CRYSTALLISATION CONDITIONS OF IGNEOUS EPIDOTE IN A METAMORPHIC SOLE FROM NEOTETHYAN OPHIOLITIC MELANGE, KONYA, CENTRAL SOUTHERN TURKEY
Subhedral to euhedral epidote occurs with compositional and sector zoning in a metamorphic sole at the bottom of a Neotethyan ophiolitic mélange. The epidote is characterised by low Fe2O3 (5–8%) , high Al2O3 (26-30 %), and minor TiO2 (0.05-0.18 wt%), MnO (0.01-0.1 wt%) and MgO (0-0.12 wt%) contents. Petrographical and mineralogical characteristics and various aluminium-inhornblende geobarometry estimates suggest that the amphibole associated with epidote was possibly crystallized from a wet tholeiitic/alkaline magma between ~3.5-7 kb pressure conditions.
