The objectives of DGGS's resource assessment are to improve the trace-element geochemical coverage of selected watersheds; to obtain modern, quantitative geochemical analyses; to understand the petrogenesis of the granites; and to better document established mineral occurrences. Stream-sediment, pan-concentrate, and rock sampling were conducted as part of the State's Rare Earth Elements and Strategic Minerals Assessment project, which is designed to evaluate Alaska's potential for these resources. Highlights of this sampling project include documenting patterns of variable REE enrichment in the granites, and identifying bedrock samples of greisen and oxidized breccias with enriched REE, and stream sediments with enriched REEs that have a pattern of variation that mimics that of the granites.\nThe objectives of DGGS's resource assessment are to improve the trace-element geochemical coverage of selected watersheds; to obtain modern, quantitative geochemical analyses; to understand the petrogenesis of the granites; and to better document established mineral occurrences. Stream-sediment, pan-concentrate, and rock sampling were conducted as part of the State's Rare Earth Elements and Strategic Minerals Assessment project, which is designed to evaluate Alaska's potential for these resources.\nThis data distribution package consists of multiple CSV files which provide sample locations and descriptions, geochemical data, analytical methods, and instrumentation detection limits for analysis of the samples collected for this project. For each analytical data type, a primary table presents the analytical results, sample locations, and other information about each sample. A secondary table provides detailed information about the methods and detection limits of the instrumentation used to analyze the data. The DGGS metadata standard extends the FGDC standard to include elements that are required to facilitate our internal data management. These elements, referred to as \"layers,\" group and describe files that have intrinsic logical or topological relationships. Attribute information for each layer is included in this metadata file under the \"Entity_and_Attribute_Information\" section. The metadata layer provides the metadata, codesets, or other documentation files applicable to all layers.

Some samples were retested for quality control purposes and the results were not included in the publication because the variance of the samples had a mean of 1.25 percent and presented no significant change. We report measured values which are above and/or below instrument detection limits when they are provided to us by the originating lab. These cases are noted within the detection limits tables. Users should contact the originating labs for additional information about detection limits and reporting procedures. For high-grade and mineralized rare earth samples, high sample to volume ratios are utilized in the Inductively Coupled Plasma - Atomic Emission Spectroscopy analysis to improve precision. Certified high grade rare earth reference materials are used as part of the standard protocol. These cases are noted in the detection limits tables.\n\nnot applicable\nAll of the samples collected were analyzed by methods appropriate to the sample media. This publication also includes location coordinates of potential sample sites in which samples were not collected for reasons noted.\n\n\nLocation data were collected using Trimble TSC3 WAAS-enabled GPS devices running ArcPad 10. Data were downloaded directly from the ArcPad .AXF file into a field geodatabase set up in ArcMap. WAAS-enabled GPS devices have a reported error of about 1 meter. Sample points that were placed in the database without GPS have an estimated error ranging from 20 to 170 meters. Latitude and longitude were calculated from the GPS's UTM zone values in ArcMap using the 'calculate geometry' function and are reported using the NAD 27 datum.\n\n\n\n\n\n\nBarker, J.C.\n1992\nInvestigation of tin-rare earth element placers in the Ray River watershed\n\nOpen-File Report\nOFR 34-91\n\n\nUnited States\nU.S. Bureau of Mines\n\n63 p., 1 sheet, scale 1:63,360\nhttp://www.dggs.alaska.gov/pubs/id/21385\n\n\n63360\npaper\n\n\n\n1992\n\n\npublication date\n\nBarker, J.C., 1992\nPreliminary research and fieldwork\n\n\n\n\nBarker, J.C.\nFoley, J.Y.\n1986\nTin reconnaissance of the Kanuti and Hodzana Rivers uplands, central Alaska\n\nInformation Circular\nIC 9104\n\n\nUnited States\nU.S. Bureau of Mines\n\n27 p\nhttp://www.dggs.alaska.gov/pubs/id/21287\n\n\npaper\n\n\n\n1986\n\n\npublication date\n\nBarker, J.C. and Foley, J.Y., 1986\nPreliminary research and fieldwork\n\n\n\n\nFoley, J.Y.\nMcDermott, M.M.\n1983\nPodiform chromite occurrences in the Caribou Mountain and lower Kanuti River areas, central Alaska, part I: reconnaissance investigations\n\nInformation Circular\nIC 8915\n\n\nUnited States\nU.S. Bureau of Mines\n\n8 p., 1 sheet\nhttp://www.dggs.alaska.gov/pubs/id/21279\n\n\npaper\n\n\n\n1983\n\n\npublication date\n\nFoley, J.Y. and McDermott, M.M., 1983\nPreliminary research and fieldwork\n\n\n\n\nSmith, S.M.\n1997\nNational geochemical database - Reformatted data from the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) Program\n\nOpen-File Report\nOF 97-492\n\n\nUnited States\nU.S. Geological Survey\n\nhttp://www.dggs.alaska.gov/pubs/id/25462\n\n\ndigital data\n\n\n\n1997\n\n\npublication date\n\nSmith, S.M., 1997\nPreliminary research and fieldwork\n\n\nPreliminary research and fieldwork - Mineral-resources personnel from the Alaska Division of Geological & Geophysical Surveys (DGGS) carried out a helicopter-supported geological and geochemical resource assessment project in the Beaver, Bettles, Livengood, and Tanana quadrangles from June 23 through August 5, 2012. This location was targeted based on previously published datasets and reports which documented concentrations of base metals, tin, tungsten, chromium, rare-earth elements (REEs), and uranium in the project area. Fieldwork consisted of stream-sediment, pan-concentrate, and rock sampling.\nBarker, J.C., 1992\nBarker, J.C. and Foley, J.Y., 1986\nFoley, J.Y. and McDermott, M.M., 1983\nSmith, S.M., 1997\n2012\n\n\nTrace-element and rare-earth-element analysis of pan-concentrate samples - Pan-concentrate samples were dried at DGGS using a hot plate and glass petri dishes, which were washed after each use to prevent cross-contamination. Dried samples were weighed to the nearest 0.1 gram and then split manually into two equal-sized, homogeneous portions using a Sepor(TM) micro splitter, which was washed after each use. One split was retained by DGGS for mineralogical studies, the other split was submitted to ALS Minerals (formerly ALS Chemex), and underwent the PREP-31 package, where the sample was logged, dried, weighed, and the entire sample was pulverized to a nominal 85% passing 75 microns (-180 mesh). Samples were analyzed for trace elements and rare earth elements using: Inductively Coupled Plasma - Atomic Emission Spectroscopy (HF-HNO3-HClO4-HCl digestion), Inductively Coupled Plasma - Mass Spectroscopy (Lithium metaborate fusion - HNO3-HCl dissolution), and/or Inductively Coupled Plasma - Atomic Emission Spectroscopy (Fire assay - aqua regia digestion). The method used to analyze each element is listed in the detection limits table. For high-grade and mineralized rare earth samples, high sample to volume ratios are utilized in the Inductively Coupled Plasma - Atomic Emission Spectroscopy analysis to improve precision. Certified high grade rare earth reference materials are used as part of the standard protocol. See ALS documentation for a more detailed discussion of the methodology.\n2012\n\n\nMajor- and minor-oxide, trace-element, and rare-earth-element analysis of pulverized rock samples - Igneous and meta-igneous rocks showing little alteration or weathering were collected for major-oxide, minor-oxide, and trace-element analyses to determine bulk rock composition of igneous and meta-igneous lithologies, or to identify the tectonic setting of a sample's protolith from petrogenetically important trace elements. These samples were prepared by ALS Minerals in accordance with their PREP-31 package which involves crushing the entire sample to less than 70 percent passing -10 mesh (2 mm), then splitting off 250 grams and pulverizing the split to better than 85 percent passing 75 microns. Samples were analyzed using: X-Ray Fluorescence (Lithium Borate Fusion), and/or Inductively Coupled Plasma - Mass Spectroscopy (Lithium metaborate fusion - HNO3-HCl dissolution). See ALS documentation for a more detailed discussion of the methodology.\n2012\n\n\nTrace-element and rare-earth-element analysis of pulverized rock samples - Rock samples of visibly mineralized rock, or rocks exhibiting features associated with mineralization, were preferentially collected and analyzed for geochemical trace elements and rare earth elements. These samples were prepared by ALS Minerals in accordance with their PREP-31 package which involves crushing the entire sample to less than 70 percent passing -10 mesh (2 mm), then splitting off 250 grams and pulverizing the split to better than 85 percent passing 75 microns. Samples were analyzed for trace elements and rare earth elements using: Inductively Coupled Plasma - Mass Spectroscopy (Lithium metaborate fusion - HNO3-HCl dissolution), X-Ray Fluorescence (Lithium Borate Fusion), Inductively Coupled Plasma - Atomic Emission Spectroscopy (Fire assay - aqua regia digestion), Inductively Coupled Plasma - Atomic Emission Spectroscopy (HF-HNO3-HClO4-HCl digestion), and/or Inductively Coupled Plasma - Atomic Emission Spectroscopy (HNO3-HClO4-HF+HCl digestion). See ALS documentation for a more detailed discussion of the methodology.\n2012\n\n\nMajor- and minor-oxide and trace-element analysis of rock-slab samples - Fine-grained igneous and meta-igneous rocks showing little alteration or weathering were collected for major-oxide, minor-oxide, and trace-element petrographic analysis using \"slab\" X-ray fluorescence (slab XRF) in order to determine bulk rock composition of igneous and meta-igneous lithologies, or to identify the tectonic setting of a sample's protolith from petrogenetically important trace elements. See report manuscript for a more detailed discussion of the methodology.\n2012\n\n\nTrace-element and rare-earth-element analysis of stream-sediment and soil samples - Stream-sediment sample locations were selected prior to fieldwork to fulfill two different needs: (1) to fill data gaps between previously collected samples with known anomalous values for REE and related elements; and (2) to fill gaps between previously collected samples. Priority was given to samples in closer proximity to the Dalton Highway Trans-Alaska Pipeline System corridor and to samples in drainage basins in or near the mapped extent of granitic plutons. In the field, specific sample locations were selected by visual inspection from the helicopter, and were based on the availability of sample material and a suitable landing zone. Specific sites along streams/rivers at the sample location were then selected, in order of preference from highest to lowest, as follows: gravel/cobble-armored riffles, gravel/cobble-armored point bars, log/boulder/plunge-pool eddies, point bars, overbank flood deposits, and moss mats. Stream-sediment samples were collected with a shovel. Cobbles and larger pebbles were manually screened out by hand, and the remaining material was placed into a permeable cloth sample bag and air dried at camp. To ensure a sufficient volume of fine sediment, 7-inch-wide by 12-inch-long sample bags were filled to capacity. Stream-sediment samples were air dried by DGGS, and then submitted to ALS Minerals (formerly ALS Chemex), and underwent the PREP-41 package, where the sediment were logged, air-dried at low temperature, and weighed. The samples were then sieved to a particle size of -180 microns (-80 mesh). Both fractions were retained, and the -80-mesh fraction was crushed and used for analysis. Some samples lacking sufficient fine material were screened to -35-mesh prior to crushing. Samples were analyzed for trace elements and rare earth elements using: Inductively Coupled Plasma - Mass Spectroscopy (Lithium metaborate fusion - HNO3-HCl dissolution), Inductively Coupled Plasma - Atomic Emission Spectroscopy (Fire assay - aqua regia digestion), and/or Inductively Coupled Plasma - Atomic Emission Spectroscopy (HF-HNO3-HClO4-HCl digestion). See ALS documentation for a more detailed discussion of the methodology.\n2012\n\n\nList of visited locations in which samples were not collected for reasons noted - In some cases, targeted sample sites were found to be inaccessible or did not provide suitable sampling media.

For this project a unique station value was created for all visited sites that yielded samples. However, the \"Station\" identifier does not uniquely identify each sample; in some cases, multiple samples were collected from the same site for different purposes. In other cases, a station number may be duplicated because the lab provided multiple analyses for a particular sample.\nAlaska Division of Geological & Geophysical Surveys\n\nGeneric example of a station identifier: 20YYAAA9999X: YY=last two digits of year, AAA=geologist's initials (one to three characters), 9999=unique station number, X= optional alpha character which indicates that multiple samples were collected at a given location or that multiple observations were recorded in the project database. The initials used by the geologists who collected samples for this project are: AT = Amy L. Tuzzolino; BW = William (aka Bill) Wylie; LF = Larry Freeman; RN = Rainer Newberry; MJB = Michael J.

For this project a unique station value was created for all visited sites that yielded samples. However, the \"Station\" identifier does not uniquely identify each sample; in some cases, multiple samples were collected from the same site for different purposes. In other cases, a station number may be duplicated because the lab provided multiple analyses for a particular sample.\nAlaska Division of Geological & Geophysical Surveys\n\nGeneric example of a station identifier: 20YYAAA9999X: YY=last two digits of year, AAA=geologist's initials (one to three characters), 9999=unique station number, X= optional alpha character which indicates that multiple samples were collected at a given location or that multiple observations were recorded in the project database.

For this project a unique station value was created for all visited sites that yielded samples. However, the \"Station\" identifier does not uniquely identify each sample; in some cases, multiple samples were collected from the same site for different purposes. In other cases, a station number may be duplicated because the lab provided multiple analyses for a particular sample.\nAlaska Division of Geological & Geophysical Surveys\n\nGeneric example of a station identifier: 20YYAAA9999X: YY=last two digits of year, AAA=geologist's initials (one to three characters), 9999=unique station number, X= optional alpha character which indicates that multiple samples were collected at a given location or that multiple observations were recorded in the project database.

For this project a unique station value was created for all visited sites that yielded samples. However, the \"Station\" identifier does not uniquely identify each sample; in some cases, multiple samples were collected from the same site for different purposes. In other cases, a station number may be duplicated because the lab provided multiple analyses for a particular sample.\nAlaska Division of Geological & Geophysical Surveys\n\nGeneric example of a station identifier: 20YYAAA9999X: YY=last two digits of year, AAA=geologist's initials (one to three characters), 9999=unique station number, X= optional alpha character which indicates that multiple samples were collected at a given location or that multiple observations were recorded in the project database. The initials used by the geologists who collected samples for this project are: AT = Amy L. Tuzzolino; BW = William (aka Bill) Wylie; LF = Larry Freeman; RN = Rainer Newberry; MJB = Michael J. Blessington; MBW = Melanie B. Werdon; CW = T. Colby Wright; and EB = Erik N.
