4. Volcanism at the tip of a propagating rift : the Heimaey volcanic centre, south Iceland
Abstract : Primary magmas are generated by 4-6% partial melting near the garnet-spinel stability fields beneath Heimaey (i.e. 80-65 km depth). The magmas fractionate 31% olivine and clinopyroxene en-route to ponding at the base of the crust (and forming a parental Vestmannaeyjar magma). READ MORE

5. Interaction of Segments along Rifts that Separate Continents and Ridges that Spread Ocean Floors
Abstract : The face of the Earth is constantly renewed by continental rifts that open and allow ridges to spread oceanic floor. Both types of these linear extensional structures are morphologically and structurally segmented. This thesis aims to provide insights into the interaction of such segments as they propagate and mature. READ MORE
