Multi-stage evolution of a sub-aerial volcanic ridge over the last 1.3 Myr: S. Jorge Island, Azores Triple Junction
TL;DR: In this paper, K/Ar dating and geochemical analyses have been carried out on the WNW-ESE elongated oceanic island of S. Jorge to reconstruct the volcanic evolution of a linear ridge developed close to the Azores triple junction.
Reconstructing the architectural evolution of volcanic islands from combined K/Ar, morphologic, tectonic, and magnetic data: the Faial Island example (Azores)
A. Hildenbrand,Fernando O. Marques,A.C.G. Costa,A.L.R. Sibrant,Pedro Silva,B. Henry,Jorge Miguel Miranda,Pedro Madureira +7 more
TL;DR: In this paper, a multi-disciplinary study of the successive stages of development of Faial (Azores) during the last 1 Myr is presented, using high-resolution digital elevation model (DEM), and new K/Ar, tectonic, and magnetic data, in response to complex interactions between volcanic construction and mass wasting, including the development of a graben.

Mantle source heterogeneity, magma generation and magmatic evolution at Terceira Island (Azores archipelago):: Constraints from elemental and isotopic (Sr, Nd, Hf, and Pb) data
TL;DR: In this article, the present-day mantle heterogeneity in the Azores region through the study of two active volcanic systems from Terceira Island is addressed, and it is shown that mantle heterogeneities are detectable even when “coeval” volcanic systems (Santa Barbara and Fissural) erupted less than 10 km away.
Journal ArticleDOI
The insular shelves of the Faial-Pico Ridge (Azores archipelago): A morphological record of its evolution
Rui Quartau,Rui Quartau,José Firmino Aguilar Madeira,Neil C. Mitchell,Fernando Tempera,Pedro Silva,Pedro Silva,Filipe Brandão +7 more
TL;DR: In this paper, multibeam bathymetry, high-resolution seismic reflection profiles, and sediment samples are used to characterize the morphology of the insular shelves adjacent to Pico Island.
