def_strat_name_concepts {rmacrostrat} | R Documentation |
A function to retrieve the definitions for stratigraphic name concepts. By default, all stratigraphic name concept definitions are returned.
def_strat_name_concepts(strat_concept_name = NULL, strat_concept_id = NULL)

Stratigraphic name concepts consist of grouped strat_name
s which
represent the same geologic entity. This may be due to stratigraphic names
appearing in multiple reference maps or at multiple lithostratigraphic
ranks.
A data.frame
containing the following columns:
concept_id
: The unique identification number for the
stratigraphic name concept, which groups variant strat_name
s for same
geologic entity.
name
: The name of the stratigraphic name concept.
geologic_age
: The geologic age information assigned to the
stratigraphic name concept, as defined in the original reference in plain
text.
int_id
: The unique identification number of the
chronostratigraphic interval associated with the stratigraphic name
concept (see def_intervals()
).
b_int_id
: The unique identification number of the bottom
(oldest) chronostratigraphic interval associated with the stratigraphic
name concept (see def_intervals()
).
t_int_id
: The unique identification number of the top
(youngest) chronostratigraphic interval associated with the stratigraphic
name concept (see def_intervals()
).
usage_notes
: Notes on the current validity of the
stratigraphic name concept, in plain text.
other
: Other associated notes on the stratigraphic name
concept, in plain text.
province
: The provinces where the stratigraphic name concept
appears, in plain text.
refs
: The unique identification number of the reference from
which the stratigraphic name concept was sourced (see
def_references()
).
url
: The URL associated with the stratigraphic name concept,
where additional information, the source or contributing publication can
be found.
author
: The authors of the source reference.
