Stable isotopes from ODP Hole 130-806B (Fig. 1), supplement to: Berger, Wolfgang H; Bickert, Torsten; Wefer, Gerold; Yasuda, Memorie K (1995): Brunhes-Matuyama boundary: 790 k.y. data consistent with ODP Leg 130 oxygen isotope records based on fit to Milankovitch template. Geophysical Research Letters, 22(12), 1525-1528


The age of the Brunhes-Matuyama boundary, until recently taken as 730 k.y. in standard time scales for the Quaternary (e.g., Imbrie et al., 1984; Prell et al., 1986, doi:10.1029/PA001i002p00137) and in Ocean Drilling Program results (Kroenke et al., 1991, doi:10.2973/; Shackleton et al., 1992 doi:10.2973/ has been revised to between 780 k.y. and 790 k.y., based on both orbital tuning of oxygen isotope data (e.g., Shackleton et al., 1990) and on new 40Ar-39Ar dates on volcanic rocks (e.g., Baksi et al., 1992, doi:10.1126/science.256.5055.356). We apply the revised chronology to an oxygen isotope record for Ontong Java Plateau (ODP Leg 130, western equatorial Pacific). Using this time scale, we find excellent agreement between the record and a template based on orbital forcing. The equation for the template is
