<idAbs>Mineral resource occurrence data covering the world, most thoroughly
within the U.S. This database contains the records previously
provided in the Mineral Resource Data System (MRDS) of USGS and the
Mineral Availability System/Mineral Industry Locator System
(MAS/MILS) originated in the U.S. Bureau of Mines, which is now part
of USGS.
The MRDS is a large and complex relational database developed over
several decades by hundreds of researchers and reporters. While
database records describe mineral resources worldwide, the
compilation of information was intended to cover the United States
completely, and its coverage of resources in other countries is
incomplete.
The content of MRDS records was drawn from reports previously
published or made available to USGS researchers. Some of those
original source materials are no longer available.
The information contained in MRDS was intended to reflect the
reports used as sources and is current only as of the date of those
source reports. Consequently MRDS does not reflect up-to-date
changes to the operating status of mines, ownership, land status,
production figures and estimates of reserves and resources, or the
nature, size, and extent of workings. Information on the
geological characteristics of the mineral resource are likely to
remain correct, but aspects involving human activity are likely to
be out of date.</idAbs>
<idPurp>This digest of the complex mineral resources database is intended
for use as reference material supporting mineral resource and
environmental assessments on local to regional scale worldwide.</idPurp>
<idCredit>Hundreds of people have contributed to the development of MRDS and
MAS/MILS over several decades. The present digest owes much of its
coherence to Bill Ferguson, Bruce Lipin, and Paul Schruben of USGS.</idCredit>

<suppInfo>Current status: As of 2011, USGS has ceased systematic updates to
MRDS, and is working to create a new database, focused primarily on
the conterminous US. For locations outside the United States, MRDS
remains the best collection of reports that USGS has available. For
locations in Alaska, the Alaska Resource Data File remains the most
coherent collection of such reports and is in continuing
development.
A small number of records (about 600) were updated slightly to
support USGS studies in the western U.S. related to a land use
change proposed by the Bureau of Land Management.</suppInfo>

<measDesc>Positional information is highly variable. In the best cases
this information was provided by plotting the location on a 7.5
minute topographic map, however many records were located on
the basis of published reports containing imprecise or scant
information on the specific geographic location. Approximately
4000 records have no reliable geographic coordinates, although
about 114 of those have other locational information systematic
enough to warrant placement within the controlled vocabulary

<stepDesc>Conversion of MRDS and MAS/MILS for use as a combined minerals
database within the Oracle relational database management system
proceeded under the general supervision of Bruce Lipin of USGS.
Review of many database fields resulted in significant
simplification, harmonization among records within these databases
and between the databases, and elimination of duplicate records.
The resulting relational database is currently maintained by
William Ferguson under the supervision of Paul Schruben.
This transition occurred from approximately 1996 through 2004.</stepDesc>

<stepDesc>Select fields and tables from the Oracle RDBMS are extracted using
the script pull.php to produce local copies of the tables
containing only those fields needed to produce the current digest.
The script combine.php draws data from these local tables to
create a single monolithic table with one row per mineral resource
record.
At this writing a number of corrections are made to the data given
for the form of orebodies. These changes include the elimination
of the useless value "SEE DEPOSIT DESCRIPTION COMMENTS", the
elimination of empty parentheses from most records, replacement of
the abbreviation 'IRREG' with the more common complete value
'IRREGULAR', and especially a complex analysis of most values
originating in the MAS/MILS database. These changes are described
by the script orebody-fix.php.
Additional modifications are made to the geographic locations of
about 4300 records whose coordinates are given in the source
database as the South Pole. These coordinates are replaced with
NULL values in the current database. The data selection software
in the current distribution web site allows some of these records
to be retrieved because some of the records contained additional
information linking them to specific geographic areas. These
changes are carried out by the script place-fix.php.
Information about host rocks and associated rocks was subject to
additional correction using the SQL statements in fix-rock.php.
This table is used to create the GIS shapefiles and other formats
available for download.</stepDesc>

<attrdef>Production size. A single character value.
A broad characterization of the magnitude of production at the site.

Modern specialists would prefer that such a categorization take into account the type of deposit and commodity at the site, but there is no evidence that approach was taken in assigning values to this field.</attrdef>

<edomvd>Metamorphic Rock &gt; Gneiss

or lenticles of granular minerals alternate with bands or
lenticles in which minerals having flaky or elongate prismatic
habits predominate. Generally less than 50 percent of the
minerals show preferred orientation.</edomvd>
