...M.E. Bickford; T.D. Mock; W.E. Steinhart, III; K.D. Collerson; J.F. Lewry Abstract U–Pb zircon ages from the exposed Sask craton are 2450–3100 Ma, from the Peter Lake Domain 2575–2640 Ma, and from rocks of the Trans-Hudson orogen 1840–1880 Ma. U–Pb monazite and zircon ages of post-orogenic...

... collision and underplating of the Flin Flon – Glennie Complex by the Archean Sask Craton during prolonged protocontinent–continent collision over a minimum 1826–1805 Ma interval. 1 This article is one of a selection of papers published in this Special Issue on The Trans-Hudson Orogen Transect...

...N.M. Rayner; R.A. Stern; M.E. Bickford Abstract This study reports new sensitive high-resolution ion microprobe (SHRIMP) and thermal ionization mass spectrometry (TIMS) U–Pb geochronological data for thirteen rocks from the Archean to Paleoproterozic Sask Craton, the Peter Lake Domain and Hearne...

... of existing seismic reflection information, is presented. The seismic images identify the regional geometry of the basal detachment zone (Pelican thrust) that separates juvenile allochthonous terranes from the underlying Archean microcontinent (Sask craton). The Sask Craton is inferred to have a minimum...

...K E Ashton; L M Heaman; J F Lewry; R P Hartlaub; R Shi Abstract The largely buried Sask Craton is a continental fragment or microcontinent that collided with and underthrust the Paleoproterozoic Flin Flon - Glennie protocontinent along the Pelican Décollement Zone at 1840-1830 Ma. Rocks of the Sask...

...K.E. Rubingh; B. Lafrance; H.L. Gibson The Snow Lake gold camp is located within amphibolite facies volcanic rocks of the ca. 1.88–1.87 Ga Flin Flon – Glennie Complex (FFGC) in the Trans-Hudson Orogen, Manitoba. During thrusting and collision with the Archean Sask craton, volcanic rocks were...

..., and diamond-bearing roots in unusually rich detail for cratonic settings such as those of the Superior and Slave cratons, as well as pericratonic (shield) settings such as those of the Sask craton and Buffalo Hills terrane. The Superior and Slave examples of craton construction by multiple underthrust layers...

... allocthonous Paleoproterozoic juvenile terranes and arc rocks of the western Trans-Hudson orogen have been juxtaposed against the Archean Sask craton. Impedance tensor decomposition of data from the 40 MT sites in the area indicates a geoelectric strike of N28°E. Two-dimensional inversion of the data using...

... studies to the north define conductors on the margin of the Sask craton. The results suggest the TOBE conductor is associated with the Sask craton margin. The MT results indicate significant along-strike variation of the SBZ in southern Manitoba. * 705-521-5646 705-682-8243 evangowan...

... that at least some source material for the granitic magmas included earliest Paleoproterozoic crust (Sask Craton?), or its derived sediments, and that Rottenstone granitic magmatism postdated plutonism in the bounding La Ronge Arc and Wathaman Batholith. We estimate the age of terminal metamorphism in the Davin...
