Abstract

Applying sequence stratigraphy methods to the Tyler Formation (Mississippian-Pennsylvanian) can yield valuable data about Tyler geological history. The Tyler Formation has 14 facies across that are consistent across the Dickinson Field, Stark County, North Dakota. The Upper Tyler is a marine dominated environment with large limestone and black shale deposits with an overlying smaller terrestrial deposit capped by a paleosol. The Upper Tyler records a single sea level rise and fall cycle. The Lower Tyler is a deltaic environment with several sandstone deposits. The Lower Tyler has 3 paleosols overlying a coarsening upward pattern of marine shales to nearshore and channel sands. The Lower Tyler records at least two sequence boundaries. Sequence boundaries are consistent across the field and are a possible surface to correlate across the basin.
