SeymourIslandAgeModels: Age models for the K/Pg boundary on Seymour Island, Antarctica

Description

Contains age models for the extinction at the K/Pg boundary on Seymour Island, Antarctica. Age models are based on

*the Stratigraphic height of the K/Pg boundary of 1007.5 m with an age of 66.04 Ma (Renne et al. 2013)

*magnetostratigraphy from Tobin et al. (2012) and ages from Gradstein et al. (2012), yielding an age of 66.389 Ma at the stratigraphic height of 934.4 m.

The stratigraphic height of a low deposition interval is assumed to be at 959.5 m based on section A from Witts et al. (2016).

Reference for stratigraphic heights is the composite section by Witts et al. (2016).

Usage

data(SeymourIslandBins)

Format

A list with entries named after the age models described in Hohmann (in preparation). Each of these age models consists of three vectors: 'age' and 'height' correspond to the age of deposition of a given stratigraphic height, and 'parameters' contains a description of the parameters used to generate the age models

Examples

# NOT RUN {
data("SeymourIslandAgeModels")
#Select age model B
my.agemodel=SeymourIslandAgeModels$B
#check parameters of age model
my.agemodel$parameters
plot(my.agemodel$age,my.agemodel$height,type='l',
  xlim=rev(range(my.agemodel$age)),xlab='Age [Ma]',ylab='Stratigraphic Height [m]')
# }
