CALCAREOUS NANNOFOSSILS FROM THE LATE JURASSIC EARLY CRETACEOUS OF NORTHWEST ANATOLIA, TURKEY Altıner, Sevinç (Wiley, 1993-12-01) Within the framework of an integrated stratigraphy, a detailed biostratigraphic study of Late Jurassic-Early Cretaceous (Tithonian-Valanginian) calcareous nannofossils was carried out in north-west Anatolia, Turkey.
CALCINATION BEHAVIOR OF SIVRIHISAR LATERITE ORES OF TURKEY KESKİNKILIÇ, ENDER; Pournaderi, Saeid; Geveci, Ahmet; Topkaya, Yavuz Ali (2011-03-03) This study investigated calcination behavior of one of the Turkish laterite deposits, which was recently found in Sivrihisar region. Representative limonitic laterite samples (1.26% Ni) taken from Yunusemre Karasivritepe and Kucuksivritepe location were first subjected to drying. Removal of chemically bound water and other volatiles were then studied, in detail. In the calcination experiments, temperature and time were the main experimental variables. Thermal treatment was conducted at the specific temperat...
Calcination characteristics of laterite ores from the central region of Anatolia KESKİNKILIÇ, ENDER; Pournaderi, S.; Geveci, Ahmet; Topkaya, Yavuz Ali (2012-10-01) Drying, calcination, prereduction, and smelting are the main steps in conventional crude ferronickel production. Industrially, these steps are conducted using the rotary kiln-electric arc furnace (RKEF) process. In this paper, calcination characteristics of Sivrihisar laterite ores from the Central Anatolia region are investigated. The extent of elimination of chemically bound water and other volatiles was studied by experiments conducted at various temperatures in the 250-800 degrees C range. Phase changes...
Metamorphic imprint of ridge subduction on the Neo-Tethyan ophiolites from the Saka Unit (Central Pontides, northern Turkey) Frassi, Chiara; Rebay, Gisella; Marroni, Michele; Sayıt, Kaan; Göncüoğlu, Mehmet Cemal; Ellero, Alessandro; Ottria, Giuseppe; Pandolfi, Luca (2020-09-01) The Intra-Pontide suture zone is the northernmost ophiolite suture zone exposed in the Anatolian peninsula. It consists of several variably deformed and metamorphosed tectonic units derived from the Neo-Tethyan IntraPontide oceanic (IPO) basin, and its continental margins that are currently represented by the Istanbul Zonguldak and the Sakarya terranes. Recent data suggests that the IPO was a wide supra-subduction oceanic basin whose closure began in the uppermost Early Jurassic by a north dipping intra-oce...
