2. Regional Silt Geochemistry
Most of the Yukon Territory, south of 66° N latitude has been silt sampled at approximately 1 sample for every 13 square kilometres. There are approximately 1100 samples for each 1:250 000 map area. Lake sampling has been undertaken in the Watson Lake area. Results are available as datafiles, reports and maps from the Geological Survey of Canada National Geochemical Reconnaissance.
Over the past year three stream sediment and water geochemical projects have been carried out and will be released in Spring, 2008 in the following open files:
GSC Open File 5695 - YGS Open File 2008-2
Geochemical data from a National Geochemical Reconnaissance stream sediment and water survey in the Nahoni Range area of west-central Yukon Territory (parts of NTS 116F, G and K)
A National Geochemical Reconnaissance (NGR) stream silt sediment and water survey was conducted during the 2006 field season roughly 200 km north of Dawson City in the southern Nahoni Mountains. Site specific field observations and silt and water analytical data for 355 sites will be published. Stream silt
sediment samples underwent ICP-MS and INA analyses producing data for 51 variables, while water samples were analysed by ICP-MS and ICP-ES generating data for 57 variables.
GSC Open File 5696 - YGS Open File 2008-3
Geochemical data from the Re-Analysis of a National Geochemical Reconnaissance stream sediment and water survey in the Finlayson Lake area of southeast Yukon Territory (NTS 105G)
Archived stream silt sediment samples collected in 1990 and originally published as GSC OF 1648 have undergone ICP-MS re-analysis producing data for an additional 35 variables. Site specific field observations and silt and water analytical data for 914 sites will be published.
GSC Open File 5694 - YGS Open File 2008-4
Geochemical data from the Re-Analysis of a National Geochemical Reconnaissance stream sediment and water survey in the Sheldon Lake area of east-central Yukon Territory (NTS 105J)
Archived stream silt sediment samples collected in 1990 and originally published as GSC OF 2173 have undergone ICP-MS re-analysis producing data for an additional 35 variables. Site specific field observations and silt and water analytical data for 886 sites will be published.
