Title:
Major-oxide, minor-oxide, and trace-element geochemical data from rocks collected in the Alaska Highway corridor, Mount Hayes, Tanacross, and Nabesna quadrangles, Alaska, in 2006, 2008, 2009, and 2010
Abstract:
Geologists from the Alaska Division of Geological & Geophysical Surveys (DGGS) and the University of Alaska Fairbanks (UAF) carried out geologic field surveys, including bedrock mapping and sampling, in the Alaska Highway Corridor from 2006 through 2010. The fieldwork provides basic information critical to building an understanding of Alaska's geology and is part of a broader, integrated program that includes airborne geophysical surveys, bedrock and surficial mapping, a mineral-resource assessment, a geologic-hazards assessment, and other geological studies. This publication contains descriptive, location, and analytical information for samples collected in the Mount Hayes, Tanacross, and Nabesna quadrangles, Alaska, in the summers of 2006, 2008, 2009, and 2010. Additional analytical data for samples collected in the Mount Hayes Quadrangle in the summers of 2006 and 2007 were published in a separate report. During the field seasons covered by this report, rock samples were collected for geochemical trace-element and whole-rock (major- and minor-oxide and petrogenetically important trace-element) analyses. Rock sample location coordinates are presented in decimal degree latitude and longitude based on the North American Datum of 1927 (NAD 27) for Alaska. Brief sample descriptions are based principally on field observations with some thin-section details added.
Supplemental_Information:
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 and correspond to subdirectories within the data distribution package. The metadata layer provides an FGDC metadata file and may include other documentation files. Attribute information for each data layer is described in this metadata file under the "Entity_and_Attribute_Information" section. Data layer contents:
border: a polygon that encompasses the maximum geographic extent of the data observations
rock-major-minor-oxide-trace-element: major- and minor-oxide and petrogenetically important trace-element analytical results
rock-trace-element: geochemical trace-element analytical results

Why was the data set created?

Geologists from the Alaska Division of Geological & Geophysical Surveys (DGGS) and the University of Alaska Fairbanks (UAF) carried out geologic field surveys, including bedrock mapping and sampling, in the Alaska Highway Corridor from 2006 through 2010. The fieldwork provides basic information critical to building an understanding of Alaska's geology and is part of a broader, integrated program that includes airborne geophysical surveys, bedrock and surficial mapping, a mineral-resource assessment, a geologic-hazards assessment, and other geological studies. This publication contains descriptive, location, and analytical information for samples collected in the Mount Hayes, Tanacross, and Nabesna quadrangles, Alaska, in the summers of 2006, 2008, 2009, and 2010. During the field seasons covered by this report, rock samples were collected for geochemical trace-element and whole-rock (major- and minor-oxide and petrogenetically important trace-element) analyses.


How was the data set created?

  1. From what previous works were the data drawn?

  2. How were the data generated, processed, and modified?

    Date: 2010 (process 1 of 4)
    Sample collection - Samples of visibly mineralized rock, or rocks exhibiting features commonly associated with mineralization, were collected by DGGS geologists for geochemical trace-element analyses. Additional rock samples from igneous rocks and metamorphic rocks of possible igneous origin were collected for major oxides, minor oxides, and trace elements. Weathered surfaces were either removed in the field with a rock hammer, or later trimmed off with a rock saw.

    Date: 2010 (process 2 of 4)
    Sample preparation - Trace-element geochemical analyses and whole-rock analyses were performed by ALS Chemex (ALS) and the Advanced Instrumentation Laboratory at the University of Alaska Fairbanks (UAF). All rock samples were crushed by ALS 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 and 30 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. All trace-element geochemical analyses and whole rock analyses were performed using representative splits of each 250-gram pulp, except gold, platinum, and palladium analyses, which were performed on a 30-gram representative split. In 2008, a second 250-gram pulp was prepared at ALS for whole-rock analyses at UAF. All hand samples and leftover pulps are retained by DGGS, and will be stored at the Geologic Materials Center in Anchorage.

    Date: 2009 (process 3 of 4)
    Major oxide and selected trace elements - For the whole-rock analyses, major- and minor-element oxides were determined by ALS using X-ray fluorescence spectrometry following a lithium borate fusion. Selected trace-element values (Ba, Nb, Rb, Sr, Y, and Zr) were determined by X-ray fluorescence spectrometry on a pressed pellet at ALS for samples collected in 2006 and 2009, and by UAF for samples collected in 2008. XRF spectroscopic analyses performed at the Advanced Instrumentation Laboratory at UAF were conducted on pressed pellets. At UAF, pressed pellets of well-calibrated international standards were used as a check of the trace-element analyses. In order to check reported major- and minor-element oxide and trace-element values, DGGS inserts well-characterized rock standards in each laboratory batch throughout the sample order. Standards are checked by DGGS to make sure they fall within 2 standard deviations of accepted values, and if not, all samples in the batch are reanalyzed. Note that additional information, including method detection limits and related references, can be found in the accompanying report and in the lab documentation provided with this digital download.

    Date: 2010 (process 4 of 4)
    Trace-elements - All potentially mineralized samples were assayed for gold by inductively coupled plasma-atomic emission spectroscopy (ICP-AES) following a 30-g fire assay fusion (FA), after four-acid, near-total digestion. Rock samples collected in 2008 and 2009 with the potential for elevated platinum-group-element content were assayed for gold, platinum, and palladium by 30-gram fire assay and inductively coupled plasma-mass spectrometry (ICP-MS) finish after four-acid, near-total digestion in 2008, and by 30-g fire assay and ICP-AES finish after four-acid, near-total digestion in 2009. All other trace-element geochemical analyses, from all years, were performed by 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. Methods and detection limits for each type of analysis are tabulated in the digital data distribution files. To check reported trace-element geochemical assay values, DGGS inserts well-characterized standards in each laboratory batch throughout the sample order. Standards are checked by DGGS to make sure they fall within 2 standard deviations of accepted values, and if not, all samples in the batch are reanalyzed. Note that additional information, including method detection limits and related references, can be found in the accompanying report and in the lab documentation provided with this digital download.

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

  1. How well have the observations been checked?

    In addition to ALS Chemex/Minerals' internal quality-control program accredited to ISO/IEC 17025-2005 standards, DGGS monitored analysis quality by inserting igneous-rock and ore-geochemical-pulp standards with known compositions into the sample roster for every sample batch. We report measured values which are above or below instrument detection limits when they are provided to us by the originating lab. Users should contact the originating labs for additional information about detection limits and reporting procedures. Brief sample descriptions are based principally on field observations with some thin-section details added. In some cases the sample numbers sent to the lab were later determined to be incorrect or non-standard. We report both the samples numbers provided to the lab and the corrected sample number.

  2. How accurate are the geographic locations?

    Location data were downloaded from handheld Garmin GPS units (76C and 12XL) into an Access database. Estimated position error calculated by the GPS units was not better than 3 meters and was less than 10 meters.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    For additional geochemistry data collected by Alaska Highway corridor project, users should also see DGGS report: RDF 2008-2 v. 1.0.1.

  5. How consistent are the relationships among the observations, including topology?

    not applicable
