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 geological mapping. During 2010, 130 rock samples were collected for geochemical trace-element analysis, and 20 rock samples were collected for whole rock (major- and minor-oxide) analysis. Petrogenetically important trace elements for additional rock samples will be analyzed and published with the final map and report for this area. The analyses in this report were acquired as part of a geologic mapping program, the purpose of which is to provide 1:63,500-scale geologic mapping of a portion of the Livengood airborne geophysical surveys released by DGGS in 1999 (DGGS et al., 1999). 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. The data are available in tabular format as comma delimited ascii files organized into two layers as described in this metadata file under the "Entity_and_Attribute_Information" section. The layers are as follows: >trace-element-samples sample number with location and description, geochemical data, analytical methods and detection limits of data ('trace-element-samples.csv' of the digital data distribution package). In print format these data are separated into three separate tables in order to facilitate more efficient printing: Table 1 contains sample number with location and description; Table 2 contains all analytical data of trace-element analyses; Table 5 summarizes the analytical limits and methods. >whole-rock-samples sample locations and descriptions, geochemical data, analytical methods and detection limits ('whole-rock-samples.csv' of the digital data distribution package). In print format these data are separated into three separate tables in order to facilitate more efficient printing: Table 3 contains sample number with location and description; Table 4 contains all analytical data of major- and minor-oxide, and trace-element analysis; Table 6 summarizes the analytical limits and methods. 20100609 20100630 ground condition In work None planned -148.99900 -148.24700 66.49890 65.26300 ISO 19115 Topic Category geoscientificInformation None Geochemistry Minor Oxides Major Oxides Trace Metals None Alaska, State of Tolovana River West Fork Tolovana River Livengood Quadrangle Livengood Cascaden Ridge Shorty Creek Wilber Creek Livengood Creek Ester Creek Olive Creek Cleary Creek Steel Creek McCord Creek Winter Creek Ranney Hollow Slate Creek Eagle Creek Brooks Creek Tolovana Hot Springs Dome Tolovana Hot Springs Elliot Highway Trans-Alaska Pipeline None Cambrian Cretaceous Devonian This report, map, and/or dataset are available directly from the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (see contact information below).

Trace-element geochemical analyses (Table 1) on rock samples were performed by inductive coupled plasma-atomic emission spectroscopy (ICP-AES) and inductive coupled plasma-mass spectroscopy (ICPMS) 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 1. Whole rock analyses (Table 2) were performed by ALS Chemex. Major and minor element oxides were determined by X-ray fluorescence spectrometry following a lithium borate fusion (WEI-GRA06). Trace-element analysis of whole rock samples were determined by pressed-pellet X-ray fluorescence spectrometry. Analytical methods and detection limits are tabulated in Table 2. No topologic relationships are present in data. Sample distribution was dependant on outcrop availablability and rock suitability. This dataset contains all of the analyses for samples collected for trace-element rock geochemistry, and whole rock major- and minor-oxide, and trace-element geochemistry in the Livengood South project area in the summer of 2010.Petrogenetically important trace-elements will be analyzed by the Advanced Instrumentation Laboratory at the University of Alaska Fairbanks (UAF) to be published with the final map and report for this area. Location data were downloaded from Garmin 12XL GPS units into an Access database. 6 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. Fieldwork - Rock samples were collected in conjunction with geologic mapping throughout the map area. Samples collected specifically for trace element analysis exhibited visible mineralization or features associated with mineralization. Rock samples collected for major-oxide, minor-oxide, and trace elements include samples representative of a typical lithology, igneous or possible meta-igneous samples. Unweathered or minimally weathered rock samples were preferentially selected for analysis. Sample location points were entered into Garmin 12XL units. 201006 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. 201008 Analysis - Initially, all rock samples for trace-element geochemistry (Table 1) 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) and inductive coupled plasma-mass spectroscopy (ICP-MS) 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 1. All rock trace metal analyses were performed by ALS Chemex. 201008 Analysis - All whole rock analyses (Table 2) were performed by ALS Chemex. Major and minor element oxides were determined by X-ray fluorescence spectrometry following a lithium borate fusion (WEI-GRA06). Trace-element geochemical analyses were determined by X-ray fluorescence spectrometry.Analytical methods and detection limits are tabulated in Table 2. 201008 Other - Latitude and Longitude values presented in this report were converted from UTM values using Corpscon ver. 6.0.1, a program created by the U.S. Army Corps of Engineers, Engineer Research and Development Center, Topographic Engineering Center, Alexandria, VA, http://www.tec.army.mil. 201010 Point Universal Transverse Mercator 6 1 -147.000 0 500000 0 coordinate pair 1 1 meters whole-rock-samples Universal Transverse Mercator 6 1 -147.000 0 500000 0 coordinate pair 1 1 meters trace-element-samples North American Datum of 1927 Clarke 1866 6378137 298.25722210088 trace-element-samples trace-element-samples.csv Location and description of rock samples, analytical data, detection limitis and methods for trace-element geochemical analyses in the Tolovana mining district, Livengood Quadrangle, Alaska Alaska Division of Geological & Geophysical Surveys and ALS CHEMEX Sample Number Unique sample identifier Alaska Division of Geological & Geophysical Surveys Generic example of unique sample identifier: 20YYAAA9999X: YY=last two digits of year, AAA=geologist's initials (one to three characters), 9999=unique station number, X=unique alpha character designating a sample was taken at the field station.
