Geochemical investigation of Kurtyuvasi (Oltu - Erzurum) copper-gold mineralization

This master?s degree thesis which is being comprises some geological and geochemical researches of Inanmış (Oltu-Erzurum) Cu field. MTA has been proceeding geological research around Oltu-Narman-Tortum (Erzurum) district which host the study area, since 2004, in the context of ?Eastern Anatolian Polymetal Exploration Project?. The study area, located on the southern magrin of the Eastern Pontides, is within the topographic map sheet on the H47 a2. In the study area, from oldest to youngest, pre-Cretaceous and Cretaceous aged basic volcanics, lower and upper Cretaceous aged limestones, Eocene aged clastic rocks, and acid-basic rocks intruding basic volcanics are observed. The youngest unit in the field is Quaternary aged alluvium. Igneous rocks observed in the field have undergone intense alteration and mineralization. High Cu content and small amount of Au values detected from soul and rock samples, pervasive hydrothermal alteration, porphyry-textured acid and intermediate dykes, network of quartz ? of calcite vein-veinlets, brecciated structur and the presence of chalcopyrite and bornite ore minerals indicate that Inanmıs mineralization show many similarities to porphyry type Cu-Au mineralization.
