    Description:
      Abstract:
        This report presents geochemical analyses for 220 mostly altered and
        mineralized rock samples from the Red Dog Zn-Pb-Ag district in the
        western Brooks Range of northern Alaska. These data form the basis
        for a study by Slack et al. (2004a) on hydrothermal silicification
        and related alteration in wall rocks of the Red Dog deposits and the
        Anarraaq deposit 10 km to the northwest. The sulfide deposits occur
        within the Ikalukrok unit (informal name) of the Mississippian Kuna
        Formation (Moore and others, 1986). Principal rock types that were
        analyzed include black and gray shale, unmineralized bedded barite,
        mineralized (sulfide-rich) bedded barite, sulfide-rich silica rock
        (replaced barite), massive and semimassive sulfide, vein chalcedony,
        and Brookian (Cretaceous) vein quartz. For stratigraphic
        completeness, data are also reported here for a limited number of
        unaltered and unmineralized samples of black and gray shale,
        laminated carbonate-rich shale, lithic turbidite, bedded siliceous
        rock, calcareous radiolarite, and tectonic mlange. Detailed
        descriptions of the sampled sulfide deposits and their stratigraphic
        settings are given in Slack and others (2004a) and Kelley and
        others (2004a, b). The geochemical analyses are presented here in
        Microsoft Excel and .dbf spreadsheet formats in order to facilitate
        calculations and plotting of data. A related geochemical database on
        unaltered Paleozoic sedimentary rocks of the western Brooks Range is
        available in Slack and others (2004b).
      Purpose:
        These data form the basis for a study by Slack et al. (2004a) on
        hydrothermal silicification and related alteration in wall rocks of
        the Red Dog deposits and the Anarraaq deposit 10 km to the
        northwest.
      Supplemental_Information:
        Data for elements, oxides, and other components are presented either
        in weight percent or parts per million, except for Au that are in
        parts per billion. Qualified values (shown by the '<' symbol)
        represent values less than the specified minimum detection limit
        (MDL).  In some cases, the MDL for a particular element or
        component is not uniform, which reflects changing analytical
        conditions or matrix effects, or use of newer ICP-MS instruments
        that have higher precision and lower MDLs.  For statistical
        treatment of data and other calculations, it is recommended that
        qualified values be substituted by one-half the analytical
        detection limit (Sanford and others, 1993). Note that the
        abbreviation "n.a." refers to a lack of analysis for the specified
        element or component.

        Values for the magnitude of the Ce and Eu anomalies are also
        presented. The magnitude of the Ce anomaly, Ce/Ce*, is calculated as:
        Ce[CN]/((La[CN])**0.667 * (Nd[CN])**0.333)
        where Ce[CN], La[CN], and Nd[CN] represent normalization of
        Ce, La, and Nd respectively to average chondrites using the
        data of Nakamura (1974). The magnitude of the Eu anomaly,
        Eu/Eu*, is calculated as:
        Eu[CN]/(Sm[CN]*Gd[CN])**0.5
        with chondrite normalization of Eu, Sm, and Gd represented
        respectively as Eu[CN], Sm[CN], and Gd[CN].
        In these formulae, two asterisks (**) are used to represent
        exponentiation; one alone indicates multiplication.

    Attribute_Accuracy:
      Attribute_Accuracy_Report:
        Precision and accuracy for concentrations 100x the minimum detection
        limit (MDL) was generally better than 5 % relative, and in many
        cases such as for major elements was better than 1 % relative.
        For concentrations approximately 10x the MDL, precision and accuracy
        were about 10-20 % relative depending on the method used.
    Logical_Consistency_Report:
      Multiple standards were analyzed together with the submitted rock
      samples.  Analyses by ACT Labs included data on 8 to 10
      compositionally different standards with well-defined elemental
      concentrations.  In addition to these standards, analyses were
      routinely obtained on duplicate samples and Ohio black shale SDO-1
      (http://minerals.cr.usgs.gov/geochem/ohioshale.html).
    Completeness_Report:
      Data are available for most elements in most samples.  The
      code "n.a." is used to indicate an unavailable analysis;
      it occurs in only nine fields:

        Process_Description:
          Geochemical analyses were obtained mostly on samples of diamond
          drill core 3.5 or 4.5 cm in diameter. Several analyzed samples
          come from mine faces within the Red Dog open pit (Main deposit) or
          from outcrops in the region.  Samples were cut using water-cooled
          diamond saws in order to remove oxidized or weathered surfaces.
          Particular care was taken to cut out visible veins from altered
          wall rocks so that each analysis would represent a single rock
          type.  Note, however, that disseminated and laminated sulfides
          (e.g., pyrite laminae in black shale) were retained in the samples
          prior to analysis.  All samples were pulverized in an alumina
          ceramic mortar, which in some cases may have produced very minor
          contamination by trace amounts of Al, Ba, or rare earth elements
          (REE).

          Prior to analysis all samples were fused with lithium metaborate/
          tetraborate to insure nearly complete acid digestion of resistate
          minerals such as zircon, monazite, rutile, chromite, and barite.
          All samples were analyzed by Activation Laboratories (ACT Labs) in
          Ancaster, Ontario, using methods described on their web site:
          <http://www.actlabs.com/>.  Major elements, most trace elements,
          and REE were determined by inductively-coupled plasma mass
          spectrometry (ICP-MS), using an approach similar to that of Jenner
          and others (1990).  REE in some barite samples were analyzed by
          high-resolution, magnetic sector ICP-MS using an ion exchange
          technique in order to eliminate Ba interference on Eu.  Volatiles
          and related components (total C, CO2, Corg, S, SO4) were
          determined using conventional methods as described in Jackson and
          others (1987).  Fluorine was analyzed by the ion selective
          electrode technique (Jackson and others, 1987).  Data for Sc, Cr,
          Co, Au, Sb, As, and Se in most samples were obtained by
          instrumental neutron activation analysis (Hoffman, 1992), which
          provides more precise results than by ICP-MS.  Au concentrations in
          most samples of semimassive and massive sulfide were also obtained
          by flame atomic absorption (Aruscavage and Crock, 1987) by XRAL
          Laboratories of Denver, CO, using on splits of the same rock
          powders that were earlier run for major and trace elements, and
          REE.

          Multiple standards were analyzed together with the submitted rock
          samples.  Analyses by ACT Labs included data on 8 to 10
          compositionally different standards with well-defined elemental
          concentrations.  In addition to these standards, analyses were
          routinely obtained on duplicate samples and Ohio black shale SDO-1
          (http://minerals.cr.usgs.gov/geochem/ohioshale.html).  Precision
          and accuracy for concentrations 100x the minimum detection limit
          (MDL) was generally better than 5 % relative, and in many cases
          such as for major elements was better than 1 % relative.  For
          concentrations approximately 10x the MDL, precision and accuracy
          were about 10-20 % relative depending on the method used.
