    Description:
      Abstract: Mineral-resources personnel from the Alaska Division of Geological & Geophysical Surveys conducted reconnaissance sampling of the William Henry Bay area in the Juneau C-4 and D-4 quadrangles, August 9-13, 2011. This sampling project was part of a statewide assessment of Alaska's potential for rare-earth element mineralization. During the William Henry Bay field project 46 rock, sediment, and heavy-mineral concentrate samples were collected for geochemical analysis (geochemical, major oxide, minor oxide, trace element, and rare earth elements).
      Purpose: Fieldwork was performed to evaluate the mineral-resource potential of a block of State land near the mouth of William Henry Creek, and to investigate reported rare-earth-element, uranium, and thorium mineral occurrences on adjacent Tongass National Forest land. This fieldwork and sampling was conducted as part of the State's Rare Earth Element and Strategic Minerals Assessment project, which is designed to evaluate Alaska's potential for these resources.

    Attribute_Accuracy:
      Attribute_Accuracy_Report: All geochemical, major-oxide, minor-oxide, trace-element, and rare-earth-element analyses were conducted by Actlabs. Analytical methods and detection limits are listed in attribute definitions. In addition to the internal quality-control program at Actlabs, DGGS monitored analysis quality by inserting igneous-rock and REE standards of known composition into the sample roster for every sample batch.
    Logical_Consistency_Report: not applicable
    Completeness_Report: This dataset contains all of the analysis for major-oxide, minor-oxide, trace-element, and rare-earth-element geochemistry complete at the time of publication for all samples collected in the William Henry Bay area during August 2011.
    Positional_Accuracy:
      Horizontal_Positional_Accuracy:
        Horizontal_Positional_Accuracy_Report: Location data were downloaded from Garmin eTrex Legend HCx GPS units into a Microsoft 2007 Access database.
        Quantitative_Horizontal_Positional_Accuracy_Assessment:
          Horizontal_Positional_Accuracy_Value: 3
          Horizontal_Positional_Accuracy_Explanation: A value of estimated position error in meters was calculated by Garmin eTrex Legend HCx GPS units and recorded for each sample location. Estimated position error calculated by Garmin eTrex Legend HCx units had a minimum of 1 meter, a maximum of 9 meters, and an average of approximately 3 meters. The GPS system suffers from calculation and geometric error such as error in satellite positions, mathematical error introduced by the GPS formulas used to calculate position, and errors caused by narrow satellite alignments. Estimated position error is a value determined by the GPS manufacturer for the calculation and geometric error as a whole. 'Selective availability,' a deliberate degradation of GPS data managed by the U.S. government, was not operating during the time period these samples were collected.

      Process_Step:
        Process_Description: Fieldwork - Rock, stream sediment, and heavy-mineral pan-concentrate samples were collected from outcrops, float fields, and stream beds in the William Henry Bay area. Rock samples were chosen and collected on the basis of potential for mineralization (as identified by visual inspection). Igneous rocks as well as rocks that exhibited veining or alteration were preferentially chosen for geochemical examination. Heavy mineral concentrates were isolated by hand-panning in the field.
        Process_Date: 201108
      Process_Step:
        Process_Description: Sample Prep - All sample preparation for analysis was performed by Actlabs. Rocks intended for whole-rock analysis by Actlabs and those with a weathering rind were trimmed at DGGS with a tile saw prior to sample preparation at the laboratory. Rock samples were crushed to minus-10 mesh (1.7mm), mechanically split by riffling, and then pulverized to 95% minus-150 mesh (105 microns). A mild steel mill was used for pulverizing to minimize contamination of samples. Stream sediment and pan concentrate samples were dried at a temperature of 60C and then sieved to minus 80 mesh (177 microns). For Code-8 REE analysis, both rock and sediment samples were further pulverized to minus-200 mesh (0.074mm) using a mild-steel mill. Cleaning sand was used after every sample preparation to prevent contamination.
        Process_Date: 201110
      Process_Step:
        Process_Description: Sample Analysis - All samples were analyzed for major oxides, minor oxides and petrologic trace elements, as well as ore-related trace elements and rare earth elements. In addition to the internal quality-control program at Actlabs, DGGS monitored analysis quality by inserting igneous-rock and REE standards of known composition into the sample roster for every sample batch. The major oxide, minor oxide, petrographic trace-element, and ore-related trace-element analyses were conducted using inductively-coupled plasma (ICP) and inductively-coupled plasma mass spectrometry (ICP-MS) following lithium metaborate/tetraborate fusion. Mass balance was used for the major-oxide and minor-oxide analyses as an additional quality control technique, requiring elemental totals of oxides to be between 98 and 101 percent. Gold assays were performed using gravimetric analysis following fire assay (FA-GRAV) on 29.16 grams of material. Separate splits of 4 samples were reanalyzed for gold using Instrumental Neutron Activation Analysis following fire assay (FA-INAA); grams of material analyzed is noted in the .csv file. Detection limits for each of the reported oxide and elemental values obtained by the various methods are documented in the metadata file.
