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. ...
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 ...
Time-lapse imaging of fault properties at seismogenic depth using repeating earthquakes, active sources and seismic ambient noise
The time-varying stress field of fault systems at seismogenic depths plays the mort important role in controlling the sequencing and nucleation of seismic events. Using seismic observations from repeating earthquakes, ...
Pre-Tertiary stratigraphy, magmatism, and structural history of the Central Jackson Mountains, Humboldt County, Nevada
The Jackson Mountains (JM) are part of the early Mesozoic continental arc in northwest Nevada, which was constructed upon previously accreted Paleozoic basement. The stratigraphy of the Paleozoic basement exposed in the ...
