Geoscience BC Releases Two Reports: Ice Flow maps (NTS 093G, H & J), and New ICP-MS Geochemistry (NTS 082F)

March 14, 2013 - Geoscience BC is pleased to announce the release of the following two reports:
  • Report 2013-08: Ice Flow Patterns in NTS 093G, H (west half) & J, and Detailed Ice Flow History for NTS 093J/05, /06, /11, /12, /13 & /14
  • Report 2013-09: Nelson (NTS 082F) Sample Reanalysis (ICP-MS)

Both reports are now available for download through Geoscience BC's website at

Brief descriptions of each report are provided below.

Geoscience BC Report 2013-08: Ice Flow Patterns in NTS 093G, H (west half) & J, and Detailed Ice Flow History for NTS 093J/05, /06, /11, /12, /13 & /14

The maps contained within this report show ice flow patterns for NTS 093G, H (west) and J, and detailed ice flow history for parts of NTS 093J (near Prince George, BC). The report also contains a regional ice flow model for the northern Interior Plateau region. Constructed from previous mapping and recent field studies, the report is intended as an aid to mineral exploration in central BC. The report consists of one PDF sheet, and the ESRI ArcGIS shapefiles of striations, regional ice flow and detailed ice flow data.

Geoscience BC Report 2013-09: Nelson (NTS 082F) Sample Reanalysis (ICP-MS)

Geoscience BC Report 2013-09 presents new ICP-MS results for stream sediment samples originally collected during the 1977 Nelson RGS program. New ICP-MS results for stream sediment samples collected in the 1977 Lardeau RGS program were released in January 2013 as Geoscience BC Report 2013-04.

The original Nelson regional geochemical survey included the collection of 1394 stream sediment samples. In co-operation with the BC Geological Survey and Natural Resources Canada, samples saved from the survey work were retrieved from storage facilities in Ottawa. A total of 1554 drainage-sediment and quality-control samples were subsequently delivered to Acme Analytical Laboratories Ltd. (Vancouver, BC) and analyzed by an ultra-trace aqua-regia digestion (0.5 g) ICP-MS technique for 53 elements.

ICP-MS results will be provided in a Microsoft® Excel file. The data have been carefully checked for analytical quality using blind duplicate samples and control reference material. Reanalysis data determined to be complete and accurate were merged with sample site location information acquired from the original survey publication. Routine comparison of the original determinations with the ICP-MS analyses for elements such as copper, lead, nickel and zinc, identified inconsistencies in some samples. As a result, ICP-MS data for 382 samples have been removed from the data set until further investigations can be completed.
