Acta ...Permian shales, sandstones, siltstones, limestones, sands, marls, and dolostones were deposited as a result of sea-level fluctuations. These fluctuation cycles can be seen in the rock layers. Relatively few sites lend themselves to direct radioactive dating, so the age of intermediate strata is often estimated.The Permian Sea. A great number of Kansas' physical features are the result of the Permian Sea. During the Permian Period, about 250-290 million years ago, the land of Kansas lay below an immense, yet shallow sea.
