Comment:
The chronology was initially derived from micropaleontology and refined by calibration of Sr isotopes from the carbonate fraction of a selection of samples (Pierce et al., 1989, doi:10.2973/odp.proc.ir.121.1989) (IPGP-Lab data), using the reference curve of Mc Arthur et al. (2001, doi:10.1086/319243)
