Bulletin of the Mineral Research and Exploration
The Alpine Orogenic Belt with numerous porphyry Cu-Mo-Au mineralizations, starts from Eastern Europe continues through Turkey and the Caucasus and extends into Iran and Afghanistan. The study area of the Eastern Pontides is in this orogenic belt. Using fi eld and laboratory studies an attempt has been made to establish the origin of Yeşilbağlar, Kaban and Köprübaşı alteration zones in the Olur area (Erzurum). In the study area Early Eocene Coşkunlar volcanics and sub volcanic rocks have contact with the Oltu çayı volcanics of Early-Middle Jurassic. Alteration in the study area effects these Oltuçayı and Kaban volcanics. In the study …

Bulletin of the Mineral Research and Exploration
In this study, the geology, mineralogy, petrography, geochemistry, wall-rock alteration, ore-wall-rock relations, micro structural and textural relations in the copper-pyrite mineralization in Kızmehmet site (Ispendere-Malatya) and its vicinity were investigated. Ispendere Ophiolite (Jurassic-Lower Cretaceous), Yüksekova complex (Upper Cretaceous) and Kırkgeçit formation (Middle Eocene) crop out in the study area, which is located in Malatya-Elazığ region of the Eastern Taurus orogenic belt. Yüksekova complex is formed by Kuluşağı magmatites, Kapıkaya volcanics, Şişman magmatites and Harabe hill magmatites. Harabe hill magmatites cut all of the mentioned rocks in the complex and caused to form all of alteration types and different mineralizations in …
