Fenestellid and polyporid Bryozoa of the Lower Mississippian Warsaw Formation of the Mississippi River outcrop belt are represented by nine genera of Fenestellidae (three of which are new--Banastella, Cubifenestella, and ...

The Ste. Genevieve Fault System (SGFS) is a 118-mile-long (190 km-long) belt of WNW-trending faults that extends from southwestern-most Illinois, across the Mississippi River, and into southeastern Missouri, in the central ...

Redox reactions greatly influence metal and metalloid mobility, as different oxidation states can exhibit diverse geochemical behavior controlling solubility and adsorption affinity. Elucidating these processes is important ...

The differential motion, lateral velocity gradient, and topography of the Earth’s inner core make the temporal change of the core phases’ arrival times observable in waveform doublets, a pair of events happened at the same ...

Vanadium (V) is a redox-active transition metal used widely to understand terrestrial magmatic processes. Measurements of the V isotopic composition of peridotites, the dominant rock of upper mantle, and primitive meteorites ...

Recent advances in high-resolution multibeam bathymetric imaging have revealed step-like structures interpreted as cyclic steps, or sediment waves, along the bottom of deep-sea canyons and channel levees. These bed features ...

The tidally-influenced fluvial zone (TIFZ), or ‘fluvial-tidal’ transition, is an environment characterized by unidirectional fluvial, bidirectional tidal, and oceanic oscillatory currents. TIFZ environments (i.e., deltas ...
