Carbonate rocks in Antalya (Turkey) which have previously been called travertine should, because of their biogenic origin and deposition in a cool-water regime, be termed tufa. Tufas in Antalya are the products of physico-chemical and biogenic precipitation. In the biogenic process, precipitation was caused by decreasing partial pressure of CO, via photosynthesis of algae or bacteria. Following precipitation, the tufas under-went meteoric-vadose cementation and diagenesis. the Antalya tufa basin consists of horizontally-bedded carbonate sediments which are end products of a lacustrine depositional environment. However, a perched springline system has played an important role, serving as a starting point for calcium-carbonate precipitation. The morphology of tufa coastal cliffs is controlled by sea erosion. Thus, terraced morphology, except for small areas (e.g., Masadagi), should be considered a result of erosion. In this study, tufa deposits of Antalya were characterized with respect to mineralogy, sedimentology and surface morphology. In addition, for the future multidisciplinary needs (engineering and environmental) other aspects on tufa formation are discussed.

The importance of fractional crystallization and magma mixing in controlling chemical differentiation at Suphan stratovolcano, eastern Anatolia, Turkey Ozdemir, Yavuz; Blundy, Jon; Güleç, Nilgün Türkan (Springer Science and Business Media LLC, 2011-09-01) Suphan is a 4,050 m high Pleistocene-age stratovolcano in eastern Anatolia, Turkey, with eruptive products consisting of transitional calc-alkaline to mildly alkaline basalts through trachyandesites and trachytes to rhyolites. We investigate the relative contributions of fractional crystallization and magma mixing to compositional diversity at Suphan using a combination of petrology, geothermometry, and melt inclusion analysis. Although major element chemistry shows near-continuous variation from basalt to ...
Hydrothermal alteration products in the vicinity of the Ahirozu kaolin deposits, Mihaliccik-Eskisehir, Turkey Sayit, Isil Omeroglu; Günal Türkmenoğlu, Asuman; Sayin, S. Ali; Demirci, Cengiz (Mineralogical Society, 2018-06-01) The mineralogy, texture and composition of rocks associated with the kaolin deposits in the Ahirozu-Hamidiye-Ucbasli area, SE of Mihaliccik, Eskisehir, Turkey, were investigated. In the study area, Triassic, blue-green schists and serpentinized ultramafic rocks are exposed. Kaolinization occurs at the contact between a Triassic granitic intrusion and metamorphic rocks. Textural and mineralogical characteristics were identified by X-ray diffraction (XRD) and scanning electron microscopy-energy dispersive X-r...
Origin and significance of a quartz tourmaline breccia zone within the central anatolian crystalline complex, Turkey Demirel, Serhat; Göncüoğlu, Mehmet Cemal; Department of Geological Engineering (2004) The aim of this study is to investigate the petrography, geochemistry and evolution of quartz-tourmaline-rich rocks occurring in a wide breccia zone within the Late Cretaceous Kerkenez Granitoid (Central Anatolian Crystalline Complex (CACC), Turkey). The approximately 40-m wide main breccia zone has a NE-SW trend and is characterized by intense cataclastic deformation. The breccia zone can be traced several kilometers towards the west and generally occurs as tourmaline-filled faults and 1mm-30cm-thick veins...
Shear strength-suction relationship of compacted Ankara clay Çokça, Erdal (Elsevier BV, 2010-08-01) The relationship between shear strength and soil suction of compacted Ankara clay was investigated at different moisture contents. Soil samples were tested at optimum moisture content (w = 20.8%), drier than optimum (w = 14.8%, 16.8%, 18.8%) and wetter than optimum (w = 22.8%, 24.8%, 26.8%). Direct shear tests were performed. Soil suctions were measured by the filter paper method after direct shear tests. Direct shear tests and soil suction measurements were also performed on soaked samples. The soil suctio...
Diabase dykes from Bogazkale (Corum), Central Anatolia: Geochemical insights into the geodynamical evolution of the northern branch of Neotethys Balc, Ugur; Sayıt, Kaan (Elsevier BV, 2020-05-01) In the Bogazkale region (Corum, Central Anatolia), pieces of Neotethyan oceanic lithosphere are found in an ophiolitic melange. Within the melange, there are occurrences of isolated diabase dykes that intrude serpentinized and carbonatized ultramafics. The diabases are phaneritic, holocrystalline and equigranular, and consist of plagioclase and hornblende as the main primary mineral phases. They have all undergone low-grade alteration, to varying extents, as reflected by the presence of secondary minerals, ...
