Geological Timescale

pyrolite includes a simple geological timescale, based on a recent verion of the International Chronostratigraphic Chart [1]. The Timescale class can be used to look up names for specific geological ages, to look up times for known geological age names and to access a reference table for all of these.

from pyrolite.util.time import Timescale, age_name

ts = Timescale()

eg = ts.data.iloc[:, :5]  # the first five columns of this data table
