Abstract : The study was conducted in terrain covered with glacial debris to determine the value of gravity measurements in the search for gravel deposits. The area used was a part of Ohio where there was considerable data available on the character of the glacial cover and the bedrock surface beneath. A residual gravity map was calculated for the area using 750 field stations. This map was compared to existing bedrock maps. The gravity low was over the Teays River Valley. Seismic refraction verified these conclusions and defined the shape of this preglacial valley. Two-dimensional gravity model studies were then conducted to determine if the lows within the major low were caused by high concentrations of gravel. The model studies suggest strongly that gravel is related to the greatest lows. (Modified author abstract)
