摘要：

Increments of Peoria Loess having unique mineralogy, associated with changes in loess source sediments, are used to establish the nature of loess distribution from the Illinois River Valley in west-central Illinois. Dominance of the latest loess increments suggests that most of the parent loess along the Illionois soil maturity sequence is relatively young. Variations in degree of soil development along the sequence cannot be attributed solely to age differences.
