Sebastian Tappe,Sebastian Tappe,George A. Jenner,Stephen F. Foley,Larry M. Heaman,Dean Besserer,Bruce A. Kjarsgaard,Bruce Ryan +7 more
TL;DR: The Torngat ultramafic lamprophyres have a Neoproterozoic age and are spatially and compositionally closely related with the Neoprophenozoic ultramerafic lamps from central West Greenland as mentioned in this paper.

The Nain-Churchill Boundary and the Nain Plutonic Suite: A Regional Perspective on the Geologic Setting of the Voisey’s Bay Ni-Cu-Co Deposit
TL;DR: The Nain-Churchill boundary has been interpreted as a transcrustal conduit that allowed the Voisey's Bay mafic intrusions rapid transit from their mantle staging area as mentioned in this paper.

The Makkovik Province: extension of the Ketilidian Mobile Belt in mainland North America
TL;DR: In the Aillik and Cape Harrison domains, highgrade supracrustal rocks of similar aspect to those of the Kaipokok Domain are separated from the basement by mylonite zones, in a thick-skinned fold-and-thrust belt (Kaipokk Bay Structural Zone), believed to record significant northwest-directed translation.

New reflections on the structure and evolution of the Makkovikian ‐ Ketilidian Orogen in Labrador and southern Greenland
TL;DR: Marine seismic reflection profiles across the Early Proterozoic Makkovikian - Ketilidian Orogen in the Labrador Sea region suggest that it is a doubly vergent, asymmetric orogenic belt, comparable in width to younger collisional orogens as discussed by the authors.
The boundary between Proterozoic and Archaean crustal blocks in central West Greenland and northern Labrador
TL;DR: In this paper, the contact between the Early Proterozoic Nagssugtoqidian Mobile Belt and the Archaean craton in West Greenland, and that between the Churchill Province and the Nain craton of Northern Labrador represent two cross-sections of an Early Propperozoic orogenic boundary.
