Abstract
Terranes older than those of Paleozoic age occupy in Iowa a very small area. Attention which has been bestowed upon them is about commensurate with their relative surface extent. Heretofore, little attempt has been made to determine their broader stratigraphic relationships, their real position in the general geological column, their possible subdivision, or their role in the geotectonics of the region. It has seemed all sufficient to merely note their existence in the extreme northwest corner of the state. Yet, these very rocks now appear to have a history longer, more complicated and more vicissitudinous than any other terrane represented within our borders.
