View/edit a dataset - chronostratigraphy

This page allows you to view all the information for a dataset, i.e. for a set of events and the intervals that they define, including the definitions of the basal events and the data used to set their age. The columns are also plotted. See the introduction page and the notes on table creation for more information

6319FAD Morozovella aragonensis52.4584Defines P7 (=E5) base. Berggren and Pearson (2005), which is same chron-age calibration as Berggren et al. (1995a) -- ’Morozovella argonensis’ FAD is recorded in North Atlantic Hole 550, North Pacific Shatsky Rise Hole 577 and in Chron C23r in South Atlantic (Walvis Ridge) Hole 527. Their 52.3 Ma age is at Chron C23r.1 on their polarity scale. [NOTE: The Wade et al. (2011) table based on Berggren-Pearson (2005) lists the same 52.3 Ma, which suggests they didn’t convert to the chron-ages of the GTS04 magnetic scale.]
6326LAD Morozovella velascoensis55.1484DASH (but Wade requested J.Ogg to remove "dash" via e-mail 18July2011) -- Wade et al. (2011) projects as 54.9 Ma relative to GTS04 polarity chrons, therefore at Chron C24r.61 (used here). Berggren and Pearson (2005), puts this LAD 0.2 myr higher than Berggren et al. (1995a) -- This LAD is recorded in younger part of Chron C24r in Hole 577 and in mid-C24r in Hole 577 (at 81.98 m). However, paleomagnetic data (Bleil, 1985, DSDP Leg 86: 449, Fig. 7b) suggests a hiatus occurs between ~82m & 83 m in Hole 577, which would have the effect of depressing (rendering older) the HO of ’M. velascoensis’. The HO of ’M. velascoensis’ in Hole 577 is in Nannofossil zone CP8 (=NP9) (Monechi, 1985: 310, Table 5) which supports interpretation of hiatus in Hole 577, because the LO of ’M. valascoensis’ is in Nannofossil Zone NP10. Furthermore, Monechi (1985: p.307) indicates absence of extremely condensed sedimentation across the Paleocene/Eocene boundary interval. Essentially, it is not yet possible to position this LAD proportionally within the long Chron C24r.

Column mock-up

This column mock-up plot is a simple plot of the data to allow visual comparison with the output from TimeScale Creator

The data plotted here are the columns from the chronostratigraphy dataset for the interval 0 - 500 Ma

The all events column is an optional extra column showing the interval tops and bases as well as the other events in the dataset. This does not correspond to a TSC column, but is useful for checking data.
