Properties of kaymaz listvenitic gold deposit and an approach to genesis of Kaymaz (Eskişehir) gold deposit

The study area is located in Central Anatolia, where Paleozoic and Mesozoic age metamorphic rocks andthe overlying serpentinites of the Tavşanlı Zone crop out. These rocks are cut by Eocene Kaymaz Granite. Mineralizations located in Damdamca, Karakaya ve Küçük Mermerlik locations are improvedwithin the serpentinites and quartz-schist unit in Kızılağıl location. In all this mineralizastions, the lithological control was important, as well as structural control. The distincly developed mineralization areas are generally regarded as similar. Evolution of the rock units in mineralization fields is developed as, in turn, (1) carbonated stage developed before or during the first stage hydrothermal phase, (2) ore-bearing first hydrothermal stage, (3) second hydrothermal stage lacking of ore minerals, (4) finally supergene stage. The metalic mineral, chromite, has a pre-mineralization origin. Generally, the main paragenesis of ore-bearing first hydrothermal stage contains magnetite, millerite, pentlandite, nickeline, arsenopyrite, marcasite, pyrite, bravoite, native gold, native silver; while the paragenesis of supergene stage is represented by presence of hematite, pyrolusite, gothite, limonite, lepidocrocite, chalcosine, covelline.
