Figure F41. Tentative summary correlation between lithostratigraphic units, seismic sequences, biostratigraphic hiatuses, and ages at Site 1128. The 'IC_' horizons, derived from the local upper continental rise seismic interpretation, are shown in relation to the slope and shelf seismic stratigraphy (sequences defined in Feary and James, 1998, reprinted as Chap. 2) correlated using biostratigraphic data.
