From: Timing of the Brunhes-Matuyama transition constrained by U-series disequilibrium
Ages and paleomagnetic results vs depth, the vertical grey line marks the Brunhes-Matuyama transition determined after the paleomagnetic results (a) Isotopic ratios and ages determined using the standard 230Th/U approach and the new 234U/U0 ages, horizontal grey line is mean age for B-M obtained by Channel et al.36 (773 ka). (b) Paleomagnetic declinations, red circles are data from the 2.5 cm plugs, black diamonds from the 1.5 cm plugs, the core is reoriented so that the mean declination is along the N-S direction, dashed lines are the 0 and 180° expected dipole values. (c) same than (b) for paleomagnetic inclinations, dashed lines are the + 51° and −51° expected dipole value.
