H. Edward Clifton
1968, Circular 587
Local concentrations of gold have been identified in surface sediments on the continental shelf off southern Oregon between Cape Arago and Cape Sebastian, a distance of about 40 miles.

Application of ultraviolet reflectance and stimulated luminescence to the remote detection of natural materials
William R. Hemphill
1968, Open-File Report 68-126
Carbonate rocks and evaporite deposits commonly exhibit relatively high reflectance in the ultraviolet (<3600A), and some outcrops of these materials are selectively shown on ultraviolet imagery. Other materials which are commonly strongly imaged on ultraviolet imagery and photography include water, snow, concrete, and metallic objects, particularly aluminum.Outdoor tests of an...
