Multiple Metals: NE Manitoba
The scientific research and results of this project are available via GEOSCAN.
The Multiple Metals: NE Manitoba project, part of the Geo-mapping for Energy and Minerals (GEM) program, will produce an updated and integrated bedrock and surficial geological knowledge base for far northern Manitoba.
Project leader – Janet Campbell
Hypothesis:
How do supracrustal sequences in northern Manitoba correlate with better known packages in Nunavut, and can better understanding of the region’s glacial history help to reveal its metallogenic potential?
Research objectives include:
- distinguishing Archean and Proterozoic sequences and evaluate their metallogenic potential for gold, copper, base metals, PGEs, rare elements, diamonds, and uranium, through mapping, geochronology, high-resolution geophysical surveys and correlation with better known rock packages in Nunavut;
- improving drift prospecting methods in this largely drift-covered area through regional and targeted surficial mapping, till and lake sediment geochemistry; and
- contributing to understanding the origin of enigmatic Rogen moraine terrain through landform mapping and analysis.
Scientific Highlights
- 5 separate supracrustal sequences (2.7, 2.4, 2.0, 1.9, 1.8 Ga) have distinct metallogenic potential (VMS, gold, Cu-Ni-PGEs).
- Lake sediment and till geochemical maps reveal metal dispersal patterns.
- Ice-flow indicator and landform mapping reveals a complex glacial history and a fragmented glacial landscape stressing the importance of understanding both the regional and local setting.
- Rogen moraine were likely formed under active ice conditions from pre-existing till rather than by deposition of new sediment related to the younger ice flow; associated dispersal patterns are likely related to both flows.
