Geology of Newfoundland and Labrador - Wikipedia
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 is the erosional remnant of an early Proterozoic geosyncline that formed by reactivation of an Archaean craton. Evolution of the geosyncline took place in seven phases: (1) development of a red-bed graben in the centre and south of the geosyncline; (2) slow subsidence and deposition of shelf sediments; (3) tectonic
