Volcanic Conduits of the Chã das Caldeiras Caldera (Fogo Island, Cape Verde) – REE and Fe Crystalchemistry
2017
Abstract Topsoils of pyroclastic materials collected on two volcanic conduits of the Cha das Caldeiras caldera of the oceanic Fogo Island (Cape Verde) were studied. Significant positive Eu anomalies were found in both pre-historic and historic cones, which together with the presence of jarosite, may be considered hydrothermal signatures that survived in this surficial semi-arid environment.
