Survey Description
In 1996, humus, soil, till, vegetation and rocks were collected in east central Manitoba as part of Operation Superior. Samples were collected in the Carrot River, Munro Lake and Echimamish River greenstone belts on approximately 1 km centres or as dictated by access to landing sites using a float equipped helicopter. A till pit was hand augered at each site and all other samples were collected in and around the immediate area of the till pit.
Approximately 317 humus samples were collected from beneath the moss mat that was normally removed prior to digging the till sample pit. If the humus layer was too thin, the sample site was moved 5-10 m away from the till pit. Care was taken to avoid any inorganic material. Duplicate samples were collected at approximately every tenth site.
Approximately 321 B-horizon soil samples were collected from the same till pit. The B-horizon was isolated on a clean face of one or more walls of the pit and then scooped into a sample bag. Care was taken not to include any organic material. Duplicate samples were collected at every tenth site.
Approximately 256 till samples were collected from hand-dug pits which were dug to a maximum depth of about 1 m, or until bedrock or the first unoxidized C-horizon till was intersected. A half kilogram of relatively unoxidized till was collected for geochemical analyses and an 11 L pail of till was collected for diamond indicator mineral processing. Duplicate samples were collected at approximately every fifteenth site in a new till pit.
Between June and August 1997, black spruce bark and twigs were collected. At most sites, the vegetation was collected within 20 m of the till pit. Approximately 60 g of loose outer bark was collected and inner bark was avoided. The twigs were collected from the upper 45 cm of the tree.
Outcrop rock chip samples were collected after moss mats and soil were removed from the outcrop. A representative sample consisted of 3-4 fist-sized chips.
The data are published in Manitoba Energy and Mines Open Files OF97-2 and OF97-1 (Max Lake).
Kimberlite indicator mineral (KIM) data are also available in Manitoba Geological Survey Open File Report OF2002-1.
The data are also part of two compilations in Manitoba Agriculture and Resource Development open files OF2020-2 and OF2020-5.
Data Description:
Paper report, data on diskettes.
Quantities Analysed:
<0.180 mm fraction of humus was analyzed by ICP-AES after a four-acid total digestion and by INAA for suites of elements. <0.180 fraction of B-horizon samples was analyzed by ICP-AES after a four-acid total digestion and by INAA. <0.250 mm fraction of B-horizon samples were analyzed by enzyme leach-ICP-MS analysis. <0.002 mm fraction of till was analyzed by ICP-AES after an aqua regia digestion for 34 elements and for As by hydride generation and for Hg by CV-AAS. <0.063 mm fraction was analyzed by INAA for Au and 34 other elements. Ashed vegetation samples were analysed by ICP-AES after an aqua regia dissolution and by INAA.
Geochem Maps Available:
