The Wallbridge discontinuity expands eastward, so that Silurian and Lower Devonian strata probably do not occur beneath the metamorphic overthrust. The pre...

In the southeasternmost exposures, faults juxtapose late Pleistocene (ca. 125 ka), near-shore, marine sediments with the older Colorado River delta sediments that are the focus of this field trip. The Cerro Prieto fault forms the principal active...

.... The chert sequence grades northeastward through a shelf–slope–basin-plain transition into a thick black-shale basinal facies. These units were deposited during the classic Acadian orogeny in New England and the Catskill delta's progradation across the central Appalachian foreland—the major clastic response...

Although Johnson’s cycles were based on successions of transgressive and regressive lithologies, the association between cyclic dark shales and orogeny via lithospheric flexure was not made until 1985 in two articles on the Catskill delta complex ( Ettensohn, 1985a , b ).
