Magnetostratigraphic (re)calibration of the Paleocene/Eocene boundary interval in Holes 550 and 549, Goban Spur, eastern North Atlantic

A magnetostratigraphic reinvestigation of the Paleocene/Eocene boundary intervals in DSDP Holes 550 and 549, Goban Spur, has removed uncertainties associated with the previously published magnetostratigraphic information for these chronostratigraphically important sections. In Hole 550, levels assigned to nannoplankton zones NP4 and 5, previously considered to be of normal polarity, carry a reverse polarity characteristic magnetisation which is...
