| Popis: | Zebra dolomites and carbonate - hosted Au - Ag - Zn +/- Pb deposits of Maden village is located in the shelf type carbonate rocks of the Bolkar Mountains. The Zebra dolomite (ZD) locally form and there is no evidence for relation between dolomitization and mineralization. Maden village ZD is characterized by parallel light and dark bands that have similar mineralogy and chemistry by petrographic and SEM + EDX investigation. The delta C-13 (V - PDB) composition of the Zebra dolomite from 2.59 parts per thousand to 2.72 parts per thousand and the delta O-18 (V - PDB) values of the Zebra dolomite from -11.39 parts per thousand to -14.88 parts per thousand. These isotopic values show that the source of oxygen and carbon was derived from marine carbonates and freshwater carbonates. Fluid inclusion studies on Zebra dolomite show homogenization temperatures of 80 degrees C - 180 degrees C. Based on petrographic, isotope values and fluid inclusion study, we can say that the dolomitization occurred during the late diagentic conditions prior mineralization. |
