dc.description.abstractThe Attepe district consists of Precambrian, Lower-Middle Cambrian, Upper Cambrian-Lower Ordovician and Mesozoic formations. It contains several iron deposits and occurrences. Three types of iron-mineralizations can be distinguished in the area; (1) Sedimentary Fe-sulfide in Precambrian bituminous metapelitic rocks, and Fe-oxides in Precambrian metasandstones (STSO), (ii) vein-type Fe-carbonate and oxides composed of mainly siderite, ankerite and hematite including barite in Lower-Middle Cambrian metacarbonates of the Caltepe Formation (HICO), (iii) karstic Fe-oxides and hydroxides essentially in the Lower-Middle Cambrian metacarbonates and the unweathered Fe-carbonates (KIO). The latter type is more widespread and located at the upper parts of the most important mineable iron deposits like Attepe deposit. Oxygen-, carbon-, sulfur- and strontium-isotope studies have been performed on siderites and barites in the vein-type ores, and on calcites in the recrystallized Caltepe Limestones to investigate the sources and formation mechanism of primary ore-forming constituents. The delta C-13 values of siderites and calcites in limestones of the Caltepe Formation range from -10.10 parts per thousand to -8.20 parts per thousand, and from -0.8 parts per thousand to 2.30 parts per thousand. Both carbonate minerals show delta O-18 values between 17.50-18.30 parts per thousand and 16.20-23.00 parts per thousand, respectively. The delta C-13 and delta O-18 isotopic variations do not indicate any direct or linear relations between siderites and limestones. However, it is possible that the carbon and oxygen isotopic compositions of carbonate minerals could be changed to some extent, when limestones were subjected to hydrothermal processes or thermal alterations during metamorphism. The isotopic values of barites display 32.40-38.30 parts per thousand for delta S-34 and 12.20-14.70 parts per thousand for delta O-18. The strontium isotope ratios (0.717169-0.718601) of barites and the sulfur isotope compositions of barites and pyrites suggest that there are no direct linkages of ore-forming compounds neither with a magmatic source nor with sedimentary pyrite formations in the Precambrian bituminous shales of the Attepe formation. According to the field observations and the stable isotope data, siderites and ankerites should be formed by interaction between iron-rich hydrothermal fluids and Caltepe limestones, whereas isotope ratios of barites indicate that they were formed by mixing of sulfur-rich meteoric waters and deeply circulated hydrothermal solutions.
