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 ...
Discrete simulations of density-driven volcanic deformation: Applications to Martian caldera complexes
We have carried out 2-D numerical simulations using the discrete element method (DEM) to investigate density-driven deformation in Martian volcanic edifices and how it affects the development of caldera complexes. These ...
The Texas mud blanket: Understanding fine-grained sediment flux in the NW Gulf of Mexico during the previous transgression
The evolution and source of the Texas Mud Blanket (300 km3) was determined from 26 new radiocarbon dates and from ∼3000 km of 2D seismic data. Sediment flux (km3/ka) was calculated from this combined dataset. XRD reveals ...
Low viscosity channels and the stability of long wavelength convection
Mantle convection simulations with a low viscosity channel, akin to the Earth's asthenosphere, are characterized by long wavelength flow structure. Boundary layer theory predicts that as the viscosity of the channel ...
