Özet

A new type of magnesite mineralization in Eskisehir Erenköy in northwestern Turkey is reported. The mineralization is located in the Izmir - Ankara suture zone, associated with ultramafic rocks which lie on top of metamorphites. The deposits are heavily deformed due to tectonic effects. Magnesites have been analyzed for their δ13C and δ18O stable isotope contents in order to determine the origin of mineralizing fluids. Results show mean values of-8.4 for δ 13C and 31.9 for δ18O. The CO2 responsible for the mineralization is postulated to be a mix of atmospheric origin and decarboxylation of organic sediments.
