The Çöpler deposit is located about 120 km west of the city of Erzincan in central eastern Turkey, and it consists of a subeconomic porphyry-type Cu-Au mineralization overlain by paragenetically later low-sulfidation epithermal-style Au mineralization. The porphyry-epithermal mineralization is spatially related to middle Eocene intrusive rocks, which have been emplaced into a succession of Permian-Cretaceous metasedimentary and carbonate rocks within an ENE-WSW-trending structural window exposed in the northeastern part of the Tauride-Anatolide orogenic block. The intrusive suite at Çöpler consists of different phases of diorite porphyry which contain phenocrysts of plagioclase and hornblende±biotite, set in a groundmass of quartz and plagioclase. Major and trace element data suggest an I-type calc-alkaline magmatic affinity for the diorite porphyries with strong resemblance to magmatic rocks formed in continental arc settings.

Age and tectonomagmatic setting of the Eocene Copler-Kabatas magmatic complex and porphyry-epithermal Au deposit, East Central Anatolia, Turkey İmer, Ali; Creaser, Robert A. (2013-06-01) The Copler epithermal Au deposit and related subeconomic porphyry Cu-Au deposit is hosted by the middle Eocene Copler-KabataAY magmatic complex in central eastern Anatolia. The intrusive rocks of the complex were emplaced into Late Paleozoic-Mesozoic metamorphosed sedimentary basement rocks near the northeastern margin of the Tauride-Anatolide Block. Igneous biotite from two samples of the magmatic complex yielded Ar-40/Ar-39 plateau ages of 43.75 +/- 0.26 Ma and 44.19 +/- 0.23, whereas igneous hornblende f...
TIMING AND NATURE OF ALTERATION AND MINERALIZATION AT THE ÖKSÜT AU-CU DEPOSIT (KAYSERI, CENTRAL ANATOLIA) Yurdakul, Emrecan; İmer, Ali; Department of Geological Engineering (2022-6-29) The Öksüt high-sulfidation epithermal gold-copper deposit is hosted within the late Miocene Develidağ Volcanic Complex (DVC) in south-central Anatolia. Mineralization mainly occurs in two domains, the Keltepe and Güneytepe orebodies, where steeply-dipping and pervasively supergene oxidized breccia zones exploited funnel-shaped diatreme conduits within andesite porphyry. Emplacement of these breccias was largely controlled by sub-vertical faults with dominant normal-slip components. Mineralized breccias comp...
Geology of the Idis Dagı Avanos area Nevşehir Central Anatolia Köksal, Serhat (1997-01-01) İdiş Dağı-Avanos area is located on the northeast of Nevşehir, and is a part of the Central Anatolian Crystalline Complex. The basement rocks of the study area constitue? Mesozoic aged Aşıgediği Metamorphics, that represent the uppermost unit of the Central Anatolian Metamorphics and consist of platform type meta-carbonates. İdiş Dağı Syenitoid, composed of quartz syenite, alkali feldspar quartz syenite and quartz monzonite intruded the Aşıgediği Metamorphics, and generated contact metamorphic zones. Karahı...
Numerical Modeling of the 1939 Erzincan Earthquake Karim Zadeh Naghshineh, Shaghayegh; Askan Gündoğan, Ayşegül (null; 2019-06-26) Erzincan İli, Kuzey Anadolu Fay Hattı, Kuzey Doğu Anadolu Fay Hattı ve Ovacık Fayları arasında derin bir basen yapısı içerisinde yer almakta olup, dünyanın sismik aktivite açısından en yoğun bölgelerinden birisidir. Bölgenin sismotektonik ve jeolojik koşulları, 1939 (Ms~7.8) ve 1992 (Mw= 6.6) depremleri dahil olmak üzere bir çok tarihi ve aletsel dönem depremlerine sebep olmuştur. 1939 Erzincan depremi çok yıkıcı bir deprem olmakla birlikte, aletsel dönemden önceye denk geldiği için bu depreme ait kayıt bul...
Fractal Modeling of Outcrop Fracture Patterns in Alasehir Geothermal Reservoir Turkey Gürel, Emrah; Coşkuner, Yakup Berk; Akın, Serhat (2016-02-24) Alasehir geothermal area located in Gediz graben is the current high enthalpy geothermal target in Turkey. The geothermal system mainly produces from fractured Paleozoic Menderes metamorphics. In order to characterize the fractured reservoir formations, marble and schist outcrop fracture networks were identified and traced using image analysis software. Primary and secondary fracture histograms were developed and box counting method was used to calculate fractal dimension. It was observed that for both form...
