Manitoba till-matrix geochemistry compilation: silt plus clay (<63 µm) size-fraction by inductively coupled plasma–mass spectrometry after an aqua-regia or modified aqua-regia digestion
by M.S. Gauthier
This GeoFile provides a digital dataset for till-geochemistry surveys carried out in Manitoba, where the silt plus clay (<63 μm) size-fraction of the till matrix was analyzed by inductively coupled plasma–mass spectrometry after an aqua-regia or modified aqua-regia digestion. This compilation of 35 projects includes 3554 till samples, and will be updated annually or bi-annually. This data can be brought into GIS software, and integrated with other geoscience data, to generate new exploration targets and design follow-up exploration programs.
This publication supersedes GeoFile 2-2022.
Note: GeoFile 2-2023 has been superseded by GeoFile 2-2024.

Updates to the Manitoba Mineral Deposits Database
by M.L. Rinne
The Mineral Deposits Database serves as the primary inventory of mineral occurrence data in Manitoba. This GeoFile contains the latest updates to the database, including recently compiled and revised mineral occurrence data for parts of the Superior province and all areas of Manitoba north of 57°N. In combination with other geoscientific data, these results can be used to inform mineral potential assessments, exploration targeting, or land-use planning.
This publication supersedes GeoFile 5-2022, and was superseded by GeoFile 5-2024.

Quaternary site data, till composition and ice-flow indicators in the Roseau River area, southeastern Manitoba (parts of NTS 62H2, 7)
by M.S. Gauthier and T.J. Hodder
The Roseau River area in southeastern Manitoba preserves an exceptional stratigraphic record of multiple Quaternary glacial-interglacial cycles. We examined 6 sections on the Roseau River, 4 gravel pits and 22 surface sites to document the surficial sediments and till composition. Released herein are the stratigraphic columns, till fabrics, till-clast lithology and till-matrix geochemical data.

Metamorphic map of the Flin Flon domain, west-central Manitoba (parts of NTS 63J, K, N, O)
by M. Lazzarotto, D.R.M. Pattison, S. Gagné and C.G. Couëslan
This report outlines early contact metamorphism and later regional metamorphism in the Flin Flon domain of Manitoba and Saskatchewan. Regional metamorphic isograds and zones are described for both mafic metavolcanic rocks and metasedimentary rocks, and local metamorphic conditions are estimated using thermodynamic phase-equilibrium modelling. An accompanying map outlines metamorphic mineral assemblages, mineral isograds, and metamorphic zones for the Flin Flon domain.

Age and petrology of zirconium- and light rare-earth element–enriched quartz monzonite in drillcore from the Huzyk Creek property, sub-Phanerozoic Kisseynew domain, central Manitoba (NTS 63J6)
by C.G. Couëslan
This report investigates granitoid and metasomatic rocks enriched in Ba, Sr, light rare-earth elements (LREE) and Zr that were discovered in drillcore while researching a vanadium-enriched graphite deposit on the Huzyk Creek property. The rocks occur within metamorphosed greywackes and mafic rocks of the Kisseynew domain, which are buried under Phanerozoic sandstone and limestone. The granitoids are likely related to similarly enriched rocks in the Trans-Hudson orogen of Manitoba that have been explored for U, Th, REE and P, which can also be associated with carbonatite magmatism.

Indicator mineral and gold grain data from till sampled in the Churchill to Little Churchill rivers area, northeastern Manitoba
by T.J. Hodder and M.S. Gauthier
The Manitoba Geological Survey conducted a till indicator mineral and gold grain count survey in the Churchill to Little Churchill rivers area in 2021. This report releases the visible gold grain and indicator mineral (magmatic or metamorphosed massive-sulphide–indicator minerals) and kimberlite-indicator minerals count data, and provides a preliminary interpretation of the ice-flow direction(s) that deposited the sampled tills. These results are being released before the comprehensive data report to provide the mineral exploration industry timely updates on new geological knowledge.

Progress report on the study of granitoids in Manitoba: petrogenesis and metallogeny
by X.M. Yang
This report presents petrological and geochemical characteristics of diverse granitoid rocks in 48 intrusions emplaced into various domains (belts) in parts of the western Superior province and Trans-Hudson orogen within Manitoba, and investigates their geodynamic settings, petrogenesis and mineral potential. The major findings of this study are that muscovite- and/or garnet-bearing S-type granitic rocks characterized by low MS values (<0.1 × 10-3 SI unit), ferroan, calcalkaline and strongly peraluminous affinities intruded exclusively into and/or occurred close to collisional (or terrane/domain boundary) zones, which were associated genetically with critical metals (e.g., Li, Ta, Cs, Nb, Be)–enriched pegmatite intrusions. In addition, this report is accompanied by Data Repository Item DRI2022012 and a GIS-based database containing information about the UTM coordinates, field relationship, tectonic unit, petrography, lithogeochemistry and available U-Pb zircon geochronology of 323 granitoid samples collected from these granitoid intrusions.
This publication also includes:
- ArcGIS shapefiles of the geochemical data
- Data Repository Item DRI2022012: Whole-rock geochemical and Sm-Nd isotopic data of granitoid rocks from Manitoba (parts of NTS 52E, 52L, 52M, 62I, 62P, 63J, 63P, 64A, 64B, 64C, 64F)
