Upper Cambrian Sawatch and Peerless formations exposed in the vicinity of Manitou Springs, Colorado, U.S.A., are part of the Cambrian inner detrital belt of North America. Transgressive systems tract (TST) deposits composed of quartz-rich shoreline and nearshore sandstone (Sawatch Formation) are overlain by coarse-grained, glauconite-rich.

This paper presents a stratigraphic and paleontologic study of the Upper Cambrian exposed in three linear belts in the central Appalachians: (1) in the Nittany Arch region of southern Pennsylvania (Warrior and Gatesburg formations), (2) in the Shenandoah-Cumberland Valley of Virginia, West Virginia, Mary-land, and Pennsylvania (Elbrook and Conococheague formations), and (3) the Frederick.

The general purpose of the stratigraphic studies has been (1) to determine the paleogeography of Upper Cambrian stratigraphy of central Colorado.

Daily () established an informal series of twelve Lower Cambrian trilobite-based faunal assemblages that for many years were the basis of Lower Cambrian correlations between Australia and other continents.

However, Daily provided no formal taxonomic treatment or stratigraphic ranges of the taxa. Jell (in Bengtson et al., ) erected four trilobite zones: Abadiella huoi (base). Cambrian–Ordovician of the western U.S.

Parker, J. Roberts. Abstract. Devonian and Mississippian rocks cover most of the central part of the Colorado Plateau and range in thickness from a few feet in the eastern part to a combined total thickness of approximately feet along the western.

To document the depositional architecture and sequence stratigraphy of the Upper Jurassic Hanifa Formation in central Saudi Arabia, three composite sections were examined, measured and thin section analysed at Al-Abakkayn, Sadous and Maashabah mountains.

Fourteen microfacies types were identified, from wackestones to boundstones and which permits the recognition of five lithofacies. The Early Cambrian represents roughly the Terreneuvian and series 2, the Middle Cambrian approximately the Miaolingian, and the Late Cambrian roughly the Furongian.

This practice is preferred here because the trace fossils do not deliver a stratigraphic age detailed enough for correlation with the modern (well defined) stratigraphic stages.
