New weathering indices for evaluating durability and weathering characterization of crystalline rock material: A case study from NE Turkey
(Pergamon-Elsevier Science Ltd, 2015)There are several methods to characterize petrochemical properties of crystalline rocks. One method is based on the ionic model. In the model, large oxygen atoms of the rock-forming minerals are close-packed framework ... -
Determination of contamination levels of Pb, Cd, Cu, Ni, and Mn caused by former lead mining gallery
(Springer, 2016)In the present study, levels of metal contamination caused by former lead mining area were figured out. For this purpose, Pb, Cd, Cu, Ni, and Mn were determined not only in sediment samples taken from different places of ... -
Origin and metamorphism of corundum-rich metabauxites at mt. ısmail in the southern menderes massif, sw Turkey
(Wiley-Blackwell, 2012)The corundum-rich metabauxites, found at the northwest limb of an NESW-trending isoclinal recumbent fold at Mt. Ismail, are enclosed in thick-bedded platform-type marbles of Late Cretaceous age, surrounding the polymetamorphic ... -
Phytoremediation with plants for soils polluted by boron at Akdagmadeni pb-zn mining district and surroundings, Yozgat, Turkey
(Gazi Univ, 2016)The amount of elements in plants is important for biogeochemical explorations. In this study 28 plant species and soil samples were collected from boron deposit area in Akdagmadeni. Boron is determined in plants and soil ... -
Assessment of petrophysical surface data of the Harşit granitoid in Trabzon, in northeastern Turkey
(Birkhauser Verlag Ag, 2012)The Harşit granitoid in northeastern Turkey, comprises four separate granite units that are apparently unfoliated. The HarAYit granitoid was investigated here by using microstructural, petrofabric and anisotropy of magnetic ... -
A new pelagic conodont taxon of the central pontides (Turkey)
(Scientific Technical Research Council Turkey-Tubitak, 2016)The Hallstatt-type limestones in the Central Pontides yield abundant conodonts of the genus Gladigondolella ranging throughout the entire studied sequence and indicating Anisian to Early Carnian ages. Gladigondolella okayi ... -
K-Ar dating, whole-rock and Sr-Nd isotope geochemistry of calc-alkaline volcanic rocks around the GumuAYhane area: implications for post-collisional volcanism in the Eastern Pontides, Northeast Turkey
(Springer Wien, 2014)Volcanic rocks from the GumuAYhane area in the southern part of the Eastern Pontides (NE Turkey) consist mainly of andesitic lava flows associated with tuffs, and rare basaltic dykes. The K-Ar whole-rock dating of these ... -
Oxygen isotopic variations in modern cetacean teeth and bones: implications for ecological, paleoecological, and paleoclimatic studies
(Elsevier Science Bv, 2016)The oxygen isotope ratios (delta O-18) preserved in marine sediments have been widely used to reconstruct past ocean temperatures. However, there remain significant uncertainties associated with this method, owing to ... -
Triassic limestone, turbidites and serpentinite-the cimmeride orogeny in the central pontides
(Cambridge Univ Press, 2015)The basement of the Central Pontides, and by implication that of Crimea, consists of pre-Permian low-grade metaclastic rocks intruded by latest Permian-Early Carboniferous (305290 Ma) granitoids. Further up in the stratigraphic ... -
