Figure F20. Comparison of biostratigraphic events in Holes U1340A and U1341B used for stratigraphic correlation between sites. The percentages of Neodenticula seminae and Neodenticula kamtschatica were used as the primary biostratigraphic events. Various other biostratigraphic and magnetostratigraphic events are also included. BM = Brunhes/Matuyama. T = top, B = bottom. FO = first occurrence, LO = last occurrence, RI = rapid increase. APC = advanced piston corer, XCB = extended core barrel.
