Figure 14. Shelf intraclasts in a slope debris flow deposit, Gaios harbor, Paxos.
Upper Cretaceous (Maastrichtian) limestone. Intraclasts also are common in shelf-margin and slope limestones. These reworked grains include marine-cemented rudist reef material as well as finer-grained, back-reef and/or upper slope carbonate fragments. All have been reworked into basinal deposits by turbidity currents and debris flows. Intraclastic slope deposits (and slope-derived basinal limestones) commonly have a more diverse or polymict assemblage of grain lithologies than do most coastal or open shelf deposits.
