New investigations of the Morrison Formation with inside the western Oklahoma pan handle display that the formation is about 60 m thick close to Kenton, appreciably much less than ancient measurements. We offer a brand new isopach map of the Morrison Formation on the basin margin and divide the formation into 3 new individuals primarily based totally on geological, geochemical, petrographic, and paleontological characteristics. Each member is described through precise depositional facies recording a variable climatic sign and the eventual progradation of the distributive fluvial machine to the basin margin. Analogous depositional facies and lithology’s of those gadgets advocate they're lateral facies successions of the well-installed individuals of the Colorado Plateau. The Cimarron Member consists of several small, ephemeral, clastic lakes on the distal margin of the alluvial braid undeniable of the Tidwell Member. The Boise Member includes several perennial limestone lakes on the distal fringe of the Salt Wash Member distributive fluvial machine.
