Abstract

Iowa geologists have long experienced great difficulty in isolating good key beds in the younger Pennsylvanian strata. This difficulty is due to the cyclothemic nature of the sediments. The marked success of the Missouri Geological Survey in distinguishing southward extensions of these strata in Missouri on the basis of their insoluble residues has led to a similar attempt in Iowa.
