Sedimentology and Structure of Terrestrial to Shallow Marine Outcrops of the Pennsylvanian Mingus Formation, Mineral Wells, Texas

| Field Trip Description: Pennsylvanian shelf and non-marine clastic depositional systems are well exposed in several cliff sections around Mineral Wells, Texas. We will examine the entire spectrum of terrestrial to shelf clastic environments including; gravelly fluvial deposits at Mineral Wells State Park, an incised valley deposit in the town of Mineral Wells and wave-dominated shoreface deposits near Wizard Wells. Much of the focus of the trip will be on spectacular examples of normal and growth faulted strata within fluvial-dominated delta front sandstones near Bennett, Texas. These are potentially analogous to the more regional-scale growth faults that are big producers in the Gulf Coast. These faults can also introduce significant heterogeneity in subsurface analogs and we will discuss the effective properties of the faults as conduits and seals. Several stops are excellent locales for collecting fossil plants and marine invertebrates. |
