Taken collectively, the petrographic evidence for basement-contact relations overwhelmingly supports a tectonic contact in most locations, and an angular unconformity
in one locality, Timber Brook.
Abstract: The Warrensburg Sandstone, a Pennsylvanian alluvial valley-fill in Johnson County, Missouri, lies with angular unconformity
on Desmoinesian Pennsylvanian marine strata comprised mainly of shales and thin limestones.
The growing portfolio of prospects includes large anticlinal structures, angular unconformity
pinch-outs, and turbidite fans within the Upper Cretaceous section.
