FORMATION OF MAGNESITE MINERALIZATIONS FROM ESKISEHIR - ERENKOY, NORTHWESTERN TURKEY: A STABLE ISOTOPE STUDY

A new type of magnesite mineralization in Eskisehir - Erenkoey 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. Magnesite...

Zusammenfassung:A new type of magnesite mineralization in Eskisehir - Erenkoey 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 delta super(13)C and delta super(18)O stable isotope contents in order to determine the origin of mineralizing fluids. Results show mean values of -8.4 for delta super(I3)C and 31.9 for delta super(18)O. The CO sub(2) responsible for the mineralization is postulated to be a mix of atmospheric origin and decarboxylation of organic sediments.
