Voring Plateau volcanic margin: extension, melting, and uplift

Abstract

Seismic sections and ODP drilling information at the Voring Plateau volcanic passive margin have provided the framework for modelling the generation of basaltic magma and uplift associated with the early Tertiary rifting event. A simple uniform lithosphere stretching model of subsidence, incorporating partial melting in the upper mantle, accounts for both the volume of liquid basalt produced and the amount of uplift, when a minor temperature excess of approximately 50°C is assumed at the base of the lithosphere. -Authors
