Jeology, Mineralogy and Geochemistry of The Cu-Mo Deposit Issociated With The Şükrüpaşa İntrusion, Dereköy, Kırklareli

Abstract: In the Şükrüpaşa area studied, the rocks are made up of Mesozoic limestones, schist, calc-schist, and metasandstones which unconformably overlay a basement of metagranitic rocks and the intrusive rocks of Cretaceous age. The Şükrüpaşa intrusion forms apart of the Srednogorie -Istranca granitoid chain identified as the island- arc type plutonism.The mineralization in the study area occurs as pirometasomatic type in the contact zone between the intrusive and sedimentary cover rocks, and as disseminated, fine vein, and stuckwork types in the calc-alkaline magmatic rocks, mainly including granodioriteand tonalite. Major ore minerals are pyrite, chalcopryrite, molybdenite, and scheelite. Primary magnetite, bornite, pyrrhotite, Bi-minerals, sphalerite, galena, enargite, neodigenite, arsenopyrite, ilmenite, ilmenomagnetite, rutile, anatase, and psilomelane and secondary chalcocite, covellite, malachite, azurite, limonite andgoethite accompany to these minerals. The average contents of Cu and Moare 0.41 percent and 0.08 percent respectively and it was determined that the most important mineralizations are in associated withthe contact zone.
