Laboratory and field studies of the Kibbey formation indicate that Kibbey rocks were deposited largely in shallow, marine, oxidizing water in the Big Snowy sea which extended across central Montana during late Mississippian time. The climate was semi-arid. Relatively stable tectonic conditions with moderate to low relief prevailed in the source area throughout Kibbey deposition. The present northern limit of Kibbey rocks is a result of post-Kibbey erosion; the southern limit, although locally determined by erosion, is essentially the depositional limit. Sandstone beds of the Kibbey produce oil in Musselshell and McCone Counties, and produced for a short time in Roosevelt County, Montana. Kibbey rocks at all 3 productive localities appear to have been deposited under very similar environmental conditions and in essentially the same position with respect to the axis of the Big Snowy sea.
