Tectonic and sedimentary evolution of the Bransfield Basin, Antarctica
Application of sequence stratigraphy to seismic reflection profiles from the Bransfield Basin indicates that this modern back-arc basin formed in response to cessation of subduction at the South Shetland trench at 4 Ma. ...
Seismic facies analysis and depositional history of an incised valley system, Galveston Bay area, Texas
The history of the incised river valley underlying Galveston Bay was determined by examining the distribution of depositional units and the relationships between them. Initial incision of the valley occurred after the ...
Tectonostratigraphic evolution of Neuquen Basin, Argentina
The area is located in west central Argentina, east of the Andes. It was a Mesozoic backarc basin which evolved into a foredeep basin during the upper Cretaceous, when a fold and thrust belt was formed to the west. The ...
Clay mineral facies development in recent surface sediments of the northeastern Gulf of Mexico
Three major rivers supply the bulk of the clay mineral matter to the northeastern Gulf of Mexico. The type of clay supplied is a function of the clay minerals in the soils of the source basins and appears to be largely ...
A comparison of some Eocene and modern sediments by coarse fraction analysis
Examination of an ancient sedimentary basin can provide only an incomplete geologic picture, because it reveals merely the anatomy of a dead body. Physiology must be learned on a living organism, and likewise the geologist ...
