Notes: CN = ages derived from nannofossils, PF = ages derived from planktonic foraminifers, BF = ages derived from benthic foraminifers. u/c = unconformity. TD = total depth. MP = Marshall Paraconformity ("Green" horizon of industry interpreters), DLS = seismic downlap surface originally thought to be MP, B/M = Brunhes/Matuyama.
