Mineral Resources On-Line Spatial Data
Mineral Resources > Online Spatial Data
1) Coordinates: When samples were brought in for analysis, the submitter was required to include information about the sample for the database; descriptions, geocoding, and latitude-longitude coordinates. In the days before map digitizing boards and GPS units were common, the determination of coordinates from field sheets was a time consuming and error prone process. In order to facilitate the analysis of samples, a decision was made to allow submitters to enter the coordinates for the lower right (southeast) corner of the submitter's working field map on which the samples could be plotted, which was most commonly a 7.5' or 15' quadrangle map. In theory, the precise coordinates for these samples would be determined and added to the database at a later date. In practice, most of these precise coordinates were used in the USGS Open-File data releases but were never entered back into the PLUTO database. Therefore, the precision of coordinates in the PLUTO database varies from "good to the nearest second of latitude or longitude" to "good to the nearest 15 minutes of latitude or longitude".
2) Geocoding: The submission of sample descriptive information (geocoding) with samples was mandatory for some fields and optional for others. Therefore, the completeness of geocoding can vary. In addition, most geocodes were not checked for completeness, accuracy, or validity during data entry into the early databases. Therefore the database contains some incorrect and invalid codes.
3) Analytical Data: The samples in this data set were chemically analyzed by a variety of techniques over a period of time from the early 1960's to the present. The accuracy of the data varies with the analytical methodology and with the concentration of the element being analyzed.
4) Qualifiers: A qualifier such as "N" (less than the detection limit of the analytical method) or "G" (greater than the upper determination limit of the analytical method) accompanies some analytical data values. These qualifiers are defined as follows:
L = the element was detected by the technique but at a level below the lower limit of determination for the method. The value of the lower limit of determination is given in the adjacent data field.
G or > = the element was measured at a concentration greater than the upper determination limit for the method. The upper limit of determination is given in the adjacent data field.
N = the element was not detected at concentrations above the lower limit of determination for the method. The value of the lower limit of determination is given in the adjacent data field.
< = the element concentration was determined to be less than the lower determination limit for the method for this element. The value of the lower limit of determination is given in the adjacent data field.
When appropriate, these qualifying values appear in this data set as a separate field following each element. The attribute, or field name, for the qualifier field is always denoted by the letter "Q". For example, "N" in the "ASPPM_SQ" field followin an analytical data field labelled "ASPPM_S" would indicate the actual concentration of arsenic (AS) is less than the data value listed, which is the lower limit of determination for the method.
Each sample must have a valid and unique lab number Each sample must have a latitude and longitude Each sample must be identified as a rock Each analytical determination must be linked to a valid and unique lab number Each analytical determination must be identified by analyteIn addition, samples that could be identified as a processed derivative of a rock were removed from the data set. This included single minerals, mineral separates, heavy-mineral concentrates, rock coatings, insoluble residues, partial digestions, and leachates.
The rock samples in this data set were collected for a variety of purposes. Not all samples were subject to the same sample preparation protocol or the same analytical protocol.

The determination of coordinates from field sheets was a time consuming and error prone process. In order to facilitate the analysis of samples, a decision was made to allow samples to be submitted to the laboratory using only the coordinates for the lower right (southeast) corner of the submitter's working field map on which the samples could be plotted, which was most commonly a 7.5' or 15' quadrangle map. In theory, the precise coordinates for these samples would be determined and added to the database at a later date. In practice, most of these more precise coordinates were used in resultant USGS Open-File data releases or publications but were never entered back into the database.
When submitters reported locations as degrees, minutes, and seconds of latitude and longitude the accuracy should be within a few seconds. When submitters only reported locations as degrees and minutes the accuracy is only to the nearest minute. When submitters only reported the corner coordinates of their field map, the accuracy is only to the nearest 7.5 or 15 minutes.
2) Datum and Earth Ellipsoid or Spheroid: When coordinates were submitted from GPS receivers or when the source of the coordinates were known, the datum and spheroid are identified in two fields that accompany the locational coordinates. For the majority of the data, these fields are empty. Since most of the older coordinate data in the database were determined from published maps, the best assumption is that the appropriate datum and spheroid is the one most conmmonly used for those types of maps. In the United States, most field maps were USGS topographic maps that used NAD27 (1927 North American datum) based on the Clarke 1866 ellipsoid. Using the wrong ellipsoid or datum may result in a location that is offset by up to a couple hundred feet.
To create this data set, rock sample data were retrieved from the NGDB using the following criteria: 1) Each sample must have a valid and unique lab number; 2) Each sample must have latitude and longitude coordinates; and 3) Each sample must be identified as a rock. This data set was then examined to remove any samples that could be identified as a processed derivative of a rock. This included single minerals, mineral separates, heavy-mineral concentrates, rock coatings, insoluble residues, partial digestions, leachates, experimental or artificial samples, and some misidentified samples. An effort was made to fix incorrect or incomplete attributes. Several standardized sample descriptive fields were more completely populated using information previously found only in comment fields. The rock sample location and descriptive data were repackaged into a single table called tblRockGeoData.
Analytical data associated with these rock samples were retrieved from the NGDB using the following criteria: 1) Each analytical determination must be linked to a valid and unique rock sample lab number; and 2) Each analytical determination must be identified by analyte. This data set was then examined to remove determinations that were requested but not completed, determinations that could not be quantified due to instrumental interferences, and duplicate determinations. In addition, multiple variations of similar analytical methods were consolidated into a single method name by element. For example: data for 17 variations of emission spectrographic determination for zinc were all combined into a single field called ZNPPM_S. The analytical data were repackaged into 8 tables based upon the consolidated analytical methods: xtbMajorChem, xtbXrfChem, xtbNaaChem, xtbIcpaesChem, xtbIcpmsChem, xtbEsChem, xtbOtherChem, and xtbUnknownChem.
