Mineralogical, petrographical and geochemical characteristics of plutonic rocks in the Çolakli (Elaziğ) environment

The studied area covers an area about 130 sg.km.s in the Çolaklı (ELAZIĞ) environment. The units of studied area from the oldest to the youngest; Upper Cretaceous Elazığ Magmatics, Middle Eosen-Upper Oligocene Kırkgeçit Formation, Upper Miocene-Lower Pliocene Karabakır Formation and Plio-Quaternary Palu Formation are exposed. In the studied area, the Elazığ Magmatics is represented by plütonic rocks such as granite, granodiorite, tonalite, diorite, quartz diorite; subvolcanic rocks such as microdiorite and aplite. Kırkgeçit Formation covers an angular unconformity Elazığ Magmatic sand this formation consists of sandstone and marls. Karabakır Formation comprising basalts overlap on older units with an unconformity. Palu Formation composed of terrestrial conglomerate is the youngest unit in the studied area. According to the geochemical analysis results, it defined that this magmatic rocks have subalkaline characteries and I-type granitoid plotted volcanic arc granitoids (VAG) and syn-collision granitoids (Syn-COLG). The intrusive rocks in studied area belong to Elazığ Magmatics are products of island arc magmatism. Key Words: Plutonic Rock, Petrography, Volcanic Arc, Elazığ Magmatics, Çolaklı, Elazığ.
