Abstract
The chemical and mineralogical relationships between three closely associated parent materials and the solum overlying each of them were studied. Methods common in soils research were employed. Curdsville limestone, Fairmount limestone, and Garrard siltstone formations were located in Garrard County, Kentucky. Profiles of Maury, Kenton, and Lowell soil series, locally associated with these formations, respectively, were sampled down to bedrock. The top 12 inches of bedrock was also sampled. Petrographic study indicated weathering of glauconite in the sand and silt fractions as the solum surface was approached. Likewise, a 10Å. component of the clay fraction, presumably glauconitic, decreased in abundance in the more weathered upper solum while vermiculite and other 2:1 expansible layer silicates became more abundant. Kaolinite also was more abundant in the upper solum.
