GSC OF 514/NGR 25/GSC OF 2355 / BCGS OF 1990-11 / GBC 2013-09

The Nelson (NTS 82F) reconnaissance-scale stream sediment and water survey was completed in 1977 and the resulting field and analytical data were released in 1978. A total of 1394 sediment and 1382 water samples were collected from 1318 sample sites.

 

As part of the RGS Archive Program, 1371 archived sediment pulps were re-analyzed by epi-thermal INAA and this new data along with original survey results were published in 1991.

 

British Columbia Geological Survey Open File 1990-11 presents analytical results for gold and 28 other elements from stream samples collected in the Purcell Wilderness Conservancy Study Area in southeastern British Columba.

 

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.
