The 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. 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 PLUTO 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 deter-mination of coordinates from field sheets was a time consuming and error prone process. In order to facilitate the analysis of samples, a deci-sion was made to allow submitters to enter the coordinates for the lower left (SW) corner of the submitter's working field map on which the samples could be plotted, which was most commonly a 7.5' or 15' quad- rangle 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. There-fore, 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) Earth Ellipsoid or Datum: Since most of the coordinate data in the PLUTO database were determined from published USGS maps and not from recent GPS systems, the coordinates are based on the 1927 North American datum (also known as the Clarke 1866 ellipsoid). Most modern GPS sys-tems use the 1983 North American datum (NAD 83) or the World Geodetic System (WGS 84). If the PLUTO data are plotted using the wrong ellip-soid or datum, the location may be offset by a distance up to a couple hundred feet. 3) Geocoding: The submission of 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 database. Therefore the PLUTO database contains some incorrect and invalid codes. 4) One geocode, the Material Code was required. The Material Code designates the type of sample media analyzed. Unfortunately, there was no specific material code for "Heavy- Mineral-Concentrate" samples prior to 1991. Most, but not all, concentrate samples submitted since 1991 have a Material Code of K. Before 1991, most concentrate samples were coded as A (rock), D (unconsolidated sediment), or Z (other) based upon the parent material. The most common problem is in distinguishing pre-1991 stream sediments from heavy-mineral concentrates. The user should check the geocoding field for indication that the sample was "processed". Many times concentrate samples can also be determined from the contents of the description field. Additionally, the field number for a concentrate sample will commonly have a suffix of C, C1, C2, C3, H, HM, or HN. 5) The PLUTO database contains a considerable amount of data for coal samples, although there is no specific material code for coal. The material code for all coal samples in the database is I (Organic fuel or related substance). The description field is the most useful secondary field for identifying coal samples in the database. The analytical data on coal samples includes data on both whole coal and coal ash. Coal ash data is indexed in the database with "/A" following the element symbol (for example SiO2/A is silicon dioxide in ash). The ash data can be converted to a whole coal basis using the tabulated ash value (percent of sample remaining after combustion). We have observed that a large amount of the data for coal ash in the database (particularly spectroscopic data) has been entered as if the data were on the whole coal (i.e. without the "/A" designation on the index). 6) Qualifiers: Many analytical data values in the PLUTO database are accompanied by a qualifier - N, L, G, H, B which for compatibility with the GSBUILD/GSSEARCH software has been converted to numeric representa-tions: N = 1; L = 2; G = 3; H = 4; B = 5. The qualifiers are defined as follows: >N = Concentration was looked for but not detected at tabulated value >L or < = Concentration is less than the tabulated value >G or > = Concentration is greater than the tabulated value >H = The concentration could not be precisely determined because of interferences >B = Concentration was not determined The distinction between a value qualified by an N or an L is small and was not applied consistently between different types- of-analysis. For some semi-quantitative spectrographic methods, an N was used when an element concentration could not be detected and an L was used when the element could be detected but the concentration was below determination limits that could confidently be reported. In other words, a value qualified with an L was slightly more significant than one qualified with an N. However for other analytical methods, a concentration below the determination limits of the method may be qualified with either an N or an L depending upon the method, the analyst, or the laboratory. Therefore without specific knowledge of these factors, the safest way to treat values qualified with an N or an L is as "less than the tabulated value". 7) The data in the PLUTO CD-ROM database was entered manually by the analyst, or electronically via automatic data transfer from laboratory instruments. We have occasionally observed data in the database where we suspect there have been errors in data entry, or data tranmission (i.e. major element analyses that sum to greater than 1 gram/gram, or trace element analyses with unlikely exponents). It has not been possible to do a complete quality control check on the entire database. Therefore we encourage all users of the database to check the data with a critical eye. Are the analytical data geochemically consistent with the sample description as provided by the "geocoding"? Logical_Consistency_Report: The PLUTO CD-ROM database was constructed by processing the original PLUTO data base, checking for errors where possible, and using various selection criteria. The following criteria were chosen for selecting data for the CD-ROM PLUTO database: >Each sample must have a valid lab number (one character + 7 digits) >Each sample must have a valid state/location code. >Each sample must have a valid material code. >Each sample must have a valid latitude and longitude. >Each sample must be from the U.S. (including Alaska and Hawaii). >Each sample must contain valid analytical data. All data that have Latitude and Longitude values that fall within the boundaries of Indian reservations have also been deleted from the CD-ROM database, except for the Goshute and Wind River reservations. The deleted data is considered proprietary information by the corresponding reservations, and has not been approved for release. In the original PLUTO database the element fields are identified by numerical identification codes ("NIDS") which are defined by chemical species, units of concentration, and, in come cases, by analytical technique. "NIDS" in the PLUTO database are not preserved in the CD-ROM data base. All "NIDS" are converted either to the corresponding oxide (for major/minor elements) or to the element symbol (for minor or trace elements). (Data for multiple oxidation states are retained: e.g. Cr, CrO3, Cr2O3, Mn, MnO, MnO2, Mn203, FeO, Fe2O3, FeTO3.) The latitude and longitude are checked to see if they fall within the state and county specified. If the latitude and longitude fall outside the listed state and county, the distance in km of the tabulated lat. and long. from the specified county is reported in a separate field. Duplicate analytical results are deleted if the Type-of-analysis (TOA) codes are the same or if one or the other TOA code is missing. All missing data values have been deleted. Completeness_Report: Some data are not included in the CD-ROM data files. The database is mainly restricted to inorganic species as measured in whole rock samples. Most of the excluded data are specialized analyses (e.g. partial extraction data, water analyses, INAA coefficients of variation, etc.) Units (as defined by the "NIDS" in the PLUTO database) are not preserved in the CD-ROM data base. All data are reported in units of grams of analyte per gram of sample. Many samples in the PLUTO data set are missing the county code. If the county code is missing (or invalid), it is defined based on the latitude and longitude values, providing the state code is consistent with the latitude and longitude values. If the county code is present it must be valid for the specified state.
