Figure 15. Marine-cemented rudist rubble in slope debris flow, Gaios harbor, Paxos.
Upper Cretaceous (Maastrichtian?) limestone. A higher magnification view of an intraclast in a deep-water debris flow. It contains shelf-margin rudist biosparite with complete occlusion of porosity by extremely early marine cements. Both the rudist fragments and marine cements were truncated during the formation of this clast. Examination of such deeper water intraclasts can provide considerable information about nearby platforms and their early diagenetic history--information commonly of great value to explorationists.
