Features and Origin of Billurik Dere (Elazığ) Mineralizations

Mineralization of Billurik dere is located in and on the contact zone of granitic and dioritic magmatics of the Yüksekova complex. The mineralization which occur in the magmatic, emplaced along E—W striking tension fractures and of vein type in nature. The mineral assemblages of these veins are pyrite, chalcopyrite, sphalerite, galena, magnetite, specularite and some of these minerals are dominant ore minerals in some veins. The mineralizations which occur on the contact zones are contact type in nature and they bear additional minerals such as Cu-sulphosalts, Bi-sulphosalts and Ag-fahlore. The mineralizations are associated with serialization, kaolinization, silicification, tourmalinization and epidote formation. The mineralizations developed possibly during thrusting of the Keban metamorphics on the Yüksekova complex in a time span from Upper Cretaceous to Paleocene and related with the tectonic evolution of the area.
