Structural Development, Yates Area, Texas

The marked Cretaceous surface structure overlying arched Permian limestones in the Yates area in eastern Pecos County, Texas, was developed by salt solution rather than folding. The solution was active in two stages. In the first, salt was removed from the crest of the dome and the hole left by this solution was filled with clastics. Cretaceous beds were laid down flat over this clastic plug. Post-Cretaceous solution developed a ring syncline around the plug and produced the present surface structure.
