Seismic Reconnaissance of Lake Melville, Labrador
Seismic profiler transects indicate that much of Lake Melville is underlain by sedimentary strata, which are probably an extension of the (Proterozoic? Paleozoic?) Double Mer Formation, exposed onshore to the northwest. The southeastern limit of these strata in Lake Melville is inferred to lie benea...
