Lithofacies and Depositional Environments

In the Panoma Field of southwest Kansas the Council Grove Group comprises seven fourth-order marine-nonmarine sequences. Through the detailed study of ten widely distributed and lengthy cores eight major lithofacies were identified and characterized (see Panel 2).

During Council Grove deposition, the Panoma Field area was situated on a broad shallow shelf or ramp that dipped gently southward into the Anadarko basin in Oklahoma. The geometry of the shelf was conducive for broad, parallel depositional environments and associated lithofacies belts. In response to cyclical sea level fluctuations, lithofacies belts migrated across the shelf resulting in a predictable vertical succession of the eight major lithofacies.
