What does this data set describe?

Title:
Geochemistry of rock samples from the National Geochemical Database
Abstract:
This data set contains geochemical data for rock samples collected by U.S. Geological Survey (USGS) personnel and analyzed either in the analytical laboratories of the Geologic Discipline of the USGS or by contract with commercial analytical laboratories. These data represent analyses of rock samples collected in support of various USGS programs. In addition to recent data, this data set includes archived geochemical data originally entered into the in-house Rock Analysis Storage System (RASS) database (used by the Geologic Discipline from the mid-1960's through the late-1980's) and the in-house PLUTO database (used by the Geologic Discipline from the mid-1970's through the mid-1990's). All of these data are maintained in the Oracle-based National Geochemical Database (NGDB). A retrieval from the NGDB was used to generate this data set.

Why was the data set created?

These data may be useful for a variety of geochemical studies; including mineral resource evaluation, defining geochemical baseline values and statistics, petrologic studies, geological mapping, and medical geology.

How was the data set created?

  1. From what previous works were the data drawn?
  2. How were the data generated, processed, and modified?
    Date: 2008 (process 1 of 2)
    The data were generated by the Geologic Discipline analytical laboratories of the U.S. Geological Survey over several years, beginning in the early 1960s. Upon completion of the chemical analysis, the data were stored in the RASS database (1963 to 1987), the PLUTO database (1979 to 1997), or the specific commercial laboratory-information-management software (LIMS) used by the USGS analytical laboratories (1996 to present). Data from all three sources were combined, reformatted, and standardized into the Oracle-based National Geochemical Database (NGDB).

    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.

    Correction of locations in 9,527 records (about 2.3% of the total records), deleted locations for 17 records for which sufficient location information could not be found.

    The locations that were corrected consisted of the following types of problems:

    1. records where longitude and latitude values were switched (i.e., Samples from North Carolina that plotted in Greenland, samples from Ethiopia that plotted in the Mediterranean, etc.). Records were fixed by checking original paperwork, replacing the coordinates, and confirming the correct location by plotting in Google Earth.

    2. records where at least one of the latitude/longitude values had the wrong +/- sign (i.e. Samples from Chile that plotted in the North Atlantic, Samples from Colorado that plotted in China). Records were fixed by checking original paperwork, replacing the offending coordinate, and confirming the correct location by plotting in Google Earth.

    3. records where at least one of the latitude/longitude values had been obviously mis-entered. (i.e. Samples from California that plotted in the Atlantic because the longitude had been enter as -19 for the entire job rather than -119, a single Nevada Wilderness sample in a job where all latitudes were 39°N except for 1 @ 79°N). Records were fixed by checking original paperwork, replacing the offending coordinates, and confirming the correct location by plotting in Google Earth.

    4. records where the coordinates plotted samples in places that were grossly incompatible with the listed State or Country location (i.e., Samples identified as from India that plotted in Indonesia, Sample identified as from Massachusetts that plotted in the southern Pacific Ocean). Records were fixed by checking original paperwork, plotting confirmed locations in Google Earth, and either changing the coordinates or the State/Country identifiers to match the confirmed locations

    5. records where the coordinates plotted outside of the U.S. and the State & Country fields were blank. Records were fixed by checking original paperwork to confirm the location and then either fixing coordinates or adding the correct Country value. Locations were confirmed using Google Earth.

    6. records where the coordinates were grossly in error and no better coordinates could be found. Records were fixed by changing the offending latitude/longitude coordinates to [NULL]. This case was actually very rare and was only used for 17 records. Had these 17 records been identified previously, they would not have been included in the database.

    In all cases, the corrected records now have the best coordinates that could be found and have the Country, and where appropriate, the State field values completely populated. Only values in the tblRockGeoData table were affected by this modification. Person who carried out this activity:

  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    The historical geochemical databases of the Geologic Discipline in the USGS were created with the intent of storing data predominately for regional projects. The new combined National Geochemical Database is an agglomerate of data from projects that had differing analytical needs and that ranged in scale from studies of an outcrop to reconnaissance surveys of an entire state or country. Initially, the intended user of the data was the original submitter or associated project personnel, and the primary means of publicly releasing data were hardcopy USGS reports, as well as professional journals. Within this paradigm, some decisions were made which have affected the completeness and accuracy of the attributes within the database.

    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.
  2. How accurate are the geographic locations?
    1) Coordinates: Most of the more recently submitted samples were located using GPS receivers. The locations determined by GPS should be accurate to the nearest latitude or longitude second. Older sample locations were determined primarily from USGS topographic maps of various scales. Sometimes these coordinates were determined directly from the original maps using a digitizing board. In other cases, a clear overlay with a coordinate grid was used to visually estimate the sample position on the map. The positional accuracy is dependant on the scale of the map from which the determination was made as well as the care taken by the individual(s) who plotted the sample or who made the coordinate determination. Unfortunately, some location coordinates were not carefully determined.

    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.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    This data set provides chemical data for Ag, Al, As, Au, B, Ba, Be, Bi, Br, Ca, Cd, Ce, Cl, Co, Cr, Cs, Cu, Dy, Er, Eu, Ga, Gd, Ge, F, Fe, Hf, Hg, Ho, I, In, Ir, K, La, Li, Lu, Mg, Mn, Mo, Na, Nb, Nd, Ni, Os, P, Pb, Pd, Pr, Pt, Rb, Re, Rh, Rn, Ru, S, Sb, Sc, Se, Si, Sm, Sn, Sr, Ta, Tb, Te, Th, Ti, Tl, Tm, U, V, W, Y, Yb, Zn, Zr, and forms of carbon. In addition, the data set provides location and descriptive information for each sample. Not all the descriptive fields contain information for a particular sample because it was not recorded by the submitter or because it was never entered into the database. No sample will contain analyses for all possible elements. The analytical methods used were selected by the sample submitter based on the goals of the individual project and will vary throughout the data set. The analytical methods, sample preparation protocols, and quality control protocols used for various sample media by the USGS are documented in the following publications:

  5. How consistent are the relationships among the observations, including topology?
    The NGDB rock data set was constructed by processing a subset of the original National Geochemical Database (NGDB), checking for errors where possible, and using various selection criteria. The following criteria were chosen for selecting data for the rock data set:

    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 analyte
    
    In 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.

How can someone get a copy of the data set?
