Geology Of The Jacksonville 7.5 Minute Quadrangle And U–Pb And (U–Th)/He Reveal Sediment Routing And Uplift In The Southern Appalachian Valley And Ridge Province, Derek L. Spurgeon
MSU Graduate Theses
The southern Appalachian Mountains have experienced multiple deformation events having undergone two full Wilson cycles. The foreland Valley and Ridge province is composed of sedimentary Paleozoic rock that range in age from earliest Cambrian to Middle Pennsylvanian. This sedimentary basin was intensely folded and faulted during the collision of Gondwana during the Middle to Late Carboniferous Period. From previous geologic structural mapping that has taken place, some large-scale structures in the Valley and Ridge Province seem to be out of sequence. To better understand the relationships in these structures, geologic mapping in high detail at the 1:24,000 scale coupled with …

Landslides are common hazards that produce devastating effects worldwide. Within the United States, the Appalachian Mountains are identified as an area of moderate to high susceptibility and incidence for landslides (Mirus et al., 2020; Wieczorek and Morgan, 2008). Given the presence of active seismic zones (eastern Tennessee and Giles County seismic zones) and variable rainfall due to seasonal storms (hurricanes) throughout the Appalachians, ancient earthquake activity or intense rainfall may trigger mass wasting events. Regional bedrock joints may further control the susceptibility of landslides to develop in specific locations during trigger events by providing a pre-existing weakness in the substrate. …
