Geological of Altıoluk (Alacakaya-Elazığ) environment and the rosso-levanto marbles

Magmatic, sedimentary and volcano-sedimentary units in the age range from Jura to Middle Eocene on the Southeast Anatolia Drifting Belt were affected by tectonic forces and deformation and tectonic traces were widely observed in the study area. Guleman Ophiolite is the oldest unit in the region, with unconformity over this unit, Lice Group and Maden complex. In the widespread ultramafic rocks of the Alacakağı area of Elazığ, advanced lithophyllite occurrences are observed, especially under the effect of tectonism along tectonic lines. Lisvenitler is interspersed with serpentine minerals (lizardite, chrysotile), talc, diopside and chromite minerals in serpentinized ultramafites. This mineral assemblage shows a high rate of reaction between magmatic roots and minerals in fluid existence. There are marble formations that offer different textures and colors settled along Lisbonites, along tectonic lines, and at longer distances. Mineralogical and chemical properties of the marble samples taken from the marble quarries opened at different stratigraphic levels of the study area were determined and the change and the reasons of these properties were examined. This study, prepared as a Master Thesis, covers the geology of the Altıolaya-Elazığ environment and the formation of Rosso-Levanto marbles. The geological, petrographic and chemical analyzes carried out indicate that these marbles are rock masses with calcite / micritic cemented tectonic breccia characterized by the accumulation of basic and ultramafic rock fragments and fragments, which are formed as a result of accumulation of rocks in the study area transported between large fault surfaces. The color varies depending on the rock components and hydrothermal solutions carried along fault fractures. The presence of hydrothermal fluids can be determined in the form of pyrite, malachite, azurite, native copper ore in the marble block or along the fracture zones.
