GEOSCIENTIFIC REPORT SERIES

Geoscientific Report GR2021-2 coverGR2021-2

Geology of the Wuskwatim–Granville lakes corridor, Kisseynew domain, Manitoba (parts of NTS 63O, P, 64A–C)
by L.A. Murphy and H.V. Zwanzig
(94 p. plus accompanying Data Repository Item DRI2021014)

This report covers parts of two geological domains in the Paleoproterozoic Trans-Hudson orogen: the northeastern part of the Kisseynew domain (KD) and the south margin of the Leaf Rapids domain. The parts of the KD described in this report include the Kisseynew north flank and the Northeast Kisseynew subdomain. The bedrock of the north flank of the KD comprises abundant Paleoproterozoic, ca. 1.85–1.83 Ga metasedimentary rocks (the Burntwood group metaturbidite and the Sickle group subaerial to shallow-water metasandstone). Mineral showings along the Wuskwatim–Granville lakes transect have been considered, to date, as uneconomic but may be undervalued. A gold showing in sulphide-facies iron formation at the contact between Granville complex-type basalt/gabbro and the possible base of the Burntwood group, lies along a series of sulphide showings in shears that may represent a gold metallotect. Altered Granville complex basalt and ultramafic rocks feature elevated As, an element associated with Au. A glacial train of As anomalies and trace Au extends across the KD. A trace Cu showing on Notigi Lake may be related to stratiform copper mineralization that has been documented, also in the Sickle group, at Kadeniuk Lake, southwest of Granville Lake.

GEOSCIENTIFIC REPORT SERIES

Geoscientific Report GR2021-1 coverGR2021-1

Bedrock geology of the central Sipiwesk Lake area, Pikwitonei granulite domain, central Manitoba (part of NTS 63P4)
by C.G. Couëslan
(47 p. plus 1 appendix and 1 map at 1:20 000 scale)

A mapping campaign in the Pikwitonei granulite domain (PGD) of Manitoba was initiated in the summer of 2012 with work in the central Sipiwesk Lake area. Previous mapping in the area utilized descriptive petrography, and the majority of units were classified as either granofels (sic) or enderbites, which were further separated by the use of mineral-assemblage qualifiers (e.g., garnet-plagioclase-quartz-pyroxene±hornblende granofels and gneiss). One of the primary goals of the new mapping initiative was to remap the area and add protolith interpretation to define rock units. This was accomplished by integrating field observations with lithogeochemistry, isotope analyses and phase-equilibria modelling. However, interpretation of a protolith was not always possible because of the high metamorphic grade. It is hoped that an understanding of the origins of the gneisses that make up the PGD will lead to a better understanding of the domain and its relationship to adjacent domains and greenstone belts of the Superior province.

Bedrock topography of southern Manitoba
by G.R. Keller and G.L.D. Matile
(scale 1:1 000 000)

This map provides an overview of the bedrock topography at a regional scale. It was constructed using a combination of drillhole and geological mapping data originally plotted and interpreted by hand, modelled in GOCAD® software and subsequently interpolated in ArcGIS. This dataset represents the Manitoba Geological Survey's interpretation of the available data and was originally modelled from east-west–oriented cross-sections at a 5 km north-south spacing from the United States border to 54°N; no additional data has been added for this release. Additional background can be found in the map's surround.

This map provides an overview of the drift thickness at a regional scale. The drift thickness of southern Manitoba was calculated using the difference between interpreted bedrock topography and the Shuttle Radar Topography Mission 90 metre Digital Elevation Model. The bedrock topography of southern Manitoba was reconstructed using a combination of drillhole and geological mapping data originally plotted and interpreted by hand, modelled in GOCAD® software and subsequently interpolated in ArcGIS. This dataset represents the Manitoba Geological Survey's interpretation of the available data and was originally modelled from east-west–oriented cross-sections at a 5 km north-south spacing from the United States border to 54°N; no additional data has been added for this release.
