Labrador is part of the eastern Canadian Shield and intrusive igneous or metamorphic rocks are the most common, with sedimentary rocks in some areas. Four of the seven Canadian Shield provinces make up Labrador. Archean age rocks and east-west structural trends mark the Superior Province (a small area in the west near Quebec) which encompasses the Ashuanipi Complex granulite and granodiorite intruded by pyroxene-rich felsic plutons. The Nain Province runs along t
The Labrador Trough contains world-class iron deposits which have been mined since 1954. The direct shipping of Knob Lake ores were mined at Schefferville from 1954 to 1982. Concentrate production began in 1961 in the southwest end of the Trough, with three mines currently producing concentrate and pellets at a rate of 35 Mt per year.
The geology of the eastern margin of the Labrador Trough is comprised of a series of 14DPaleoproterozoic (2.17 to 1.87 Ga) sedimentary and volcanic rocks, which have been subdivided into a series of distinct lithotectonic zones. Numerous mineral occurrences are known in this region, which include the following deposit types:
The western half of the Labrador Trough, consisting of a thick sedimentary sequence, can be divided into three sections based on changes in lithology and metamorphism (North, Central and South). The Trough is comprised of a sequence of Proterozoic sedimentary rocks including iron formation, volcanic rocks and mafic intrusions known as the ...

Jan 01, 2021 The Labrador Trough (or New Québec Orogen) is a NNW-SSE oriented fold-and-thrust belt, primarily composed of Archaean to Palaeoproterozoic volcanic and metasedimentary rocks (Hoffman, 1990, Henrique-Pinto et al., 2019). Pervasive westward imbricate thrusting occurred during oblique collision between the Superior and Southern Rae craton at 1.84 ...

The siliciclastic Wishart Formation of the Early Proterozoic Labrador trough is a high‐energy shelf deposit. Wishart sandstones contain both interstitial chert with textures of void‐filling cement and thin chert intercalations contaminated with siliciclastic mud. Although volumetrically minor, these cherts occur in several thin, areally ...
Labrador Trough The Labrador Trough is mostly recognized for its extensive iron formations, toting more than 80 billion tonnes of iron ore resources. The deposits consist of altered and metamorphosed bands of iron and chert, which originally draped over a seafloor some 2.3 billion years ago.

Labrador The geology of Labrador is much older than Newfoundland, with rocks dating back to 4 billion years — some of the oldest on earth. Exploration in Labrador has mostly focused on three areas: the Labrador Trough in western Labrador, the Central Mineral Belt near the region’s midline on the eastern coast and around Vale ’s (NYSE ...
Our conclusions receive additional support from a number of examples where Fe(II)-silicate minerals have precipitated in close association with Ca-phosphate; for instance, the Paleoproterozoic Sokoman Iron Formation of the Labrador Trough, eastern Canada (Pufahl et al., 2014), and Ordovician oolitic ironstones of Bell Island, Newfoundland ...
"The Eldor carbonatite complex, located in the Labrador Trough region of Quebec, Canada, is a relatively unstudied deposit. The complex has a ubiquitos distribution of pyrochlore throughout the units, contains REE mineralization in the form of monazite and contains several minerals which would be economically viable as a by-product of pyrochlore mining. The units identified in this study, at ...
