NTS 92G - Vancouver / RGS 26 / GSC OF 2184 / GBC R2011-4

The Vancouver (NTS 92G) reconnaissance-scale stream sediment and water survey was completed in 1989 and the resulting field and analytical data were released in 1990. A total of 978 sediment and 848 water samples were collected from 924 sample sites. Moss-mat sediment was collected from 11 sites on Vancouver Island.

 

Geoscience BC Report 2011-4 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.
