Table T11. Age control points for Site 1151 datum events and sedimentation rates. Notes: LO = last occurrence, LCO = last common occurrence, B = base, FO = first common occurrence, T = top, * = diatom datums from Hole 1151A sediment. In Holes 1151C and C, these diatom datums were about 20 m shallower. Values in parentheses are from Holes 1151C and 1151D.
