Depositional Model of a Late Cretaceous Dinosaur Fossil Concentration, Lance Formation
… bonebed. To accomplish this task we utilized 1D facies analysis of surrounding units and 3D analysis of the bonebed. The nature of the outcrop limited facies analysis to 1D. Four measured stratigraphic sections, each containing the bonebed unit, were taken and used in facies analysis. In …

Marine offshore to alluvial plain transitions within the "Chemung"-Hampshire interval (Upper Devonian) of the southern central Appalachians
… erosion of the Acadian Mountains to the east. Facies of the "Chemung" indicate deposition within three major, laterally adjacent environments. The predominating facies assemblage constitutes upward-coarsening sequences interpreted as offshore to upper shoreface progradational successions. The …

The Lower Pennsylvanian New River Formation: a Nonmarine Record of Glacioeustasy in a Foreland Basin
… consist predominantly of nonmarine, coal-bearing facies that developed within a fluvio-estuarine, trunk-tributary drainage system in a foreland-basin setting. Sheet-like, sandstone-mudstone bodies (up to 100 km wide and 70 m thick) developed in an axial trunk drainage system, whereas channel-like, …

Sedimentology and Stratigraphy of the Coalmont Formation, Northwestern, North Park, Colorado, U.S.A.
… a variety of fluvial and lacustrine sedimentary facies that have not been documented in depth. Using geologic mapping, measured stratigraphic sections, outcrop scale sedimentology, paleocurrent analysis, sedimentary petrography and fluvial-lacustrine architectural element analysis, this study …

CENOZOIC EXTENSION OF THE LAKE TANGANYIKA RIFT, EAST AFRICA: STRUCTURES, TECTONOSTRATIGRAPHY AND PALEOENVIRONMENTAL RECONSTRUCTION
… during its high stands. Spectacular oversized deltaic prograding clinoforms, which may be linked to the outflow of Lake Rukwa, are observed in seismic reflection data within the Lake Tanganyika Rift on the Karema platform. In the absence of borehole data in this area, a numerical modelling …
