ABSTRACT
The Mississippian system along the borders of the Eastern Interior basin has been studied in considerable detail during the last 30 years but the results of most of this work have not yet been published. This paper briefly discusses the stratigraphy, paleontology, sedimentation, and structure and lists petroleum-bearing beds of the Mississippian system in Illinois, Indiana, western Kentucky, eastern Missouri, and southeastern Iowa as based on the published and unpublished investigations of more than 25 geologists and their numerous assistants, who worked mainly under the auspices of the various State geological surveys. Accompanying maps show the areal geology from Mercer County, Illinois, to Putnam County, Indiana, and include more than fifty 15-minute quadrangles which have been studied in detail.
