Quick Summary

The Labrador Trough is a geological region in western Labrador, Canada, characterized by softer sedimentary deposits within the ancient rocks of the Canadian Shield. This area is significant for containing some of North America's most extensive iron-ore deposits.1

The Labrador Trough is part of the larger geological province of the Canadian Shield, which is composed of some of the world's oldest rocks. While the shield is primarily igneous and metamorphic, the trough features sedimentary layers. The region's landscape is marked by numerous lakes and rivers, and its coastline is deeply indented with fjords and islands. The area has been significantly shaped by continental glaciation during the Pleistocene Epoch.12
