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...

Flow pattern and related chemical quality of ground water in the "500-foot" sand in the Memphis area, Tennessee
Edwin Allen Bell, Dale J. Nyman
1968, Water Supply Paper 1853
The '500-foot' sand is the major source of water supply for the Memphis area. Thick layers of impervious clay above and below the sand confine the water in the aquifer under artesian pressure and also protect the aquifer from contamination. Recharge from rainfall enters the '500-foot' sand in the outcrop,...
