BIOSTRATIGRAPHY AND SEDIMENTATION RATES

Lower Miocene to upper Pliocene zones are well represented in these cores, although some zones were combined because of the absence of marker taxa or apparent juxtaposition of datum events. Initial biostratigraphic "reconnaissance" of core-catcher samples also suggests that a few zones may be absent in the section.

Carysfort Reef - Tile 1 - Systematic Mapping of Bedrock ...

Coral reefs and reef rubble transmit acoustic energy poorly, thus obscuring seismic reflections that would identify underlying stratigraphic horizons or rock surfaces. The youngest pre-Holocene age recorded so far anywhere along the Pleistocene shelf-edge reef was obtained on a coral cored from the seaward face of the reef beneath Carysfort Reef.
