Quizplus · Accepted Answer

The erosional surface on the top of the Muav Limestone represents a period of non-deposition and erosion which separates the Muav Limestone from the overlying Temple Butte Formation. This is a type of unconformity known as a disconformity. The other options can be ruled out because they do not accurately describe this type of contact. A conformable contact would indicate that the layers were deposited continuously without interruption, a nonconformity would involve older igneous or metamorphic rocks being overlain by sedimentary rocks, and an angular unconformity would involve tilted or folded rocks being overlain by flat-lying rocks.
