Sedimentology and Stratigraphy

Sedimentological and physical stratigraphic approaches are being applied to problems of tectonics, paleoceanography, and depositional systems. 

Brad Sageman’s research, whether focused on collection of geochemical samples, paleobotanical specimens, or bentonites for geochronologic analysis, is fundamentally based on high-resolution stratigraphic analysis of core and outcrop successions. His particular expertise includes the biostratigraphy, cyclostratigraphy, event stratigraphy, and sequence stratigraphy of Cretaceous strata in the Western Interior U.S. (but he has also worked on Cretaceous successions in Canada, Mexico, Colombia, and Tibet) and includes DSDP and ODP sites in his sample inventory as well.  He is interested in the sea level history of the Cretaceous, as recorded in deposits of the Western Interior basin, and has contributed to the debate concerning Cretaceous glacioeustasy.
