Relation of the Ozark uplift and deposition of the Cherokee Group (Middle Pennsylvanian) sediments in eastern Kansas
- Kansas Geological Survey, Lawrence, KS (United States)
The Cherokee Group of Middle Pennsylvanian age, as defined in Kansas represents the earliest deposits in eastern Kansas of Pennsylvanian rocks overlying carbonate rocks of Mississippian age. Cherokee rocks consist primarily of shales, with abundant siltstones and sandstones, numerous thin but persistent coal beds, and a few thin limestones. In Kansas, the area of thickest deposits of Cherokee rocks is in the Forest City basin where its thickness exceeds 800 feet (250m). In the Kansas portion of the Cherokee basin thickness of the Cherokee Group reaches a maximum of 550+ feet (170m). Influence of the Ozark uplift on deposition patterns of the Cherokee in Kansas is suggested by some of the sandstone patterns in the lower and middle portion of the group. A possible relation of the Bourbon arch area to structural features in Missouri, has also influenced Cherokee deposition. Based on the widespread distribution of the lowermost prominent coal bed, the earlier deposits of the Cherokee Group in the Forest City basin essentially terminate against the Bourbon arch, and do not continue southward into the Cherokee basin. Good correlations are possible in the upper part of the Cherokee Group across eastern Kansas. Correlations are mainly possible due to widespread radioactive shales and persistent coal beds. Correlations in the middle and lower part of the group are more difficult as they are carried northward across the Bourbon arch into the Forest City basin. Several lower coal beds in the group including the Riverton coal appear to be persistent and allow tentative correlations.
