The fieldwork provides basic information critical to building an understanding of Alaska geology and is part of an integrated program of airborne geophysical surveys followed by geological mapping. During 2007, 128 rock samples were collected for geochemical trace-element analysis, and 44 rock samples were collected for whole rock (major- and minor-oxide) analysis. Petrogenetically important trace-elements will be analyzed in a subsequent study to be published with the final map and report for this area. In addition, 67 stream sediment samples were collected for geochemical trace-element analysis. The stream sediment geochemical study was conducted over the proposed Mount Ryan Remote Recreational Cabin Staking Area as considered by Alaska's Division of Mining, Land & Water in 2007. Purpose: The analyses in this report were acquired as part of a geologic mapping program, the purpose of which is to provide 1:50,000-scale geologic mapping of a portion of the Northeast Fairbanks airborne geophysical surveys released by DGGS in 2006 (Burns et al., 2006). 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 planning.

Stream sediment geochemical analyses were performed by performed by Alaska Assay Laboratories (sample preparation) and Acme Labs (analyses). Rock samples were assayed for gold by inductive coupled plasma-atomic emission spectroscopy following a 30g fire assay fusion (FA-ICP). Trace-element geochemical analyses on rock samples 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. The elements that may be affected by incomplete digestion, analytical methods, and lower and upper reporting limits are tabulated in Table 7. Whole rock analyses (Table 4) were performed by ALS Chemex. Major and minor element oxides were determined by X-ray fluorescence spectrometry following a lithium borate fusion (WEI-GRA06). Analytical methods and detection limits are tabulated in Table 8. Stream sediment samples were assayed for gold by inductively coupled plasma-mass spectrometry (ICP-MS) following Aqua-Regia digestion. Trace element geochemical analyses were performed by ICP-MS methods after four-acid, near-total digestion. Digestion involved heating a 0.25 g split in HNO3-HClO4-HF to fuming and then taking it to dryness. The residue was dissolved in HCl. This method of digestion is possibly incomplete for some elements and may result in lower analytical results for these elements. In addition, some loss of certain elements may result from volatilization during fuming. The elements that may be affected by incomplete digestion and volatilization, analytical methods, and lower and upper detection limits are tabulated in Table 9. Logical_Consistency_Report: No topologic relationships are present in data. Completeness_Report: This dataset contains all of the analyses for samples collected for trace-element rock geochemistry, whole rock major and minor oxide geochemistry, and trace element stream sediment geochemistry in the northeast Fairbanks project area in the summer of 2007. Whole-rock trace element analyses for rock samples will be determined by the Advanced Instrumentation Laboratory at the University of Alaska Fairbanks (UAF) and will be released at a later date. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Location data were downloaded from Garmin 12XL GPS units into an Access database. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 6 Horizontal_Positional_Accuracy_Explanation: A value of estimated position error in meters was calculated by Garmin 12XL GPS units and recorded for each sample location. Estimated position error calculated by Garmin 12XL units was not better than 3 meters and averaged approximately 6 meters. The GPS system suffers from calculation and geometric error. This error results from items such as error in satellite positions, mathematical error introduced by the formulas used by the GPS unit for calculating 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 - 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. Unweathered or minimally weathered rock samples were preferentially selected for analysis. Process_Date: 200706 Process_Step: Process_Description: Fieldwork - Rock samples collected for major-oxide, minor-oxide, and trace elements include samples representative of a typical lithology, igneous or possible meta-igneous samples in order to determine composition, and samples whose petrogenetically important trace-elements could indicate their original tectonic setting. Unweathered or minimally weathered rock samples were preferentially selected for analysis. Spatially these rocks were collected randomly. Process_Date: 2007 Process_Step: Process_Description: Fieldwork - Stream sediment samples were collected from first-order streams just above the confluence with second-order streams, except for sample 07Z440.1B that was taken from a second-order stream. Silt- and clay-sized (-80 mesh) sediment was preferentially sampled from active stream channels, at or below water level. Samples were collected from gravel and sand bars where possible, and obvious coarse sand, organic-rich material, and loess were avoided. Pebbles and large organic debris was removed from the sample using a ¼ inch sieve. Samples were collected over a 15- to 30-meter stretch of the stream. Sample size was generally half or more of a 7-inch by 11-inch sample bag containing sand-sized or finer material. Process_Date: 200706 Process_Step: Process_Description: Sample Preparation - Rock samples were crushed with a Terminator oscillating jaw crusher with chrome steel alloy plates so that at least 70 percent of the material passes 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 a chrome steel ring mill so that 85 percent of the sample passed through a -200 mesh (75 micron) screen. Trace-element analyses, the whole rock major element analyses and the gold analyses were performed using representative splits of each 250 gram pulp. Sample preparation was conducted at the ALS Chemex sample preparation facility in Fairbanks, Alaska. Process_Date: 2007 Process_Step: Process_Description: Sample Preparation - Sediment samples were dried and sieved to -80 mesh (2 mm) material by stainless steel screens. Representative aliquots of 250 grams were taken using a stainless steel riffle splitter. These samples were then pulverized in a chrome steel ring mill so that 85 percent of the sample passed through a -200 (75 micron) mesh screen. Most trace-element analyses were performed on a 0.25 gram split while gold analyses were performed on a 15 gram representative split. Sample preparation was conducted by Alaska Assay Laboratories at Fairbanks, Alaska. Process_Date: 2007 Process_Step: Process_Description: Analysis - Initially, all rock samples for trace element geochemistry (Table 2) were assayed for gold by inductive coupled plasma-atomic emission spectroscopy following a 30g fire assay fusion (FA-ICP). 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. The elements that may be affected by incomplete digestion, analytical methods, and lower and upper reporting limits are tabulated in Table 7. All rock trace metal analyses were performed by ALS Chemex. Process_Date: 2007 Process_Step: Process_Description: Analysis - All whole rock analyses (Table 4) were performed by ALS Chemex. Major and minor element oxides were determined by X-ray fluorescence spectrometry following a lithium borate fusion (WEI-GRA06). Analytical methods and detection limits are tabulated in Table 8. Process_Date: 2007 Process_Step: Process_Description: Analysis - Stream sediment samples (Table 6) were assayed for gold by inductively coupled plasma-mass spectrometry (ICP-MS) following Aqua-Regia digestion. Trace element geochemical analyses were performed by ICP-MS methods after four-acid, near-total digestion. Digestion involved heating a 0.25 g split in HNO3-HClO4-HF to fuming and then taking it to dryness. The residue was dissolved in HCl. This method of digestion is possibly incomplete for some elements and may result in lower analytical results for these elements. In addition, some loss of certain elements may result from volatilization during fuming. The elements that may be affected by incomplete digestion and volatilization, analytical methods, and lower and upper detection limits are tabulated in Table 9. Analyses of stream sediment samples where conducted by Acme Labs of Vancouver, B.C. Canada.

Overview_Description: Entity_and_Attribute_Overview: RDF 2008-1 has nine entities containing attributes that need to be defined. The entities are grouped in three thematic layers; each layer contains a sample location and description table (Tables 1, 3, and 5), a geochemical analysis data table (Tables 2, 4, and 6), and table describing analytical methods and detection limits (Tables 7, 8, and 9). The values in the "Sample Number" columns in tables 1, 4, and 7 correspond with the "Sample Number" columns in in tables 2, 5, and 8, respectively. Each row in tables 3, 6, an 9 give detection limits and methods for each of the columns in tables 2, 6, and 8 respectively.
