| Tartalmi kivonat: | In the Mecsek Mountains (Tisza Unit, S Transdanubian, Hungary) an Aalenian-Bajocian rhythmic limestonemarlstone alternation crops out. Precise petrological analysis has not been accomplished on this formation and the origin of this characteristic bedding phenomenon has not been explained. Stable isotope values of carbonate samples show higher 8' 8 0 and 8L 'C values in limestone beds relative to marlstone beds. A correlation exists between the carbonate content and the stable isotope values. On the basis of this isotope data and other observations on the collected samples can be devised a depositional model of Komló Formation. The data suggest that production and/or dilution cycles may have formed the limestone-marlstone alternation; diagenetic overprint was only of minor significance. |
