Mesozoic alkaline volcanism and mantle evolution of the southwestern São Francisco craton, Brazil
… of crust, derived in the Proterozoic from mantle reservoirs similar to the sources for modern oceanic basalts, were accreted onto the pre-existing Archean nucleus during the Brasiliano orogenic event.

Understanding late Cenozoic western United States mantle dynamics and surface tectonics using forward-adjoint data assimilation models
Understanding mantle evolution is essential for investigating many processes of the Earth’s surface and interior. A straightforward way to study mantle evolution is through mantle convection simulation. However, a self-consistent and fully dynamic representation of past mantle convection for the …

Geochemistry of Variscan lamprophyre magmatism in the Saxo-Thuringian Zone
Lamprophyres are mantle-derived magmatic rocks, commonly occurring as dikes. They are readily identified from their field setting, petrography, chemical and mineralogical composition. These rocks not only provide important information on melting processes in the mantle, but also on geodynamic …

Neotectonic evolution of Grand Canyon : interaction between volcanism, river incision, epeirogenic uplift, and faulting
… uplift, and faulting on the landscape evolution of the Grand Canyon region. In the first chapter the migration of increasingly asthenospheric basaltic volcanism is used to constrain lithospheric modification of the Colorado Plateau margins. Buoyancy modification of the upper mantle, …
