Extensive chert gravels underlying the Smithland and higher erosion surfaces of the uppermost portion of the Mississippi embayment are considered remnants of three coalescing alluvial fans related to the ancestral Mississippi, Cumberland-Ohio, and Tennessee rivers. The shape and topographic form of the largest of these remnants, the Smithland surface of western Kentucky, best illustrates an alluvial-fan origin. The ancestral Tennessee and Mississippi alluvial fans have contrasts in direction of… Expand

Petrology of Pliocene Mississippi River Alluvium: Provenance Implications
Pliocene Mississippi River terrace gravels, the Upland Complex, crop out east and west of the present Mississippi River in the northern Mississippi Embayment. As the only sedimentary unit in theExpand
Paleocurrents and Paleogeography
The objective of this paper is to review the criteria used for direction of sediment transport and to outline the ways in which such knowledge can be used to make paleogeographic reconstructions. TheExpand
Geology of the Late Neogene Pipe Creek Sinkhole ( Grant County , Indiana )

Possible Relict Meanders of the Pliocene Mississippi River and Their Implications
Although the late Quaternary history of the Mississippi River, the largest North American river, has been intensely studied, its Pliocene history is largely unknown. We assert that large relictExpand

The morphological, sedimentary and hydraulic properties of two coarse clastic (pebble) beaches along the heritage coast of Glamorgan, Wales
This thesis attempts to clarify those morphological, sedimentary and hydraulic properties which typify coarse clastic beaches. A tracer study on a low energy beach at Gileston identified shape andExpand
Quaternary Uplift in the Lower Mississippi River Valley
Discontinuous high-level terrace remnants of the ∼3.1 Ma ancestral Mississippi River floodplain, locally called the Upland Complex (UC), are mapped from Louisiana into Illinois. We interpret the UCExpand
