Developments in Alipine Geodynamics

Large scale simulation and observations in geodynamics

We contrast the concepts of computational simulation as practiced in computer assisted design with that of numerical modeling of geology and other observational sciences in which controlled experiments are not available. We highlight the role of the modeller in subjectively weighting observations, modelling and experience to find a preferred geological model.

High - Performance Modelling in Geodynamics

Modelling of geodynamic processes like mantle or core convection has strongly improved over the last two decades thanks to the steady development of numerical codes that tend to incorporate a more and more realistic physics. High-performance parallel computations allow the simulation of complex problems, such as the self-consistent generation of tectonic plates or the formation of planetary mag...

Alkaline Rocks and Geodynamics

105 Abstract: Origin of A-type alkali feldspar granites is currently the subject of a world-wide debate. Contrasting hypotheses have been proposed, which range from an entirely crustal origin to an almost complete mantle derivation. A-type alkali feldspar granites belong to either unimodal granite (rhyolite)-dominated association, or bimodal gabbro (basalt)-granite (rhyolite) suite. It is argue...
