ANALISI QUANTITATIVA DELL'EVOLUZIONE DI UN RIFT: IL MARGINE SARDO DEL MAR TIRRENO

Abstract

We present the results of quantitative forward model­ing of the Sardinian rifted margin of the Tyrrhenian Sea. Firstly, we investigate the thermo-mechanical structure that affects the thinning of the lithosphere across the margin. The role of lithospheric necking during basin formation, con­strained by basement topography, Moho depth and gravity anomalies, is modeled for different compensation models. Independent constraints are obtained from the analysis of the predicted thermal structure. [...]
