  Description:

    Abstract:

      This dataset contains geochemical data for Alaska produced by the analytical laboratories of the Geologic Division of the U.S. Geological Survey (USGS).  These data represent analyses of stream-sediment, heavy-mineral-concentrate (derived from stream sediment), soil, and organic material samples.

      Most of the data comes from mineral resource investigations conducted in the Alaska Mineral Resource Assessment Program (AMRAP).  However, some of the data were produced in support of other USGS programs.  The data were originally entered into the in-house Rock Analysis Storage System (RASS) database.  The RASS database, which contains over 580,000 data records, was used by the Geologic Division from the early 1970's through the late 1980's to archive geochemical data.  Much of the data have been previously published in paper copy USGS Open-File Reports by the submitter or the analyst but some of the data have never been published.



      Over the years, USGS scientists recognized several problems with the database.  The two primary issues were location coordinates (either incorrect or lacking) and sample media (not precisely identified).  This dataset represents a re-processing of the original RASS data to make the data accessible in digital format and more user friendly.  This re-processing consisted of checking the information on sample media and location against the original sample submittal forms, the original analytical reports, and published reports.  As necessary, fields were added to the original data to more fully describe the sample preparation methods used and sample medium analyzed.  The actual analytical data were not checked in great detail, but obvious errors were corrected.

    Purpose: These data may be useful both in exploring for mineral deposits and in establishing regional geochemical baseline information for the various sample media analyzed.

    Attribute_Accuracy_Report:

      The samples in this dataset were chemically analyzed by a variety of techniques over a period of time from the mid-1960's to the late 1980's.  For some elements, the methods of chemical analysis were the same throughout the study, while for others, the methods changed as analytical technology improved.  The accuracy of the data varies with the analytical methodology and with the concentration of the element being analyzed.

      A qualifier such as N, L, G, H, and B accompanies some analytical data values.  These qualifiers are defined as follows:



      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 often given in the accompanying data field



      L = the element was detected by the technique but at a level below the lowest reportable lower limit of determination for the method.  The value is of the lower limit of determination is often given in the accompanying data field



      G = the element was measured at a concentration greater than the upper limit of determination for the method



      H = an analytical value could not be determined due to physical, chemical, or spectral interference



      B = an analytical value was not determined



      These qualifying values appear in this dataset as a separate field preceding each element.  The attribute, or field name, for the qualifying values field always ends with a Q.  For example S_FE_Q would be the name of the field containing and N, L, G, H, or B qualifiers for iron analyzed by optical emission spectroscopy.

  Logical_Consistency_Report: For some elements, the methods of chemical analysis were the same throughout the study, while for others, the methods changed as analytical technology improved.  Some of the methods used were specifically designed to give a concentration value based on a partial digestion or extraction of the sample.  For these methods elements tightly bound in the structure of silicates in the sample are not measured.  Therefore, the analytical results from these partial extraction techniques may not be comparable with results from methods designed to measure the total concentration of an element in a sample.

  Completeness_Report:

    This dataset provides information on up to 30 descriptive fields for each sample.  Not all the descriptive fields contain a value for a particular sample either because it was not recorded by the submitter or not appropriate for the sample media.  The samples were analyzed by a variety of methods resulting in up to 170 data fields.  Not all samples were analyzed by every single method.  Analytical methods were generally selected by the submitter based on the sample media and the goals of the project.  The predominant analytical methods used for samples in this dataset are:

    Sample Preparation Methods:



    Various sample preparation methods were used depending on the sample media.  Stream-sediment and soil samples were generally sieved to minus-80 mesh before pulverizing but other sieve sizes may have been used depending on the requirements of the submitter and the nature of investigation for which the samples were collected.  Heavy-mineral-concentrate samples were usually sieved to minus-35 mesh prior to further separation but again other sieve sizes may have been used.  Most of the heavy-mineral-concentrate samples were panned in the field and subjected to heavy liquid and magnetic separation in the laboratory prior to analysis.  However there are some samples that were only panned in the field and then analyzed in the laboratory.  Occasionally there are heavy-mineral-concentrate samples that were field panned, subjected to heavy liquid and magnetic separation, and then 2 or more of the magnetic separation fractions were combined for analysis.  Each sample in the database has been coded in the DESCRIPT1, DESCRIPT2, and MESH_SIZE fields to describe the sample media and preparation methods used as accurately as possible.  Sample preparation methods used and references are given below:



    Stream-sediment and soil samples are thoroughly dried, generally at less than 50 degrees C.  The dried samples are disaggregated by hand as necessary and as much organic material as possible is removed.  The samples are then sieved to the required particle size using stainless steel sieves.  The sieved fraction is generally ground using a vertical pulverizer with ceramic plates, placed in a 3-ounce cardboard sample container, and mixed to ensure homogeneity.



    Heavy-mineral-concentrate samples are generally sieved through a minus-10 mesh (2 mm) screen into a 14-16 inch stainless-steel gold pan and then further reduced by panning.  In the laboratory, the remaining sample is sieved through a minus-35 mesh screen.  The minus-35 mesh fraction is separated into heavy and light fractions using bromoform with a specific gravity of 2.8.  The heavy fraction, the sample material with specific gravity >2.8, is further separated magnetically using a Frantz Isodynamic Separator, into a highly magnetic (ferromagnetic, C1) fraction, a weakly magnetic (paramagnetic, C2) fraction, and a nonmagnetic  (C3) fraction.  Depending on the amount of material available, the heavy, nonmagnetic (C3) fraction is divided into an analytical split and a split used for mineralogical identification by the submitter.  The analytical split is pulverized using an agate mortar and pestle.

  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.  When submitters reported locations as degree, 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 latitude and longitude degrees, minutes, and seconds have been converted to decimal degrees for this dataset.  The base maps, from which latitude and longitude coordinates were determined, use the 1927 North American Datum (NAD27) based on the Clarke 1866 ellipsoid.

  Lineage:

    Process_Step:

      Process_Description: The data were generated by the analytical laboratories of the U.S. Geological Survey over several years, beginning about 1966 and ending about 1987.  Upon completion of the sampling and analysis, the data were keypunched and stored in the Rock Analysis Storage System (RASS) database.  In 1998 re-processing of the database was initiated to correct errors in sample locations, to add sample locations when missing, and to correctly identify the sample media of each record.  This was done by checking the information on the original sample submittal forms, the original analytical reports, and published reports, and discussions with submitters.  New fields have been added to the database to more accurately describe sample media and sample preparation methods used.  Analytical data fields were changed to include the reporting units.
