Abstract
Cooperative reconnaissance studies have not only verified earlier reports of high concentrations of heavy minerals in surficial sediment on the continental shelf but have also identified additional mineralized areas. A total of 222 large-volume (average of 201bs) core and grab samples from the entire Atlantic coastline of Virginia were analyzed. Concentrations of one or more economic minerals from 41 offshore samples equalled or exceeded typical values of economic deposits on land. Two regions (offshore of Smith Island and False Cape) with multiple samples and several areas with isolated samples have economic potential based on concentrations of total heavy minerals, monazite, zircon, and titanium-bearing minerals (ilmenite, leucoxene and rutile).
