  • Kokkinovrakhos Formation of central Greece;
  • Pindos zone, containing Mesozoic ‘deep water’ sediments;
  • Vardoussia sub-zone, consisting of carbonate rudites;
  • rudite-megabreccia facies;
  • carbonate rudite-megabreccia facies of the Vounikhora Member differs;
  • carbonate turbidite fan association;
  • Parnassos zone, consisting Mesozoic shallow marine carbonates


In the Kokkinovrakhos Formation of central Greece, poorly sorted, grain supported, lithoclastic carbonate rudites, megabreccias and olistoliths are associated with accumulations of fine-grained laminated carbonates. The laminae frequently exhibit grading and are interpreted as turbidity current deposits. The coarser grained rudites and megabreccias were also redeposited but were probably transported downslope by sliding and rolling, i.e. they are rock-fall deposits. Olistoliths were emplaced into deeper water by sliding. The fine-grained sediments of the laminated facies appear to have accumulated in pockets on an uneven sea floor during episodes of minimal rock fall activity. The sedimentary association is similar to that described from some modern fore-reef environments and is possibly characteristic of accumulations of sediment on, or near to, steep slopes adjacent to carbonate platforms, when episodes of tectonic activity lead to the shearing off and transport downslope of masses of well-cemented shallow marine carbonates.
