Analysis indicates latest movement varied at each site and was down the present dip of the "décollement." The directions inferred range from westward through southward to eastward. When combined with evidence of Tertiary age for latest movement on the "décollement," the data support a denudation fault model rather than regional Mesozoic décollement models. This suggests that the tectonic pattern may have more to do with post-Eocene evolution of the Great Basin ignimbrite-block fault province than with the Mesozoic Sevier orogenic belt.
