Turkish Journal of Earth Sciences
The Karakoçan-Yoğunağaç (Elazığ) and Mazgirt-Dedebağ (Tunceli) travertines, which are related to thermal springs, are situated on the right-lateral strike-slip Karakoçan Fault Zone (KFZ) and left-lateral strike-slip Pamuklu Fault Zone (PFZ) in eastern Anatolia. The surface area of the travertines varies from m2 to km2. Morphologically, the travertines are classified as ridge, banded, and terrace types due to deposition in different ways, in the releasing/restraining bends of the KFZ and PFZ and on the segments of faults. The banded travertines were dated by U-series, and an age of 160,000 ± 76 years was determined in only one sample from the Mazgirt-Dedebağ …

Petrography And Geochemistry Of The Kamlial Formation, Southwestern Kohat Plateau, Pakistan: Implications For Paleoclimate Of The Western Himalayas, Kafayat Ullah, Mohammad Arif, Muhammad Tahir Shah
Turkish Journal of Earth Sciences
The Middle to Late Miocene Kamlial Formation that largely consists of sandstone and interbedded clay/mudstone sequences is exposed in the southwestern part of the Kohat plateau, which constitutes the westernmost extension of the Himalayan Foreland Basin. Whereas the sandstone is gray to brownish gray, fine- to medium-grained, and mostly thick-bedded, the interbedded clay/mudstone sequence is brownish gray to maroon red and occurs as continuous beds as well as lenses. Some mudstone/clay beds are bioturbated and seem to be pedogenic surfaces. Results of geochemical investigation of fresh (unaltered) representative sandstone and mudstone samples from three different sections of the formation in …

Rare Earth Element Geochemistry Of The Upper Permian Limestone: The Kanigorgeh Mining District, Nw Iran, Ali Abedini, Ali Asghar Calagari
Turkish Journal of Earth Sciences
The limestone of the Ruteh Formation of Upper Permian age in the Kanigorgeh district (northeast of Bukan, NW Iran) contains several layers and lenses of bauxitic ores. Mineralogical data show that this limestone consists of calcite and quartz as major and plagioclase, kaolinite, and hematite as minor mineral phases. Geochemical analyses reveal that the proportions of ?REEs (La-Lu) in this limestone vary from 35.28 to 160.78 ppm. The values of Eu and Ce anomalies (normalized to PAAS) of the limestone have ranges of 1.11-1.68 and 0.89-1.16, respectively. The high values of ?REEs; low values of Y/Ho; strong and positive correlations …
