DetailsThe geology of the Labrador Trough is quite well known. Aided by exceptionally good outcrop, and stimulated by the presence of huge ore deposits, most of the trough has been mapped in great detail. Most stratigraphic correlations along and across the trough are very well established, particularly in the zone south of 57"30'N …
