Geoscience BC Releases Report 2011-4 "Regional Stream Sediment and Water Geochemical Data, Vancouver Island, British Columbia"

March 16, 2011 -This report was released as part of a Vancouver Island Geoscience Data Release Event, which was held in Port Hardy on March 16th. The event also featured the release of a 1:50,000 scale map of the Holberg - Winter Harbour Area by Graham Nixon of the BC Geological Survey, and a poster display of Geoscience BC's Northern Vancouver Island Compilation Project. The geoscientists responsible for each of these projects were on hand to discuss their projects and results.

Geoscience BC is pleased to announce the release of Report 2011-4: "Regional Stream Sediment and Water Geochemical Data, Vancouver Island, British Columbia" by W. Jackaman.

About Report 2011-4:
Geoscience BC has supported the reanalysis of moss-trapped stream sediment samples originally collected in the late 1980s from creeks on Vancouver Island by the BC Geological Survey and the Geological Survey of Canada. These samples have been recovered from storage and analyzed for 51 elements by aqua-regia digestion followed by inductively coupled plasma-mass spectrometry (ICP-MS) and Pt and Pd by fire assay.

This report contains results of the 2010 Vancouver Island Reanalysis project plus previously published data for gold, fluorine and loss on ignition in stream sediments and fluoride, uranium and pH in stream waters. This information has been provided in a variety of digital formats. PDF files include survey descriptions and details regarding methods, field and analytical data listings, summary statistics, sample location map, geology map and maps for individual metals. Raw digital data of original field and analytical information plus new reanalysis results are included in Excel (XLS) format.

Included on the report web page are links to supplementary airborne magnetic maps and images for Vancouver Island. These are derived from Natural Resources Canada aeromagnetic data, with image processing performed by P. Kowalczyk.
