SeymourIslandBins.rdata: Sampling bins approaching and covering the K/Pg boundary on Seymour Island, Antarctica

Description

Contains the sampling bins from Seymour Island from

• Macellari (1984), section D

• Witts et al. (2016), section A

Reference for stratigraphic heights is the composite section by Witts et al. (2016) with the K/Pg boundary at 1007.5 m. The bins from Macellari were correlated using the glauconite bed and the last ammonite occurrences at the K/PG boundary (Macellari 1984, p. 506 and 518, samples 401,402, and 403).

Usage

data(SeymourIslandBins)

Format

A list with two entries: One corresponding to the bins from Macellari (1984), the other to the bins from Witts et al. (2016)
