| contents | This database is a compilation of studies published and unpublished quantifying calcareous nannofossils absolute abundances using Geisen et al. (1999) random-settling calibration. The data are ranging from Sinemurian (Lower Jurassic) to Quaternary. They were made on DSDP-ODP-IODP deep sea drilling, land sediment cores or, in most cases, land outcrop sections samples. Calcareous nannofossil accumulation rates (NAR) were calculated or updated by estimating sedimentation rates following sub-stages and biozones durations provided by Gradstein et al. (2012) or astrochronology when possible. In most sites, there were no indication of the dry bulk density (DBD), hence a type value was selected. This parameter is not critical for NAR calculated from land outcrop section samples (see Suchéras-Marx et al., 2014 Marine Micropaleontology). The results of the compilation is published in Suchéras-Marx et al., 2019 Biogeosciences. |
