Various rock types and bedding contribute to Waulsortian-like buildups in the Fort Payne Formation. Krause and Meyer (2004) identified five facies in Kentucky buildups, and Knox and Stapor (2003) described four facies in Tennessee buildups. Figure 1 is a diagram of typical Fort Payne buildups in Kentuck, demonstrating considerable variation in facies distribution in different buildups.
Figure 1. Fort Payne buildups (mud mounds) are extremely variable,
but several facies are typical. Not all facies occur in all buildups.
