AbstractRecent discoveries of basement-hosted uranium deposits, such as those of the Patterson Lake corridor along the southwestern margin of the Athabasca Basin, have underscored the potential of high-strain corridors within the south-west Rae Province as major fluid conduits. Although these buried basement domains have often been defined using airborne geophysical data, the paucity of regional geochronological information makes it difficult to relate the geo-physical signatures to the regional tectonothermal history. This report presents new zircon U-Pb Sensitive High-Resolution Ion Microprobe and biotite 40Ar/39Ar geochronological data for six samples that span the Taltson Domain of the southwest Rae Province. Three orthogneiss and one pegmatite sample from the Marguerite River area of north-ern Alberta crystallized at ca. 1.97 Ga and intruded 2.1 to 2.7 Ga crust, and biotite from a mylonitic shear zone yielded a ca. 1.82 Ga 40Ar/39Ar cooling age. Zircon cores from a sample of granitic gneiss sampled along the Clearwater River in northern Saskatchewan returned an imprecise crystallization age of 2422 ± 28 Ma (MSWD = 1.4), whereas recrystallized rims record granulite-facies metamorphism at 1923.0 ± 7.3 Ma.
Summary(Plain Language Summary, not published)
The Targeted Geoscience Initiative (TGI) is directed towards providing next generation knowledge and methods to facilitate more effective targeting of buried mineral deposits. The program aims to enhance the effectiveness of exploration for Canada¿s major mineral systems by resolving foundational geoscience problems that constrain the geological processes responsible for the liberation metals from their source region, transportation of these ore metals and control their eventual deposition. TGI supports projects on gold, Ni-Cr-PGE, porphyry-style mineralization, uranium and volcanic- and sedimentary-hosted base metal mineralization ore systems, with each project divided into subprojects focused on resolving specific knowledge gaps by integrating data and studies from multiple sites across Canada. Herein, we present interim results and interpretations from a selection of the research activities currently being conducted under the auspices of TGI.
