Appendix B. Additional Information on the Stratigraphy

Below are descriptions of the stratigraphy as published by Lalechos (1973) for the Kato Fighalia Sheet and by Papadopoulos (1997) for the Megalopolis Sheet. Observations on the paleontology were provided by Lalechos’ colleague, Dr. G. Christodoulou, and by Papadopoulos’ colleagues, Dr. S. Tsaila-Monopolis and Dr. V. Skourtsis-Coroneou.

Chert Series consists of thin-bedded multi-colored radiolarian cherts alternating (particularly in the lower part of the formation) with fine-grained sandstones. Upwards within the formation coarse-grained sandstones eventually dominate, yet are interbedded with radiolarian cherts, red marls, and limestones. Thickness of the Chert Series is approximately 100 m. Characteristic fossils are Pithonella, Globotruncanidae, Orbitolina, Lagenidae, Miliolidae, Textulariidae, and Radiolaria. The Chert Series is Upper Jurassic to Lower Cretaceous.

First Flysch consists of brown sandstone (ranging from fine to coarse grained) with interbeds of red marl, marly limestone, and microbrecciated limestones. Thickness ranges up to 100 m. Characteristic fossils are Aeolisaccus kotori, Moncharmontia appenninica, Marginotruncana marginata, Helvetoglobotruncana, Pithonella ovalis, Pithonella, Hedbergella, Heterohelicidae, Hedbergellinae, Orbitolina, Orbitolina concave, Nezzazata, Rotalipora, Pseudocyclammina, and Bacinella irregularis. First Flysch is Upper Cretaceous, Cenomanian to Lower Turonian.

Limestones are platy to bedded, multicolored, and with layers and nodules of red-black chert. Toward the top of this formation there are interbedded marls and red mudstones as well as sandstones and limestones. Thickness ranges up to 200 m. Characteristic fossils are Globotruncanita conica, Globotruncana linneiana, Globotruncanita stuarti, Globotruncana ventricosa, Globotruncanita elevate, Rosita fornicate, Pithonella ovalis, and Globotruncanidae. Limestones are Upper Cretaceous (Turonian to Maastrictian).

Flysch Transition Beds consist of alternating thin-platy to bedded limestones with layers and nodules of chert, and marly limestones. Progressively upward they transition into mudstones with interbedded marly limestones and massive sandstones. Thickness ranges up to 50 m. Characteristic fossils are Globigerina, Globorotalia, Discocyclina, Globotrucanita stuarti (reworked), and Globtruncana arca (reworked). Flysch Transition Beds are Paleocene to Eocene.
