Detailed soil and till sampling, NTS 63K/16, central Manitoba, 1991.
(requires an Internet connection)
In 1991 as part of EXTECH-I, detailed soil and till sampling was carried out in the vicinity of the Chisel Lake, Ghost Lake and Lost Lake mines and the North Chisel deposit in central Manitoba. Approximately 144 sites were visited. Sample spacing averaged approximately 1 site per 200 m. At each site, samples of B-horizon glacial till (soil), C-horizon glacial till (parent material) and humus were collected. An interpretation of the study can be found in Geological Survey of Canada Bulletin 426.
The data are part of a compilation, Geological Survey of Canada Open File 7064.
Paper report, no data lists.
<0.002 mm fraction of B- and C-horizon till for 10 elements by AAS after aqua regia leach; for Hg and As by hydride generation AAS; for 31 elements by ICP-ES after aqua regia leach; for 7 elements by sequential extraction techniques.
<0.063 mm fraction of B- and C-horizon till for Au + 34 elements by INAA; for 31 elements by ICP-ES after aqua regia leach.
<0.177 mm fraction of humus for 31 elements by ICP-ES after aqua regia; the soluble organic fraction of humus for 7 elements after Na4P2O7 leach; the insoluble inorganic residue for 7 elements by sequential extraction techniques.
