The Azores Plateau in the North Atlantic is a classic example of near-ridge oceanic plateau (600 km) associated with the upwelling of the Azores mantle plume. The radiogenic isotope signatures of Azores lavas show systematic inter-island variations,

Intraplate magmatic provinces found away from plate boundaries provide direct sampling of the composition and heterogeneity of the Earth's mantle. The chemical heterogeneities that have been observed in the mantle are usually attributed to recycling

Spatial isotope variations in oceanic island basalts hold clues to the geochemical structure of mantle plumes. This signal is however susceptible to contributions from non-plume sources and modifications by physical processing in the upper mantle, i.

We present 176Hf/177Hf isotope ratios on 41 previously well-characterized subaerial and submarine samples from the Azores islands of Sao Miguel, Terceira, Graciosa, Faial, Pico and the Joao de Castro seamount (on the Terceira Rift). In eNd–eHf isot

The Chachimbiro volcanic complex (CVC) is a composite volcano located in the frontal part of the Ecuadorian Quaternary Arc. Four periods of activity can be differentiated in Chachimbiro ∼400 ka-long volcanic history, named CH1 (405.7 ± 20.0–298.

The Yanaurcu volcanic center in the Ecuadorian frontal arc is characterized by several epochs of activity from the Early Pliocene to approx. 61 ka, with important changes in geochemistry and isotope ratio values throughout its history. Most of its un
