Title:

Geochemical, major-oxide, minor-oxide, trace-element and carbon data from rocks collected in 2008 in the eastern Bonnifield mining district, Fairbanks and Healy quadrangles, Alaska

Abstract:

Mineral-resources personnel from the Alaska Division of Geological & Geophysical Surveys carried out a geological field survey, including mapping and sampling in the eastern part of the Bonnifield mining district in the Fairbanks A-1, A-2, Healy D-1 and D-2 quadrangles, Alaska from June 16 to July 18, 2008. 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 2008, 242 rock samples were collected for geochemical trace-element analysis, 106 rock samples were collected for whole rock (major- and minor-oxide and petrogenetically important trace element) analyses, and 7 samples were collected for analysis of non-carbonate carbon content.

Supplemental_Information:

The data are available in tabular format as comma delimited ascii files organized into three layers, each comprised of three tables as described in this metadata file under the "Entity_and_Attribute_Information" section. The layers are as follows:

Trace-element rock geochemistry: sample locations and descriptions, geochemical data, analytical methods and detection limits (Tables 1, 2, 5)
Whole-rock major-oxide, minor-oxide, trace-element: sample locations and descriptions, geochemical data, analytical methods and detection limits (Tables 3, 4, 6)
Non-carbonate carbon geochemistry: sample locations and descriptions, and geochemical data (Table 7)

To whom should users address questions about the data?

Why was the data set created?

Version 1.1 was released to correct several errors in the original version; please see the "Data Quality, Process Step" section below for specific errors and corrections. 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 Bonnifield airborne geophysical surveys released by DGGS in 2007 (Burns et al., 2007). 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.

How was the data set created?

From what previous works were the data drawn?
How were the data generated, processed, and modified?

Date: Jul-2008 (process 1 of 12)
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.

Date: Jul-2008 (process 2 of 12)
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.

Date: Jul-2008 (process 3 of 12)
Fieldwork - 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.

Date: Oct-2008 (process 4 of 12)
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.

Date: Nov-2008 (process 5 of 12)
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 5. All rock trace metal analyses were performed by ALS Chemex.

Date: Nov-2008 (process 6 of 12)
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.

Date: Nov-2008 (process 7 of 12)
Analysis - Any rock sample that contained trace metal values in the the initial trace element geochemical analysis were reanalyzed for the metals that were above detection by the following methods: Au, Fire assay with a gravimetric finish using a 30 gram sub-sample, Ba, using X-ray fluorescence after lithium meta-borate fusion, Sb, Atomic Absorption spectomescopy after a hydochloric acid - potasium perclorate digestion, and Ag, As, Cu, Pb, and/or Zn by inductive coupled plasma-atomic emission spectroscopy (ICP-AES) methods after four-acid, near-total digestion All rock trace metal analyses were performed by ALS Chemex.

Date: Nov-2008 (process 8 of 12)
Analysis - All rock samples for non-carbonate carbon content were digested using a dilute acid on a 1 gram sample charge, followed by combustion in a LECO furnace. at ALS Chemex Laboratory.

Date: Dec-2009 (process 9 of 12)
Analysis - All whole rock trace element analyses were performed at the University of Alaska Fairbanks on a pressed pellet prepared from a sample pulp provided by ALS Chemex, analysis was completed using a wavelength dispersive X-ray fluorescence spectrometer.

Date: Sep-2009 (process 10 of 12)
Other - Latitude and Longitude values in Tables 1,3, and 7 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>.

How reliable are the data; what problems remain in the data set?

How well have the observations been checked?
All rock geochemical and whole rock analyses were performed by by ALS Chemex. 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 5. Whole rock major and minor oxide 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). Whole-Rock trace element analyses of rock samples in Table 4 were performed by the University of Alaska Fairbanks Advanced Instrumentation Laboratory; trace element concentrations were determined by X-ray fluorescence spectrometry of a pressed pellet. Analytical methods and detection limits of analyses in Table 4 are tabulated in Table 6. Non-carbonate carbon analyses (Table 7) were performed by ALS Chemex by induction furnace pyrolysis following dilute acid digestion.
How accurate are the geographic locations?
Location data were downloaded from Garmin 12XL GPS units into an Access database. 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.
How accurate are the heights or depths?
Where are the gaps in the data? What is missing?
This dataset contains all (with one exception) 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 eastern Bonnifield project area in the summer of 2008.
How consistent are the relationships among the observations, including topology?
No topologic relationships are present in data.
