Errata

In Open File Report 6271, Report of Activities 2011, Resident Geologist Program, Red Lake Regional Resident Geologist Report: Red Lake and Kenora Districts (released April 3, 2012), omissions and errors were noted in Figure 13 and Table 13 (page 33) of the “Red Lake Regional Resident Geologist (Red Lake District)—2011” report. In Figure 13, the channel sample location labels were omitted, and incorrect channel sample symbols had been added. In Table 13, the assay values for sample 2010SM-27 were omitted, and the lengths of the channel samples were not provided.

These omissions and errors have been corrected, and a replacement page is available. Please contact Publication Sales and the replacement page will be sent to you free of charge. Alternatively, you may download the corrected version of Open File Report 6271 from our GeologyOntario Web site. (notice issued: August 2, 2016)

  • Three (3) files were incorrectly named in GDS 1248 and in the report (in “Appendix E. GeoTIFF and Vector Archive Definition” (p.23)). The following file names have been corrected.

  • For Block 4 (“Block B Discovery East”), data in the final longitudinal and lateral gradients channels (channel names MAG_GRAD_LAT_FINAL and MAG_GRAD_LONG_FINAL) were switched. The affected flight-line numbers are L9010 to L10030. The described error is present in ASCII profile database MOOSONEE.XYZ and in Geosoft® binary profile database MOOSONEE.GDB. The final longitudinal and lateral gradients data for the affected flight lines have been corrected in the profile databases.
    • All Geosoft® binary (.grd) and ASCII (.gxf) versions of the grids have been updated.
    • The GeoTIFF (.tif) files have been corrected.
    • The Keating correlation coefficients profile databases for both Geosoft® binary (.gdb) and ASCII (.csv) versions have been updated.
    • Among vector files, the Keating correlation coefficients and residual magnetic contour lines have been corrected.
  • An incorrect channel was used to create residual of the total magnetic field (MOMAG83) grids. Both Geosoft® binary (.grd) and ASCII (.gxf) versions of the grid have been updated with the correct channel.

These errors have been corrected and a replacement version of this Geophysical Data Set is available. If you have purchased a copy of this data set where your files do not match the file attributes shown above, please return the original DVD to Publication Sales, and a replacement copy will be sent to you free of charge. Alternatively, you may visit the GeologyOntario application to obtain the corrected version of Geophysical Data Set 1248.

We regret any inconvenience these errors may have caused.
