Geologic datasets for weights-of-evidence analysis in northeast Washington--2. Mineral databases
Digital mineral databases are necessary to carry out weights-of-evidence modeling of mineral resources for epithermal gold and carbonate-hosted lead-zinc deposits in northeast Washington. This report describes four digital data sets (presented as separate sheets in tables.xls, an Excel97-format file) used for this modeling: 1) training sites for epithermal gold, 2) placer gold sites, 3) training sites for carbonate-hosted lead-zinc, and 4) small lead-zinc mines.
The Excel97 file, of99-384.xls, contains five (5) sheets corresponding to the five tables listed in the Open-File Report 99-384 text.
Table 1 in the text corresponds to the sheet titled 'Trainsites_epith'
Table 2 in the text corresponds to the sheet titled 'Placer_gold_sites'
Table 3 in the text corresponds to the sheet titled 'Trainsites_PbZn'
Table 4 in the text corresponds to the sheet titled 'Small_PbZn_Mines'
Table 5 in the text corresponds to the sheet titled 'Township_location'

    Table 1. Training sites for epithermal gold model File name: of99-384.xls; sheet name: Trainsites_epith
    The training sites consist of a collection of sites (either mines, prospects or occurrences) selected from MRDS or MAS/MILS database because of their epithermal gold-like characteristics. Sites were qualified for the epithermal gold model if they met the selection criteria below for any of the USGS models for Au-Ag hot spring, 25a (Berger, 1992), Creede epithermal veins, 25b (Mosier et al., 1992), or Comstock epithermal veins, 25c (Mosier, Singer and Berger, 1992). Minimum selection criteria are a) Sites are spatially associated with Eocene volcanic or hypabyssal rocks and b) Sites contain gold in quartz veins or disseminations.

    Table 2. Placer gold sites File name: of99-384.xls; sheet name: Placer_gold_sites
    Placer gold sites -- Indicates locations of mines or prospects of placer gold exploration or development. Selection criteria for the 67 sites obtained from MRDS and MAS/MILS were a)"gold" is the primary commodity and b) "placer" was indicated by the name, deposit type, or modifier of commodity. See definition of attributes from Table 1.

    Table 3. Training sites for carbonate-hosted lead-zinc model File name: of99-384.xls; sheetname: Trainsites_PbZn
    The training sites consist of sites (mines, prospects or occurrences) selected from MRDS or MAS/MILS, because they exhibit characteristics of explored or developed carbonate-hosted lead-zinc deposits. Sites were qualified as carbonate-hosted lead-zinc deposits if they met the selection criteria below for the USGS model for carbonate-hosted lead-zinc deposits (Briskey, 1992). Minimum criteria by which the 11 mines were selected are a) lead and zinc are the primary commodities; b) the deposit is either strataform, pipe-like, or breccia in form or replacement in nature; c) the deposit occurs within strata of either the Maitlen Phyllite of Cambrian age, the Metaline Formation of Cambro-Ordovician age, or the Ledbetter Slate of Ordovician age; and d) the mine has produced more than 100,000 tons of ore.

    Table 4. Small lead-zinc mines and prospects File name: of99-384.xls; sheet name: Small_PbZn_Mines
    Smaller deposits described as carbonate-hosted lead-zinc deposits are those where no ore was produced or had total production up to 100,000 tons. These smaller deposits were selected using the selection criteria used for training sites of carbonate-hosted lead-zinc deposits (Briskey, 1992) with the exception that the deposits from this group were selected because they had no commercial production or produced 100,000 tons or less of ore.
    Table 5. Township and range location for sites File name: of99-384.xls; sheet name: Township_location
    The township-range-section and latitude-longitude locations in this table are taken from the databases. For those not available, the Wefald script was used to calculate from available data. Some sites were checked against those listed by the Washington Department of Natural Resources (Derkey, R.E., Joseph, N.L., and Lasmanis, R., 1990)

  2. How were the data generated, processed, and modified?
    (process 1 of 2)
    The data was originally provided in two formats. The USGS MRDS was provided in an ACCESS database and was exported to EXCEL97 for purposes in this report 1998.

  3. What similar or related data should the user be aware of?

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

  1. How well have the observations been checked?
    Attribute accuracy was verified by manual comparison of MRDS record printouts with MAS/MILS record printouts to the extent possible.
  2. How accurate are the geographic locations?
    The horizontal positional accuracy for the digital data was not checked. The point locations given by the MRDS and MAS/MILS databases were not modified and were compared to determine the most accurate location.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    This digital dataset was produced from unpublished MRDS and MAS/MILS databases and is not considered to be a unique mineral resource dataset for the area.
