Wolfcampian Series, Depositional sequences, Fusulinid facies
The Wolfcampian Series crops out along the base of the Glass Mountains escarpment (King, 1930, 1937) and, in the western part of the Marathon Basin, in folded and faulted beds exposed in the Dugout structural fold belt, the westernmost belt in the Marathon Orogen (Ross, 1963). The Wolfcampian is divided into two stages, a lower Nealian Stage and an upper Lenoxian Stage (Ross and Ross, 1987a, 1987b). Strata of these two stages are separated by a major tectonic event in the history of the Marathon orogeny and, as a result, by a major angular unconformity that separates the structurally deformed strata of the Nealian from the slightly deformed Lenoxian strata that crop out nearly continuously as a band across the base of the Glass Mountains escarpment.
