Title:

Trace element geochemical data from reanalysis of stream-sediment samples collected in 1981 from the Fairbanks mining district, Alaska

Abstract:

The geochemical analyses in this report result from the reanalysis of 932 archived stream-sediment pulps from the northern Fairbanks D-1, northern Fairbanks D-2, Fairbanks D-3 and southern Livengood A-1 and A-2 Quadrangles. The original geochemical data set included 1013 stream-sediment samples, (Albanese, 1982a-c).

Supplemental_Information:

Attribute information for the following tables (entities) is included in this metadata file under the "Entity_and_Attribute_Information" section. Each table is listed and described in detail under its own heading starting "Entity_Type_Label." Tables include:

table1_locations    locations of reanalyzed stream sediments
table2_geochem    concentration of trace elements in reanalyzed stream sediments
table3_methods    detection limits and analytical methods

Items in the Sample_Number field (a unique sample identifier present in Tables 1 and 2) are based on the following generic example: FBXYY-QQ_9999-X: FBX = Fairbanks, YY = last two digits of year, QQ = Quadrangle sample located in either Fairbanks or Livengood area, 9999=unique station number, X=unique alpha or numerical character designating which sample out of many was taken at the field station. Also X = R,S where R=Rock or S=Sediment. Used when two samples are at the same location but different types of material was sampled.

Who also contributed to the data set?

The data set was funded by the State of Alaska in conjunction with the 1995 Fairbanks STATEMAP geologic mapping project.
To whom should users address questions about the data?

Why was the data set created?

This publication contains unpublished geochemical data from part of geological and mineral investigations of the Fairbanks Mining District funded by the State of Alaska through the Fairbanks North Star Borough, and conducted by the Alaska Division of Geological & Geophysical Surveys (DGGS), Mineral Industry Research Laboratory (MIRL), University of Alaska and Department of Geology and Geophysics, University of Alaska Fairbanks in 1995. The samples were collected during May-July 1981. Original analyses with limited suite of elements was conducted in 1981 (Albanese, 1982a-c). The reanalysis contains a more extensive suite of elements using Instrumental Neutron Activation, Inductively Coupled Plasma and Atomic Absorption Analyses.

How were the data generated, processed, and modified?
Date: 1981 (process 1 of 4)
Field work: Samples were collected from May-July 1981 by DGGS staff members T.E. Smith, T.K. Bundtzen, M.S. Robinson, M.D. Albanese, D.N. Solie, V.M. Ferrell, G.M. Laird, J.D. Blum, M.H. Hall, J.D. Clough, and S.A. Liss; MIRL staff members P.A. Metz and B.W. Campbell; and D.B. Hawkins of the University of Alaska. A brief introduction and original tables can be found in Albanese (1982a, 1982b, 1982c). Additional collection information is unavailable.
Data sources used in this process:
- Albanese (1982a)
- Albanese (1982b)

Date: 1981 (process 2 of 4)
1981 Lab work: The pulps were prepared at the DGGS Geochemical Laboratory in 1981 by air-drying before screening for the -80 (180 micron) mesh fraction. Copper, lead, zinc, gold, silver, and molybdenum were analyzed at the DGGS laboratory by atomic-absorption spectrophotometry with a lower detection limit of 0.01 ppm. DGGS laboratory staff involved in these analyses include M.A. Wiltse, D.R. Stein, N.C. Veach, M.R. Ashwell, T.A. Benjamin, M.K. Polly, C.L. Smith, and S.W. Seed. Tin, tungsten, mercury, and arsenic were analyzed by Bondar-Clegg & Co. Ltd., Vancouver, B.C. Tungsten and arsenic were analyzed by coulometry with a lower detection limit of 2 ppm. Mercury was analyzed by cold-vapor atomic-absorption spectrophotometry with a lower detection limit of 5 ppb. Tin was analyzed by X-ray fluorescence with a lower detection limit of 5 ppm. A brief introduction and original tables can be found in Albanese (1982a, 1982b, 1982c).
Data sources used in this process:

Date: Unknown (process 3 of 4)
Storage: After initial analysis by the DGGS lab in 1981, the pulps were stored outside the DGGS warehouse under a tarp until they were brought to the DGGS lab to be re-packaged and sent out for analysis in 1995.

Date: 1995 (process 4 of 4)
1995 Lab work: All trace-element geochemical reanalyses (Table 2) were performed on pulps by Bondar-Clegg. A suite of 34 trace elements were analyzed by Instrumental Neutron Activation Analysis (INAA) and a suite of 33 trace elements were analyzed by Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES) after HF-HNO3-HClO4 acid digestion with HCl leach (four-acid, near-total digestion). This method of digestion is possibly incomplete for certain elements and may result in lower analytical results. The elements with possible incomplete digestion are Ba, Cr, Ti and W. Additional partial digestion of certain elements is not known for the year 1995. In addition, bismuth was analyzed by Atomic Absorption (AA) after hydride generation. Elements analyzed by each method and analytical detection limits are tabulated in Table 3.

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

How well have the observations been checked?
All trace-element geochemical reanalyses were performed on pulps by Bondar-Clegg in 1995. The pulps were prepared at the DGGS Geochemical Laboratory in 1981 by air-drying before screening for the -80 (180 micron) mesh fraction. After initial analysis by the DGGS lab in 1981, the pulps were stored outside the DGGS warehouse under a tarp until they were brought to the DGGS lab to be re-packaged and sent out for analysis in 1995. A suite of 34 trace elements were analyzed by Instrumental Neutron Activation Analysis (INAA) and a suite of 33 trace elements were analyzed by Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES) after HF-HNO3-HClO4 acid digestion with HCl leach (four-acid, near-total digestion). This method of digestion is possibly incomplete for certain elements and may result in lower analytical results. The elements with possible incomplete digestion are Ba, Cr, Ti and W. Additional partial digestion of certain elements is not known for the year 1995. Bismuth was analyzed by Atomic Absorption (AA) after hydride generation. Elements analyzed by each method and analytical detection limits are tabulated in Table 3.
How accurate are the geographic locations?
Location data were determined by two methods: on-screen digitizing sample locations using ArcGIS v9.1 from the original field maps onto spatially registered topographic maps downloaded from Alaska Geospatial Data Clearinghouse; or using the published locations in Albanese (1982a-c). Location data (in UTM coordinates with a Clark 1866, NAD27, UTM zone 6 projection) are presented in Table 1.
How accurate are the heights or depths?
Where are the gaps in the data? What is missing?
This dataset contains all of the samples selected for trace-element geochemical reanalyses in the Fairbanks and Livengood quadrangles during the summer of 1981.
How consistent are the relationships among the observations, including topology?
No topologic relationships are present in the data.
