Erosional history of the New River, southern Appalachians, Virginia
Much of the bedrock surface of the Southern Appalachian Valley and Ridge Province is covered by a veneer of surficial deposits classified as alluvium, colluvium, and residuum. In this investigation the surficial geology of a 60-km<sup>2</sup> area of the New River drainage system was mapped at a …

Volatiles as a link between planetary interiors and the environment
… terrestrial volatile cycling, I also explore the erosional history of Titan as recorded in valley networks carved by rivers of liquid hydrocarbons.

Beekmantown Formation-Middle Ordovician limestone unconformity on the northwest limb of the Green Ridge anticline near Fincastle, Virginia
The depositional and erosional history can be summarized as follows: 1) Subtidal carbonate shelf sedimentation through Early Ordovician (and including early Middle Ordovician White Rock?) time represented by the Beekmantown Formation. 2) Emergence of a Beekmantown terrain due to eustatic lowering …

Ravine alluvial fans as records of landscape change in the Le Sueur River Basin, southern Minnesota
… rates over time from both impacts, with the erosional history preserved in alluvial fans at the mouths of ravines where they terminate on fluvial terraces. Establishing a post-settlement chronology is difficult in the highly erosive knickzone of the Le Sueur. We take advantage of six fan …

Modelling the Holocene evolution of coastal gullies on the Isle of Wight
… of the various driving factors, the Holocene erosional history of the Isle of Wight gullies was then simulated using a LEM. In a preliminary set of simulations a 'traditional' (i.e. with no consideration of parameter uncertainty) retrodictive modelling approach was applied, in which driving …

Geology of the Phil Pico Mountain Quadrangle, Daggett County, Utah, and Sweetwater County, Wyoming
… well have provided additional constraints on the erosional and uplift history of this section of the north flank of the Uinta Mountains. Phil Pico Mountain is largely composed of the conglomeratic facies of the early Eocene Wasatch and middle to late Eocene Bridger Formations. These formations are …
