... variations can be investigated at the continental scale by analysis of Paleogene strata in Laramide basins and the Gulf of Mexico. New U-Pb geochronologic data from detrital zircons in Paleogene fluvial strata of the Tornillo Basin in west Texas indicate relatively continuous deposition from 63 to 47 Ma...

... the North American Western Interior Seaway. As such, the Cretaceous-Tertiary (K-T) transition within the Tornillo Basin may provide an example of megascale stratigraphic cyclicity that is controlled by eustatic sea level within a fully fluvial succession. Thickening and thinning successions of FACs record...

... of megabreccia units, coupled with paleoflow analysis, argue that major Laramide topographic relief in western Texas persisted into the Middle Eocene and that detritus was shed toward the Tornillo basin to the east. These data, when viewed within the context of regional tectonic patterns, suggest that Laramide...
