Integration of natural data within a numerical model of ablative subduction: A possible interpretation for the Alpine dynamics of the Austroalpine crust

Autor: Roda, Manuel, Spalla, Maria Iole, Marotta, Anna Maria

Publikováno v: Journal of Metamorphic Geology, 2012

A numerical modelling approach is used to validate the physical and ge- ological reliability of the ablative subduction mechanism during Alpine con- vergence in order to interpret the tectonic and metamorphic evolution of an inner portion of the Alpi

Report

The effects of the overriding plate thermal state on the slab dip in an ocean-continent subduction system

Autor: Roda, Manuel, Marotta, Anna Maria, Spalla, Maria Iole

Publikováno v: Comptes Rendus Geoscience, Volume 343, pp. 323-330, 2011

To evaluate the effects of variations in the thermal state of the overriding plate on the slab dip in an ocean-continent subduction system, a 2-D finite element thermo-mechanical model was implemented. The lithosphere base was located at the depth of

Report

Numerical simulations of an ocean/continent convergent system: influence of subduction geometry and mantle wedge hydration on crustal recycling

Autor: Roda, Manuel, Marotta, Anna Maria, Spalla, Maria Iole

Publikováno v: Geochem. Geophys. Geosyst., Volume 11, Number 5, ISSN: 1525-2027, 2010

The effects of the hydration mechanism on continental crust recycling are analyzed through a 2D finite element thermo-mechanical model. Oceanic slab dehydration and consequent mantle wedge hydration are implemented using a dynamic method. Hydration i
