Aspects of Catenary and Depth Distribution of Opal Phytoliths in Illinois Soils1
- Robert L. Jones and
- A. H. Beavers2
Soil opal phytolith content is intimately related to internal soil drainage; highest opal contents occur in the middle of the drainage sequence. Soil productivity is invoked to explain the catenary opal distribution. Phytoliths are concentrated in the surface horizon of Planosols but distributed downward to 20 inches in Brunizem and Gray-Brown Podzolic soils. Differences in chemical and catenary milieu, soil fauna, or loess depositional pattern are possible causes for depth distribution differences.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
