Traverse of Upper Des Moines and Lower Missouri Series from Jackson County, Missouri, to Appanoose County, Iowa

This paper summarizes the stratigraphic results of a traverse of the Pennsylvanian upper Des Moines and lower Missouri series made along the strike from near Kansas City, Missouri, to Appanoose County, Iowa, an outcrop distance of 180 or 200 miles. The main objective of the traverse was the correlation of the heretofore unknown Iowa section of the Des Moines series with that of west-central Missouri. Standard names, long accepted in Missouri and Kansas, have been applied to the Iowa formations where this is possible. In addition, considerable new information concerning the stratigraphy of the Pennsylvanian of north-central Missouri is presented. Stratigraphic conclusions are presented in the form of eleven columnar sections, each composite for a selected area. The section are drawn to scale and show regional variations in lithology and thickness.
