British Columbia is suited for using
drainage geochemistry to find new mineral resources. As a result the
British Columbia Geological Survey started a regional stream sediment and
stream water geochemical survey (RGS) in 1976 as part of the Geological
Survey of Canada National Geochemical Reconnaissance Program. This survey
now covers about 70 percent of the province with field and analytical data
from the collection and analysis of over 55 000 stream sediment, lake
sediment, moss mat sediment and surface water samples.
Geofile 2008-1 is
an atlas of gold, arsenic, cobalt, copper, iron, manganese, molybdenum,
nickel, lead, uranium and zinc geochemical maps created from the analyses of
stream, lake and moss sediment samples collected throughout British
Columbia. Background variations between some of the elements in the
different samples types have been reduced by adjusting the source data using levelling procedures. The atlas maps are accompanied by element data files
and documentation.
All publications of the BC Geological Survey are available
for purchase through Crown Publications Inc. (and its agents).
