Value
A data.frame
containing the following columns:
-
map_id
: The identification number of the outcrop shape element. -
source_id
: The identification number of the source geologic map. -
name
: The name of the outcrop shape element in the original (or modified) source geologic map. -
strat_name
: The geologic name(s) of the outcrop shape element. -
lith
: The lithology of the outcrop shape element as defined in the geologic map source in plain text. -
descrip
: Description of the outcrop shape element in plain text. -
comments
: Notes assigned to the outcrop shape element. -
macro_units
: A vector containing the unique identification number(s) for known Macrostrat unit(s) matched to the outcrop shape element. -
strat_names
: A vector containing the unique identification number(s) for known stratigraphic unit name(s) matched to the outcrop shape element (seedef_strat_names()
). -
liths
: A vector containing the unique identification number(s) of the lithology(ies) represented within the outcrop shape element (seedef_lithologies()
). -
t_int_id
: The identification number of the chronostratigraphic interval containing the top boundary of the outcrop shape element. -
t_int_age
: The top age of the chronostratigraphic interval containing the top boundary of the outcrop shape element. -
t_int_name
: The name of the chronostratigraphic interval containing the top boundary of the outcrop shape element. -
b_int_id
: The identification number of the chronostratigraphic interval containing the bottom boundary of the outcrop shape element. -
b_int_age
: The bottom age of the chronostratigraphic interval containing the bottom boundary of the outcrop shape element. -
b_int_name
: The name of the chronostratigraphic interval containing the bottom boundary of the outcrop shape element. -
color
: Recommended color for plotting the outcrop shape element based on the dominant lithology. -
t_age
: The estimated top age (minimum age) of the outcrop shape element, in millions of years before present. -
b_age
: The estimated bottom age (maximum age) of the outcrop shape element, in millions of years before present. -
best_int_name
: The best/most representative interval name for the outcrop shape element.
If sf
is TRUE
(the default), an sf
object is returned instead, with
the same columns plus a "geometry" column that contains the spatial data.
