Publication_Date: 2011 Title: Geochemical, major-oxide, minor-oxide, trace-element, carbon, and rare-earth-element data from rocks collected in 2011 in the Moran area, Tanana and Melozitna Quadrangles, Alaska Geospatial_Data_Presentation_Form: tabular digital data, report Series_Information: Series_Name: Raw Data File Issue_Identification: RDF 2011-4 v. 2 Publication_Information: Publication_Place: Fairbanks, AK, USA Publisher: State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys Other_Citation_Details: 118 pp. Online_Linkage: http://dx.doi.org/10.14509/23002 Description: Abstract: Mineral-resources personnel from the Alaska Division of Geological & Geophysical Surveys carried out a geologic field survey, including mapping and sampling in the Moran area in the Tanana A-6 and B-6 quadrangles, and the Melozitna A-1, A-2, B-1, and B-2 quadrangles, Alaska, from June 17 to August 15, 2011. The fieldwork provides basic information critical to building an understanding of Alaska’s geology and is part of an integrated program of airborne geophysical surveys followed by geologic mapping. During 2011, 212 rock samples were collected for geochemical trace-element analysis (tables 1–3), 58 rock samples were collected for whole-rock (major- and minor-oxide and petrogenetically important trace elements) analyses, two samples were collected for analysis of non-carbonate carbon content, 439 polished rock slabs were analyzed for whole rock and petrogenetically important trace elements, and 26 samples were analyzed for rare earth elements. Purpose: The analyses in this report were acquired as part of a geologic mapping program, the purpose of which is to provide 1:63,360-scale geologic mapping of the Moran airborne geophysical survey released by DGGS in 2010 (Burns et al., 2010). The geophysical survey (helicopter-based aeromagnetic and electromagnetic data) and geologic mapping are part of the Alaska Airborne Geophysical/Geological Mineral Inventory Program, a special multi-year investment by the State of Alaska to expand Alaska's geologic and mineral resources knowledge base, catalyze future private-sector mineral exploration and development, and guide state resource development planning. Supplemental_Information: The DGGS metadata standard extends the FGDC standard to also include several elements that are required to facilitate our internal data management. These elements (referred to as "layers") relate individual data items to a common dataset. The dataset is available in tabular format as comma delimited ascii files and organized into five layers, as described in this metadata file under the "Entity_and_Attribute_Information" section. The layers are as follows: >trace-element-geochemistry: sample locations and descriptions, geochemical data, analytical methods and detection limits >whole-rock-geochemistry: sample locations and descriptions, geochemical data, analytical methods and detection limits >non-carbonate-carbon-geochemistry: sample locations and descriptions, and geochemical data, analytical methods and detection limits >slab-xrf-geochemistry: sample locations and descriptions, geochemical data, analytical methods and detection limits >rare-earth-geochemistry: sample locations and descriptions, geochemical data, analytical methods and detection limits Time_Period_of_Content: Time_Period_Information: Range_of_Dates/Times: Beginning_Date: 20110617 Ending_Date: 20110815 Currentness_Reference: ground condition Status: Progress: Complete Maintenance_and_Update_Frequency: None planned Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -154.735482 East_Bounding_Coordinate: -152.471008 North_Bounding_Coordinate: 65.507439 South_Bounding_Coordinate: 65.107451 Keywords: Theme: Theme_Keyword_Thesaurus: ISO 19115 Topic Category Theme_Keyword: geoscientificInformation Theme: Theme_Keyword_Thesaurus: None Theme_Keyword: Geochemical Data Theme_Keyword: Geochemistry Theme_Keyword: Gold Theme_Keyword: Major Oxides Theme_Keyword: Minor Oxides Theme_Keyword: Platinum Group Elements Theme_Keyword: STATEMAP Project Theme_Keyword: Trace Elements Theme_Keyword: Trace Geochemical Theme_Keyword: Trace Metals Place: Place_Keyword_Thesaurus: None Place_Keyword: Alaska, State of Place_Keyword: Tanana Quadrangle Place_Keyword: Melozitna Quadrangle Place_Keyword: Moran Dome Place_Keyword: Moran Creek Place_Keyword: Yukon River Place_Keyword: Melozitna Mining District Place_Keyword: Kokrines Hills Place_Keyword: Grant Creek Place_Keyword: Little Melozitna Hot Springs Stratum: Stratum_Keyword_Thesaurus: None Stratum_Keyword: Ruby Terrane Temporal: Temporal_Keyword_Thesaurus: None Temporal_Keyword: Devonian Temporal_Keyword: Jurassic Temporal_Keyword: Cretaceous Temporal_Keyword: Paleozoic Temporal_Keyword: Proterozoic Access_Constraints: This dataset is available directly from the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (see contact information below).

Analytical methods and detection limits are listed in attribute definitions. This information is also described in the report text. In addition to ALS Chemex’s own internal quality control program, DGGS monitored analysis quality by inserting one sample of known composition into the sample roster for every 20-sample batch. For the trace-element geochemical analyses, the results of one DGGS-standard sample differs from its known composition by more than one standard deviation; all samples in this 20-sample batch are noted in the trace-element-geochemistry layer by a carat next to the Sample_ID, and mineralized samples were re-run for gold by FA-ICP-AES; repeat values of the standard are within acceptable range. Procedures used by the University of Alaska Fairbanks are routinely checked using well-characterized standards, which are described further in this metadata file under the "Lineage" portion of the 'Data_Quality_Information" section. Logical_Consistency_Report: No topologic relationships are present in data. Completeness_Report: This dataset contains all of the analyses for trace-element geochemistry, whole-rock (major- and minor-oxide, and trace-element) geochemistry, non-carbonate-carbon geochemistry, and rare-earth-element geochemistry analyses complete at the time of publication for rock samples collected in 2011 by DGGS in the Moran area project, but excludes rocks collected in 2011 by DGGS from core that Doyon Drilling, Inc. drilled in the Moran project area between 2007 and 2009. 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 with a minimum error of 1 meter, a maximum error of 9 meters, and an average error of 3 meters. 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. Lineage: Process_Step: Process_Description: Fieldwork for trace-element samples - Rock samples of visibly mineralized rock, or rock exhibiting features associated with mineralization, were preferentially collected and analyzed for geochemical trace elements. Spatially these rocks were collected randomly. Occasionally rocks exhibiting a specific feature were selectively collected and these instances were noted in the sample description. Process_Date: 2011 Process_Step: Process_Description: Fieldwork for whole-rock samples - Rock samples for whole-rock analyses at ALS Chemex (major-oxide, minor-oxide, and trace-element analyses) were collected to determine 1) bulk rock composition of igneous and meta-igneous lithologies, or 2) the tectonic setting of a sample’s protolith based on petrogenetically important trace elements. Unweathered or minimally weathered rock samples were preferentially selected for analysis. Process_Date: 2011 Process_Step: Process_Description: Fieldwork for non-carbonate-carbon samples - Rock samples of visibly carbonaceous or graphitic metamorphic rock were preferentially collected and analyzed for non-carbonate carbon content. Spatially these rocks were collected randomly. Unweathered or minimally weathered rock samples were preferentially selected for analysis. Process_Date: 2011 Process_Step: Process_Description: Fieldwork for slab-XRF samples - Rock samples for whole-rock analyses (major-oxide, minor-oxide, and trace element analyses) by XRF at UAF were collected to determine 1) bulk rock composition of igneous and meta-igneous lithologies, or 2) the tectonic setting of a sample’s protolith based on petrogenetically important trace elements. Samples for slab-XRF analysis typically had grain sizes less than 3mm. Spatially these rocks were collected randomly. Process_Date: 2011 Process_Step: Process_Description: Fieldwork for rare-earth-element samples - Plutonic and metamorphic samples for rare-earth-element analyses (major-oxide, minor-oxide, and trace element analyses) were selected from the samples analyzed for whole-rock geochemistry. These samples were selected based on sample quality (unweathered) and location (random distribution across study area). Process_Date: 2011 Process_Step: Process_Description: Trace-element sample preparation - Preparation for samples analyzed by ALS Chemex was conducted at the ALS Chemex sample preparation facility. Rock samples were crushed with a Terminator oscillating jaw crusher with chrome steel alloy plates so that at least 70 percent of the material passed through a -10 mesh (2 mm) screen. Representative aliquots of 250 grams each were taken using a stainless steel riffle splitter. These samples were then pulverized in an Essa ring mill bowl and pucks made of Essa’s Standard Steel alloy so that 85 percent of the sample passed through a -200 mesh (75 micron) screen. Trace-element analyses and non-carbonate-carbon analyses were performed using representative splits of each 250 gram pulp. Process_Date: 2011 Process_Step: Process_Description: Whole-rock sample preparation - Rocks with a weathering rind were trimmed at DGGS with a tile saw prior to sample preparation at the ALS laboratory where they were prepared using the same methods and equipment as the trace-element samples. Whole-rock analyses were performed using representative splits of the resulting 250g pulp. Process_Date: 2011 Process_Step: Process_Description: Non-carbonate-carbon sample preparation - Samples were prepared using the same methods and equipment as the trace-element samples; the Non-carbonate-carbon analyses were performed using representative splits of the resulting 250g pulp. Process_Date: 2011 Process_Step: Process_Description: Slab-XRF sample preparation - Preparation for samples analyzed by the University of Alaska Fairbanks (UAF) were cut into slabs at DGGS or UAF with a tile saw to fit in 37-mm-diameter sample holders. These slabs were then polished in the UAF Advanced Instrumentation Laboratory with an Ameritool Universal Heavy-Duty Grinder and Polishing Machine using first a 60-mesh diamond disk and finished with a 180-mesh diamond disk. Notable samples (for example, clast or grain size greater than ~3 mm, sample size less than 37 mm, or inhomogeneities) are described in the geochemical layer “Comments” column. Process_Date: 2011 Process_Step: Process_Description: Rare-earth-element sample preparation - Samples were prepared using the same methods and equipment as the trace-element samples; the rare-earth-element analyses were performed using representative splits of the resulting 250g pulp. Process_Date: 2011 Process_Step: Process_Description: Trace-element analysis - All potentially mineralized samples were assayed for gold by inductive coupled plasma-atomic emission spectroscopy following a 30g fire assay fusion (FA-ICP-AES). Platinum and palladium were assayed for selected samples by FA-ICP-AES. Trace-element geochemical analyses were performed by inductive coupled plasma-atomic emission spectroscopy (ICP-AES) methods after four-acid, near-total digestion. This method of digestion is possibly incomplete for some elements and may result in lower analytical results for these elements. Analytical methods, lower and upper detection limits, and the elements that may be affected by incomplete digestion are noted in the attribute definition. Rock samples with trace-metal values above the detection limit in the initial trace-element geochemical analysis were reanalyzed for those metals by the following methods: gold, fire assay with a gravimetric finish using a 30g sub-sample (FA-GRAV); Phosphorus, by ICP-AES methods after high-grade four-acid, near-total digestion; and arsenic and/or zinc by ICP-AES methods after high-grade four-acid, near-total digestion. Analytical methods and detection limits are noted in the attribute definition Process_Date: 2011 Process_Step: Process_Description: Whole-rock analysis - Major and minor-element oxides were determined at ALS Chemex by X-ray fluorescence (XRF) spectrometry following a lithium borate fusion (LBM-XRF). Trace-element values for Cr, Nb, Ni, Rb, Sr, Y, and Zr were determined for mafic rocks by XRF on a pressed pellet. Trace-element values for Ba, Nb, Rb, Sr, Th, U, Y, and Zr were determined for felsic rocks by XRF on a pressed pellet. Analytical methods and detection limits are noted in the attribute definition. Process_Date: 2011 Process_Step: Process_Description: Non-carbonate-carbon analysis - Non-carbonate-carbon analyses were performed by ALS Chemex. Non-carbonate-carbon content was determined using a LECO furnace after a dilute acid digestion. The lower detection limit for non-carbonate carbon is 0.01 percent, and the upper detection limit is 50.00 percent. Process_Date: 20110 Process_Step: Process_Description: Slab XRF analysis - The XRF analyses were run on a PANalytical Axios spectrometer using SuperQ software. Nb, Rb, Sr, Y, and Zr were measured using SuperQ’s 37mmRbSrYZr routine software program; other elements were measured with the IQ+37mmVac software program. The 37mmRbSrYZr routine uses specific pre-determined peak and background positions for which x-ray intensities are measured for 2-800 seconds (depending on the element). The intensity of the Rh Compton peak is used to estimate mass-absorption coefficients (MACs) for both unknowns and well-characterized natural standards. Peak intensities are computed and converted to concentrations using calibration curves employing at least 10 natural rock standards. These procedures are routinely checked by analysis of secondary natural standards that were not employed in making the calibration curves. Elemental abundances are typically within 2-5% of the amount present for concentrations > 10 times the detection limit, within 5-10% of the amount present for concentrations 4-10 times the detection limit and within 30% of the amount present for concentrations near the detection limit. The IQ37mm Vac scans over a series of energies corresponding to a range from Ce-K? to O-K?. Peak heights and backgrounds, and X-Ray elemental interferences are picked with the software and checked manually to ensure quality control. Elemental abundances for all elements with atomic numbers between 8 and 92 are estimated from artificial standards and these estimations are used to calculate MACs for each element present above the detection limit. Revised concentrations are employed to calculate revised MACs until a stable solution is determined. Elemental abundances are then normalized to 100%. The software is routinely checked using pressed pellets of well-characterized natural rock standards. Elemental abundances are within 1-2% of the amount present for major elements, 2-5% of the amount present for minor elements, and 5-10% of the amount present for trace elements. Process_Date: 2011 Process_Step: Process_Description: Rare-earth-element analysis - values acquired by analysis with lithium meta-borate fusion and inductively coupled plasma - mass spectroscopy (LBF-ICP-MS). Analytical methods and detection limits are noted in the attribute definition. Process_Date: 2011 Process_Step: Process_Description: Other - Latitude and Longitude values were converted from UTM values by re-projecting the UTM coordinates with the "project" tool in the "data management" toolbox in ArcGIS Desktop 10.0 using ArcMap 10.0. After re-projecting the UTM coordinates, latitude and longitude were calculated with "Calculate Geometry" tool in the attribute table. Some accuracy may be lost in this conversion. In instances where analytical results fell outside the detection limits reported by the ALS Chemex, values were changed to "greater than detection limit" or "less than detection limit." In instances where detection limits reported in the ALS Chemex Schedule of Services and Fees differed from the detection limits reported in their Short Method Descriptions, the later values were documented in this report.
