Geochemical Data Related to a Study of Platinum Group Element Mineralization in Nipissing Gabbro Intrusions and the River Valley Intrusion, Sudbury Region, Southern Province; by L.S. Jobin-Bevans. This digital release contains whole-rock geochemical data and assay data; field photographs, photomicrographs and back-scatter electron microscope images; and a summary of the project results. All these data were collected as part of a study of platinum group element (PGE) mineralization in Nipissing gabbro intrusions in the Southern Province in and around Sudbury, Ontario, between September 1996 and May 2004. This project was a collaborative effort between the Ontario Geological Survey, the Department of Earth Sciences at Laurentian University in Sudbury and the Department of Earth Sciences at the University of Western Ontario in London, Ontario, in support of a PhD thesis study by the author. This release comprises 104 images (as .jpg files), 2 Microsoft® Excel® 2010 (.xlsx) files and 6 documents in portable document format (.pdf). The data are available on 1 CD. $20.00.

Errata

In Aggregate Resources Inventory Paper 159, Aggregate Resources Inventory of the County of Oxford and the County of Brant, Southern Ontario (released April 15, 2014), errors were noted regarding the naming of certain feature classes within the geodatabase, “ARIP159.mdb”, provided with the vector files. A feature class intended for display purposes only (i.e., “Sand_Gravel_Client”) was incorrectly named as the feature class intended to be used (i.e., “Sand_Gravel”). Several feature classes were incorrectly named and have been renamed (see table). Also, in the attribute table for the “Gradation” layer, the content of the field “TABLE_REF” stated incorrectly “Refer to Table 2”, but should state “Refer to Table 10”. Please refer to the “ARIP159_readme” file for further information on the intended use of these files.

Geophysical Data Set 1082a

Ontario Airborne Geophysical Surveys, Magnetic Gradiometer and Gamma-Ray Spectrometric Data, Grid and Profile Data (ASCII Format) and Vector Data, Smooth Rock Falls Area

Original Release Date: April 27, 2016
Notification Date of Data Errata: May 31, 2016

Errors in Geophysical Data Set 1082a, Ontario Airborne Geophysical Surveys, Magnetic Gradiometer and Gamma-Ray Spectrometric Data, Grid and Profile Data (ASCII Format) and Vector Data, Smooth Rock Falls Area (released April 27, 2016), were discovered in the data set and the digital report as outlined below.

  • The latitude and longitude co-ordinates (channel names LAT_NAD83 and LON_NAD83) were incorrectly calculated for 10 flight lines comprising flight 491. The affected line numbers are 7550 to 7640. The UTM co-ordinates are unaffected. The described error is present in ASCII profile databases SRMAG.XYZ, SRSPEC.XYZ and SRSPEC256.XYZ. The latitude and longitude co-ordinates for the affected flight lines have been corrected in the profile databases.
  • The description of the SRMAG.XYZ profile database channel name “height_mag” is incorrectly described in the table on page 70 of the report (section 4. DATA FILES in APPENDIX C. Archive Definitions) as “metres above terrain”. It should read “metres above sea level ”. This description has been corrected.

Geophysical Data Set 1082b

Ontario Airborne Geophysical Surveys, Magnetic Gradiometer and Gamma-Ray Spectrometric Data, Grid and Profile Data (Geosoft® Format) and Vector Data, Smooth Rock Falls Area

Original Release Date: April 27, 2016
Notification Date of Data Errata: May 31, 2016

Errors in Geophysical Data Set 1082b, Ontario Airborne Geophysical Surveys, Magnetic Gradiometer and Gamma-Ray Spectrometric Data, Grid and Profile Data (Geosoft® Format) and Vector Data, Smooth Rock Falls Area (released April 27, 2016), were discovered in the data set and the digital report as outlined below.

  • The latitude and longitude co-ordinates (channel names LAT_NAD83 and LON_NAD83) were incorrectly calculated for 10 flight lines comprising flight 491. The affected line numbers are 7550 to 7640. The UTM co-ordinates are unaffected. The described error is present in Geosoft® binary profile databases SRMAG.GDB, SRSPEC.GDB and SRSPEC256.GDB. The latitude and longitude co-ordinates for the affected flight lines have been corrected in the profile databases.
  • The description of the SRMAG.GDB profile database channel name “height_mag” is incorrectly described in the table on page 70 of the report (section 4. DATA FILES in APPENDIX C. Archive Definitions) as “metres above terrain”. It should read “metres above sea level”. This description has been corrected.
  • Incorrect registration (.gi) files were supplied with the Geosoft® binary (.grd) versions of the following grids: SRGMAGGSC83.grd, SRG1VDMAGGSC83.grd, SRG2VDMAGGSC83.grd. The error resulted in the displacement of these grids from their correct positions by approximately 150 m northeast. The incorrect registration files have been replaced. This error did not affect the ASCII (.gxf) versions of these grids.
