Diagenetic to low-grade metamorphic evolution of clay mineral assemblages in Palaeozoic to early Mesozoic rocks of the Eastern Taurides, Turkey
Bozkaya, O; Yalcin, H (MINERALOGICAL SOC, 2004)Palaeozoic to early Mesozoic rocks of both autochthonous and allochthonous units of the Eastern Tauride Belt have different textural and mineralogical features related to their varying deposition regimes and thermal ... -
Geochemical characteristics of Yamadagi volcanics in central east Anatolia: an example from collision-zone volcanism
Yalcin, H; Gundogdu, MN; Gourgaud, A; Vidal, P; Ucurum, A (ELSEVIER SCIENCE BV, 1998)Neogene Yamadagi volcanic rocks consist of basaltic trachyandesite, trachyandesite, andesite, and dacite. The major- and trace-element chemistry indicates that the lavas are dominantly calc-alkaline and mildly alkaline in ... -
Mineralogical and geochemical characteristics of late Cretaceous bentonite deposits of the Kelkit Valley Region, northern Turkey
Yalcin, H; Gumuser, G (MINERALOGICAL SOC, 2000)Late Cretaceous bentonitic clays in the Kelkit Valley region of Turkey are composed of an alternation of limestone lenses and silicified tuff nodule-bearing pyroclastic rocks and their alteration products. Quartz, feldspar, ... -
New mineralogic data and implications for the tectonometamorphic evolution of the Alanya nappes, Central Tauride Belt, Turkey
Bozkaya, O; Yalcin, H (TAYLOR & FRANCIS INC, 2004)The Alanya Unit, consisting of three nappes, crops out in the Demirtas-Anamur area of the Tauride Belt and is related to the Alpine orogeny. The Mahmutlar nappe of Permian and pre-Permian age progressively evolved as ... -
Sepiolite-palygorskite from the Hekimhan region (Turkey)
Yalcin, H; Bozkaya, O (CLAY MINERALS SOC, 1995)Upper Cretaceous-Tertiary marine clayey-calcareous rocks of the Hekimhan basin contain fibrous clay minerals in significant amounts. Ophiolitic rocks in the provenance area have contributed the elements to form the clay ... -
Ultramafic-rock-hosted vein sepiolite occurrences in the Ankara ophiolitic melange, Central Anatolia, Turkey
Yalcin, H; Bozkaya, O (CLAY MINERALS SOC, 2004)A 2 m thick brecciated zone containing magnesian minerals is present at the contact of tectonites and cumulates. Tectonites below this zone comprise serpentinized orthopyroxenite and serpentinite. An alteration zone with ... -
Use of natural zeolite-supplemented litter increased broiler production
Eleroglu, H; Yalcin, H (SOUTH AFRICAN JOURNAL OF ANIMAL SCIENCES, 2005)The aim of this study was to ascertain the influence of natural zeolite, consisting mainly of clinoptilolite and mordenite, as a component of the litter material in broiler houses on the performance of the broilers and on ... -
Very low grade metamorphism of Upper Paleozoic-Lower Mesozoic sedimentary rocks related to burial and thrusting in the Central Taurus Belt, Konya, Turkey
Bozkaya, O; Yalcin, H (TAYLOR & FRANCIS INC, 2000)Metasedimentary and sedimentary rocks that represent the allochthonous Bolkardagi Unit crop out in the Central Taurus Belt. Devonian units include mainly slate, metadolomite, metadolomitic limestone, and metasandstone. ...
