Pliocene-Pleistocene depositional sequences of the northern Gulf of Mexico, offshore Texas and Louisiana
This work tests the consistency of sequence stratigraphic methods by comparing the model documented in this study with previous models for growth faulted, siliciclastic environments. Interpretations derive from sequence ...
Volatile cycling and the thermal evolution of planetary mantle
The thermal histories of terrestrial planets are investigated using two parameterized mantle convection models for either Earth like planets and planets with no active plate tectonics. Using parameterized models of mantle ...
Kinematic analysis of the deformational structures on eastern Isla de Margarita, Venezuela
Because of its strategic location at the intersection of three regional trends, a kinematic study of the deformation on Isla de Margarita was undertaken to provide additional constraints for Caribbean plate tectonic models. ...
Petrogenesis of plutons and hypabyssal rocks of the Bering Strait region, Chukotka, Russia
Subduction of an oceanic plate beneath the Bering Strait region resulted in the formation of an extensive magmatic belt along the margin of the region during the Cretaceous. Plutons and gneiss domes of this age are broadly ...
SEDIMENTOLOGY AND DIAGENESIS OF THE UPPER CRETACEOUS AUSTIN CHALK FORMATION, SOUTH TEXAS AND NORTHERN MEXICO
The Austin Chalk Formation in south Texas and northern Mexico represents an "impure" onshore depositional chalk deposited within an environmental framework characterized by distinct paleobathymetric variations. Relatively ...
