Abstract

When the present Iowa Geological Survey first began operations, 30 odd years ago, one of the surprising results connected with the determinations relating to the general stratigraphy of the State was a notable absence of Early Devonic sediments. The great magnitude and evident large diastrophic importance of this hiatus in sedimentation was naturally insufficiently regarded at the time; and early transference of personal activities to distant fields prevented further persuance of the theme.
