Description:
Abstract:
This dataset contains geochemical data for soil samples collected by U.S. Geological Survey (USGS) personnel and analyzed in the analytical laboratories of the Geologic Division of the USGS. These data represent analyses of soil samples collected in support of various USGS programs. The data were originally entered into the in-house Rock Analysis Storage System (RASS) database which was used by the Geologic Division from the early- 1970's through the late-1980's to archive geochemical data. An unpublished CD-ROM was developed in 1996 that contains the RASS data in GSSEARCH format. That CD was used to generate this data set.
Purpose:
These data may be useful for mineral resource evaluation and for defining geochemical baseline values and statistics.

Maintenance_and_Update_Frequency:
The RASS database is currently the focus of an error- identification and correction process that has, to this point in time (January 2001), concentrated on data from Alaska. Upgraded data files for Alaska from the RASS database are being placed on the following web site as they become available: http://pubs.usgs.gov/of/1999/of99-433/ The upgrades are primarly related to 1) additional information on the exact sample medium analyzed, 2) adding location coordinates where there were none, and 3) correcting location coordinates known to be inaccurate.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The samples in this dataset were chemically analyzed by a variety of techniques over a period of time from the early 1960's to the late 1980's. The accuracy of the data varies with the analytical methodology and with the concentration of the element being analyzed. 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 = 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.

B = the element was requested for analysis by the sample submitter, but for some reason the laboratories did not analyze for this element.

When appropriate, these qualifying values appear in this dataset as a separate field preceding each element. The attribute, or field name, for the qualifier field is always denoted by the letter "Q". For example, "N" in the "S_ASQ" field preceding an analytical data field labelled "S_AS" 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.
Logical_Consistency_Report:
The soil samples in this dataset were collected for a variety of purposes. Most of the studies were related to assessing the mineral resources of the study area. Not all samples were subject to the same sample preparation protocol or the same analytical protocol. For example, different size fractions of soil may have been analyzed for different study areas. One of the problems with the RASS database is that it did not have a mechanism for providing sample preparation protocol. In upgrading the RASS database, we will attempt to provide more detailed information where possible on how the samples were prepared prior to analysis.
Completeness_Report:
This dataset provides chemical data for Fe, Mg, Ca, Na, K, Ti, Mn, Ag, As, Au, B, Ba, Be, Bi, Cd, Co, Cr, Cu, La, Mo, Nb, Ni, Pb, Sb, Sc, Sn, Sr, U, V, W, Y, Zn, Zr, Th, Tl, F, Hg, Pt, and Pd. In addition, the dataset provides location and descriptive information for each sample. Not all the descriptive fields contain information for a particular sample because not all sample submitters completed all the fields. The analytical methods used were selected by the sample submitter based on the goals of the project and will vary throughout the data set. The predominant analytical methods used for samples in this dataset are:

Emission Spectrography: Grimes and Marranzino, 1968; Fe, Mg, Ca, Ti, Mn, Ag, As, Au, B, Ba, Be, Bi, Cd, Co, Cr, Cu, La, Mo, Nb, Ni, Pb, Sb, Sc, Sn, Sr, V, W, Y, Zn, Zr, Th, Ga, Ge, Pd, and Pt.

Atomic Absorption, partial extraction: O'Leary and Meier, 1986; O' Leary and Viets, 1986; Viets, 1978; Viets, Clark, and Campbell, 1984; Viets, O'Leary, and Clark, 1984; Ward and others, 1969: Ag, Bi, Cd, Cu, Mo, Pb, Sb, and Zn.

Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Sample locations were determined from USGS topographic maps of various scales. The accuracy is dependant on the scale of the map from which the determination was made as well as the care taken by the individual who made the determination. Unfortunately, some location coordinates were not carefully determined. In other cases, the individual who collected the samples only identified the location as a corner of the quadrangle in which the samples were collected. 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. The base maps, from which latitude and longitude coordinates were determined, use the 1927 North American Datum (NAD27) based on the Clarke 1866 ellipsoid.

Process_Step:
Process_Description:
The data were generated by the analytical laboratories of the U.S. Geological Survey over several years, beginning in the early 1960s and ending about 1987. Upon completion of the chemical analysis, the data were stored in the RASS database. An unpublished CD-ROM was developed in 1996 that contains the RASS data in GSSEARCH format. This CD-ROM was used to generated the data set in .dbf format. The RASS DBF file was imported into ArcView 3.2 and an ArcView shapefile was generated which contained 30974 sample locations (93 samples were eliminated due to location discrepancies).
