The Mulberry Rock recess exposes four different lithotectonic metamorphic units; these lithotectonic units were metamorphosed before the thrusting that occurred due to the Alleghanian orogeny. The lithotectonic units were divided into 1....
The geologic history of the southern Appalachians, specifically the rock suites comprising the Wedowee-Emuckfaw units in the Eastern Blue Ridge, have been the subject of debate for decades. A growing body of evidence implies the Taconic...
The southern Appalachian Inner Piedmont in east central Alabama and west Georgia consists of two tectonically separated Ordovician lithotectonic units: the structurally upper Dadeville Complex and the underlying Opelika Group. The...
Chondrules are silicate spherules in chondritic meteorites thought to have formed as free-floating melt droplets created by a transient heat source in the early solar system. Due to their ubiquity in asteroids, determining the origin of...
Refining the Cycling Framework of Vanadium Isotopes in Marine Environments and the Future Application to Better Reconstruct the Ancient Marine Redox Variations
Marine redox conditions are closely coupled with atmospheric oxygenation and essentially regulate the marine nutrient cycling (e.g., C, N, P, Fe, and S) in surficial processes, and marine life evolutions. Vast efforts have been invested, ...
The Allatoona fault is an internal, out-of-sequence thrust fault in the southernmost Appalachian hinterland, extending >280 km. Along the fault's nearly linear trace it cuts obliquely through Blue Ridge tectonostratigraphy, metamorphic...
