Comments:Digital magnetic and radiometric data from adjacent, and often overlapping, high-resolution surveys flown by mineral exploration companies within Labrador’s Central Mineral Belt were mutually levelled and merged in this compilation (see survey index, located on the margin of each PDF map).  The composite magnetic results were subsequently merged with regional aeromagnetic data, available from the Geological Survey of Canada’s Geophysical Data Repository.
