Wave processes and geologic responses on the floor of the Yellow Sea Wave processes and geologic responses on the floor of the Yellow Sea

The floor of the Yellow Sea is a geologically mundane surface: it is nearly horizontal, lacks relief, and, with few exceptions, is devoid of conspicuous geomorphologic features. However, it is the principal repository for the prodigious sediment load of the Huanghe (Yellow River); and, due to its inherent shallowness (average depth is 40 m), it is frequently stressed by waves generated...

Modelling of turbidity currents on Navy Submarine Fan, California Continental Borderland Modelling of turbidity currents on Navy Submarine Fan, California Continental Borderland

Several Holocene turbidites can be correlated across much of Navy Fan through more than 100 sediment core localities. The uppermost muddy turbidite unit is mapped throughout the northern half of the fan; its volume, grain-size distribution and the maximum height of deposition on the basin slopes are known. These parameters can be related to the precise channel morphology and...

Upper Triassic Barranca Group; Nonmarine and shallow-marine rift-basin deposits of northwestern Mexico Upper Triassic Barranca Group; Nonmarine and shallow-marine rift-basin deposits of northwestern Mexico

The 3,000-m-thick Upper Triassic Barranca Group in the Sierra de San Javier in east-central Sonora, Mexico, is composed, in ascending order, of the Arrayanes, Santa Clara, and Coyotes Formations. The Arrayanes and Santa Clara Formations are composed of fluvial and marine-delta deposits of quartzose and arkosic sandstone, conglomerate, shale, and siltstone; the Santa Clara Formation...

Molluscan paleoecology and sedimentation patterns of the Cenomanian-Turonian extinction interval in the southern Colorado Plateau region Molluscan paleoecology and sedimentation patterns of the Cenomanian-Turonian extinction interval in the southern Colorado Plateau region

Lithology, carbonate and organic carbon geochemistry, and molluscan macrofauna were investigated in fine-grained clay-dominated strata spanning the Cenomanian-Turonian Stage boundary in the southern Colorado Plateau region. Analyses of these data show basinal and onshore to offshore changes in sedimentologic and molluscan assemblage trends through the upper Cenomanian Sciponoceras...

Assessing the solubilities and reaction kinetics of aluminous minerals in soils Assessing the solubilities and reaction kinetics of aluminous minerals in soils

The use of chemical thermodynamics and reaction kinetics is necessary to quantitatively model the transformation of aluminous minerals and their dissolved constituents in soils and other geochemical systems. Soils are thermodynamically open systems subject to atmospheric and biological forces and do not attain overall thermodynamic equilibrium with respect to either mass or time. However...
