  • The clay mineralogy of three pre-Woodfordian tills of the Grand River lobe in Columbiana County, Ohio, shows the influence of the underlying Pennsylvanian strata of the Allegheny Plateau. The mean diffraction intensity ratios (DI) of these sandy tills range from 0.5 to 0.7. These ratios are comparable to those of the underlying bedrock; 60% of the variance of the clay mineralogy may be attributed to the bedrock. Weathered bedrock and weathered older drift are possible sources of kaolinite… CONTINUE READING
