... craton to the east (Churchill Province), and defines an eastward-thickening miogeocline. The Labrador Trough sequence (Kaniapiskau Supergroup) consists of two distinct depositional cycles of sediment and volcanic deposition. An erosional unconformity and a possible episode of tectonic disturbance divide...

..., the Kaniapiskau Supergroup can be divided into four terrigenous lithotypes metamorphosed at low-grade: one set with greater compositional and textural sedimentary maturity classified as quartz arenites and subarkoses, and another set with lower textural maturity classified as feldspathic wackes and mudrocks...

...) rocks of the Kaniapiskau Supergroup of the Labrador trough were deposited. South of the Grenville front, the supracrustal sequence and the Archean basement were later polyphase deformed and metamorphosed, mainly at the amphibolite-facies level, during the Hudsonian orogeny (1,640 to 1,830 m.y. B.P...

... such a methanogenesis and post-depositional alteration ( Qu et al. 2012 ; Weber and Gauthier-Lafaye 2013 ; Črne et al. 2014 ; Kreitsmann et al. 2019 ). The stratigraphy of the Labrador Trough, formally comprising the Kaniapiskau Supergroup, is divided into numerous groups (Seward, Pistolet, Swampy Bay...

... of the Kaniapiskau Supergroup, which unconformably overlie the Archean basement gneisses and intrusives. The Attikamagen slates and shales form the lowest member, which thins out to the west, and the overlying quartzite rests on these basement rocks. The Denault dolomite is a distinctive buff-colored weathered rock...

...Michael A. Hamilton; Kenneth L. Buchan Abstract Otish Gabbro sills intrude sedimentary rocks in the Otish Basin of the southeastern Superior Province. Here, deposition of Otish Supergroup sediments had previously been thought to be older than K–Ar and Sm–Nd ages of ca. 1750–1710 Ma for Otish Gabbro...

... the early Paleoproterozoic Kaniapiskau Supergroup in western Labrador and adjacent Quebec, and Archean and Paleoproterozoic rocks extending southward into the Grenvillian parautochthon from the eastern Churchill and Makkovik provinces. The granitoid orthogneiss (with minor metasedimentary gneiss) occur...
