Bulletin of the Mineral Research and Exploration
In Northwest Anatolia, widespread magmatism developed due to collision between Anatolide-Tauride platform and Sakarya continent during Late Cretaceous-Early Tertiary period. The granitoids in Biga Peninsula are products of post-collisional magmatism following the convergence of the northern branch of Neotethyan Ocean and developed in two different stages as Eocene and Oligo-Miocene. Eocene Karabiga, Güreci, Kuşçayır and Dikmen granitoids are granite and diorite-granodiorite; Oligo-Miocene Sarıoluk, Yenice, Kestanbol, Eybek, Evciler, Çamyayla and Alanköy granitoids are diorite, granodiorite, monzonite and Q-monzonite in composition. Metaluminous and peraluminous granitoids have similar geochemical variations and exhibit post-collisional geochemical signatures. Trace element patterns are almost similar to those …

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 …
