The subject of this paper is the correlation of thermal imagery with subsurface gravel deposits in vegetated areas where some ground surface is exposed. Geologic history was reviewed to select potential areas of study. An overflight was made using a thermal multispectral scanner. The data are processed with a computerized system to delineate areas showing a quartz spectral signature radiated from the ground surface. These areas were them compared with exploratory drill-hole data and found to correlate in every location where drilling had located substantial subsurface gravel. The correlation was noted during a search for gravel on national forest land in Louisiana. Processed data from an airborne scanner were compared with exploratory drill-hole logs. The correlation was noted at eight widely dispersed locations of subsurface gravel deposits. Areas without subsurface gravel showed negative correlation. It was concluded that more time and effort are needed to verify the usefulness of the correlation for locating new gravel pits.
