  • Tectonic History of the Southwestern Margin of the Rae Province in Northwestern Saskatchewan
    Tectonic History of the Southwestern Margin of the Rae Province in Northwestern Saskatchewan K.E. Ashton* and C.D.

Hartlaub, Department of Mining Technology, British Columbia Institute of Technology, Burnaby, BC V5G 3H2; K.M.

Rayner, Natural Resources Canada, Geological Survey of Canada, 601 Booth Street, Ottawa, ON K1A 0E8 Summary The southwestern Rae margin in northwestern Saskatchewan includes 3.01-2.94 Ga and 2.62- 2.58 Ga granitoids typical of the Rae Province. The Arrowsmith Orogen produced 2.37 Ga metamorphism and 2.33-2.30 Ga post-collisional granitoid rocks. Initial deposition of the Murmac Bay group at about 2.33 Ga was derived from an unknown Paleo- to Mesoarchean source; higher stratigraphic levels record diverse locally exposed rocks and a 2.2-2.0 Ga suite possibly exposed to the west. Multiple terrane accretions during the Taltson Orogen produced a 1.94-1.92 Ga southeast-striking regional foliation, which was overprinted by a 1.91-1.90 Ga northeast-striking fabric associated with tectonism along the Snowbird Tectonic Zone. Circa 1.84-1.83 Ga terrane accretion farther west and terminal collision in the Trans-Hudson Orogen resulted in widespread faulting, deposition of the Martin Group, and the historic Beaverlodge uranium and gold deposits. Abstract Integration of data from the southwestern margin of the Rae Province in Saskatchewan and the Taltson Magmatic Zone to the west is shedding more light on the region’s tectonic history.

Characterizing the accompanying tectonic processes during this time has been complicated due to polymetamorphism, which results in the obscuring of the age record of the terranes involved. To improve the knowledge of the tectonic evolution of the South Rae Craton, petrologic and structural analyses are applied in conjunction with in situ trace element chemistry, inclusion barometry, U-Pb monazite and titanite, and Lu-Hf garnet chronology.

Dedication For Tawny Abstract The Queen Maud block is divided into two crustal belts. The western Perry River belt is dominated by Mesoarchean to Neoarchean granitic gneisses and supracrustal rocks; it was incorporated into the Rae domain by at least 2.46 Ga. The eastern Paalliq belt is dominated by the 2.52-2.45 Ga Queen Maud granitoids and the 2.45-2.39 Ga Sherman supracrustal sequence, both of which were formed on Neoarchean crust of the Rae domain. Slave-Churchill collision and convergence occurred ca. 2.43-2.35 Ga resulting in granulite-facies metamorphism, regional scale N-S trending strike-slip shearing, and minor crustal melting in the Queen Maud block.

Heaman a, R.A. Creaser a, K.E. Ashton b, A. Simonetti a a Department of Earth and Atmospheric Sciences, University of Alberta, 1-26 ESB, Edmonton, AB, Canada T6G 2E3 b Saskatchewan Geological Survey, 2101 Scarth Street, Regina, SK, Canada S4P 3V7 Received 22 October 2004; received in revised form 18 August 2005; accepted 1 September 2005 Abstract New Sm–Nd and U–Pb data indicate that a block of ancient Mesoarchean and Paleoarchean crust (3.0–3.9 Ga) is present along the southwestern margin of the Rae Province, Canada. Consequently, the Rae Province can be divided into an ancient (>3.0 Ga) southwestern component and a more juvenile (<3.0 Ga) northeastern component. Evidence for episodic reworking of the evolved southwestern component is recorded in the Sm–Nd and U–Pb signatures of younger Archean and Paleoproterozoic intrusive rocks and sediments. Nd model ages range from 2.7 to 3.3 Ga, with the oldest signatures occurring along the western end of the Beaverlodge Belt, Saskatchewan. Xenocrystic zircons with ages of ca. 2.3, 3.0, 3.2–3.3 and >3.6 Ga were discovered in two Paleoproterozoic granites. © 2005 Elsevier B.V. All rights reserved.

  • The Role of the Global Arrowsmith Orogeny and Its Impact in Western Canada
    Pre-Nuna supercontinent reconstruction: the role of the global Arrowsmith Orogeny and its impact in western Canada S. J. Pehrsson* ([email protected]) and R. G. Berman, Qui, Haijun1, Davis, W.J., Ryan, J.2 Geological Survey of Canada, 615 Booth St., Ottawa, ON K1A 0E9 1 Strategic Research Center of Oil & Gas Resources, Ministry of Land & Resources, China 2 Geological Survey of Canada, 625 Robson St.Vancouver, BC V6B 5J3 Introduction The great interest in supercontinent reconstructions reflects the importance of the supercontinent cycle in understanding global plate tectonic processes and its influence on formation and preservation of ore deposits. In spite of the substantive progress that has been made in reconstructing Earth’s younger supercontinents (e.g. Rodinia, Gondwana, Pangea), the number and possible makeup of supercontinents prior to the first known supercontinent Nuna, at 1.8 Ga, remain poorly understood. Traditionally the western Churchill Province (wCP,) was thought to have been part of Kenorland, a single supercontinent that amalgamated pre-2.6 Ga, was stable ca. 2.5 – 2.1 Ga and broke up by 2.1 Ga . The recent identification of the. 2.5 – 2.3 Ga Arrowsmith orogen on the western flank of the wCP (Berman et al., 2005) offers a very different picture for what has been considered a quiescent period, possibly linked to a plate tectonic shutdown on Earth (Condie et al., 2009). Here we present new geochronological data that provide important support for a broader distribution of the Arrowsmith orogen and review its possible global extent. Global recognition of this relatively uncommon period of orogenesis apparently negates the tectonic shutdown hypothesis and will provide a useful piercing point to explore pre-Nuna supercontinent reconstructions.
