Abstract: Çamoluk (Burdur) iron-manganese mineralizations are found in the Middle Triassic-Liassic(Jurassic)Dutdere limestone. The mineralizations are situated in Akpınarkale Tepe, Kulübe Tepe andElmaçukuru locations. The iron-manganese mineralizations have thicknesses ranging from 0.6 m to 2 m andare seen generally cutting limestones in lenticular and normal vein forms. Mineral assemblage consists ofpyrolusite, psilomelane, cryiptomelane, hausmannite, hollandite, coronadite, chalcophanite, todorokite,braunite, manganite, pyrite, limonite (goethite), hematite, barite, quartz, cristobalite, calcite, chlorite,mica/illite, jarosite, and feldspar.In the iron-manganese occurrences, average composition is 30.51 % Fe O ,23.60 % MnO and 10.07 2 3% SiO . It was determined that the iron- manganese occurrences in the study area have high amounts of Ba, Sr, 2As, Zn, Pb, and Sb contents. Ba and Sr contents range between 0.4 % and 36.1 %, averaging 4.9 %, between0.01 % and 0.9 %, averaging 0.1%, respectively. Findings such as epigenetic vein form, mineral assemblage, higher trace element contents, and BaSr are significant evidences of a hydrothermal-metasomatic origin.
