, Dorcatherium majus and Dorcabune anthracotherioides. The tragulid assemblage is quite rich and Dorcatherium is the predominant taxon in the Chinji Formation of Pakistan. The fossils from the Chinji Formation of the Chakwal district, northern Pakistan, may document the first appearance of the 3 tragulid species in the Lower Siwaliks. The selenodonty and palaeoecology of the Siwalik tragulids are also discussed.
