The
Adirondacks are located in northeastern New York, United States. The Adirondacks were accreted during the Shawinigan orogeny. This is evidenced by the deformation in the allochthonous monocyclic belt. The Highlands and Lowlands of the Adirondacks were separated before the Shawinigan orogeny. This

During the formation of the
Grenville Province, the type of tectonism changed. The earliest stages of formation were dominated by arrested subduction. The type of tectonism then changed to flat slab subduction. In the late stages of formation the tectonism changed to collisional orogenesis. Although

Makkovikia is located in eastern
Labrador. It was created during the Makkovik orogeny. An Andean-type arc developed and was accreted onto the preexisting continental rocks. Makkovikia's composition is rather complicated. The Kaipokok domain has both Archean crust and Paleoproterozoic volcanics and

During this time, deformation and metamorphism was widely spread throughout the entire
Grenville Province but the level of intensity varied. The exterior section of the province was subject to more deformation and metamorphism, while the interior was subject to more magmatism. The magmatism was

Ontario, Canada. It was an allochthon that was thrust up onto existing continental rock. The plutonic ages do not match surrounding rocks, which gives evidence of it being an exotic terrane. Algonquia's composition is orthogneiss, diorite, and quartz-dioritic orthogneiss. Its Nd model age is

The
Central Metasedimentary Boundary Thrust Zone makes up the northwestern boundary of the Central Metasedimentary Belt. It was created during the Shawinigan Orogeny (1.19-1.14 Ga). The Central Metasedimentary Belt is bordered to the south by Phanerozoic sedimentary rocks and

Grenville Province around 1.46-1.43 Ga, named the Michael-Shabogamo gabbros. From 1.42 to 1.35 Ga, there is no magmatic activity. After this period and until the end of the mid-Elsonian, the Nain Plutonic Suite is emplaced in Labrador.

In the northeastern central Metasedimentary Belt, the rocks are composed of Orthogneiss. The region is known as the Bondy and LaCoste domical complexes. In the southwestern Metasedimentary Belt, the rocks are tonalitic to granitic orthogneisses.

Morin is located near Ottawa, Canada. It was a terrane that was thrust up during the Shawinigan orogeny around 1.19-1.16 Ga. Its composition is Anorthosite-mangerite-charnockite-granite. Nd model ages of Morin are around 1.3-1.5 Ga.

Felsic magmatism dominates this time period. The cause of the magmatism is debated between an extensional setting or a continental-margin arc. The name is in relation to the ensuing orogeny and metamorphism.

Mixed compression and extension caused broad mafic magmatism during this time. This could be related to the Shawinigan orogeny which occurred in the southwestern region of the Grenville Province.
