Peralkaline Felsic Magmatism of the Atlantic Islands
The oceanic-island magmatic systems of the Atlantic Ocean exhibit significant diversity in their respective sizes, ages, and the compositional ranges of the magmas they have produced. Nevertheless,Expand
Thick-skinned tectonics in a Late Cretaceous-Neogene intracontinental belt (High Atlas Mountains, Morocco): The flat-ramp fault control on basement shortening and cover folding
Abstract Most of the structural studies of the intracontinental High Atlas belt of Morocco have dealt with the central part of the belt, whose basement does not crop out. Here we study the AlpineExpand
Grandes terremotos en Azores
The history of the Azores archipelago, from its discovery and settlement in the first half of the 15th century through the present, is marked by the social and economic impacts produced byExpand
Recent uplift of the Atlantic Atlas (offshore West Morocco): Tectonic arch and submarine terraces
Abstract Re-examination of marine geophysical data from the continental margin of West Morocco reveals a broad zone characterized by deformation, active faults and updoming offshore the High AtlasExpand
The 2014–15 eruption and the short-term geochemical evolution of the Fogo volcano (Cape Verde): Evidence for small-scale mantle heterogeneity
Abstract Recurrent eruptions at very active ocean island volcanoes provide the ideal means to gain insight on the scale of spatial variations at the mantle source and on temporal changes of magmaExpand

Broad plumes rooted at the base of the Earth's mantle beneath major hotspots
The use of a whole-mantle seismic imaging technique is described that reveals the presence of broad, quasi-vertical conduits beneath many prominent hotspots, and it is shown that the imaged conduits are robustly broader than classical thermal plume tails, suggesting that they are long-lived, and may have a thermochemical origin.

Chapter 12 Eruptive frequency and volcanic hazards zonation in São Miguel Island, Azores
Abstract São Miguel Island comprises five active volcanic systems, including three central volcanoes with calderas and two basaltic fissure systems. Volcanic eruptions in São Miguel are of basalticExpand
Nannofossils in 2011 El Hierro eruptive products reinstate plume model for Canary Islands
New age data obtained from calcareous nannofossils in sedimentary xenoliths erupted during the 2011 El Hierro events are reported, which date the sub-island sedimentary rocks to between late Cretaceous and Pliocene in age, reinstate the mantle-plume hypothesis as the most plausible explanation for Canary volcanism.
