Database fields in table polygons

Mineral deposit areas described as polygons rather than points. Applies to antimony resources only.

gid
Record ID
(Site identification)
Unique identifier of the record in this database
dep_name
Area name
(Site identification)
Name of the area in which deposits may occur.
mineral
Critical mineral
(Commodities)
Mineral, raw material, or product that can be bought or sold. In this database, the mineral commodity or commodity group is one which is considered critical to the United States economy and (or) security as of 2017. These critical mineral commodities have important uses and potentially unreliable supply.When multiple critical minerals and (or) commodities occur at a location, there is no significance to the order in which they are listed.
dep_type
Deposit type
(Site characteristics)
Generalized mineral-deposit type in which a critical mineral or commodity occurs. A classification used for a mineral deposit based on genetic and physical characteristics such as how the deposit formed, inherent value (tonnage and grade), mining and beneficiation methods that can be used to develop a deposit, and the remediation that must be done to minimize environmental impacts of mining. Many critical minerals may be produced as coproducts or byproducts from mineral deposits, thus some deposit types are listed because they could contain critical minerals. If the deposit type was unknown, the value was listed as Deposit type unclassified.
latitude
Geographic latitude
(Geographic location)
Geographic location of the centroid of the polygon north or south of the equator reported in decimal degrees (WGS84). Negative values indicate latitudes south of the equator.
longitude
Geographic longitude
(Geographic location)
Geographic location of the centroid of the polygon east or west of the prime meridian reported in decimal degrees (WGS84). Negative values indicate longitudes west of the prime meridian.
location
Location
(Geographic location)
Description of the general location of a mine, mineral deposit, district, or region associated with a critical mineral commodity. The location is typically a country, but in some cases, the location is a geographic setting, for example; the Atlantic Ocean.
loc_detail
Location detail
(Geographic location)
An additional description such as a State, region, Province, department, or adjacent country that expands the description of the Location field.
geom
Geometry
(Geographic location)
Machine readable geometrical description of the location.
