More information can be found for the inputs for this function
using the definition functions (beginning with def_
).
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 (see def_strat_names()
).
liths
: A vector containing the unique identification
number(s) of the lithology(ies) represented within the outcrop shape
element (see def_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.
