Chemical composition and 87Sr/86Sr signatures at two active central volcanoes i...
Ferreira, L.; Cruz, J.Virgílio; Viveiros, F.; Durães, N.; Coutinho, R.; Andrade, C.; Santos, J. F.Rainwater samples were collected during final of February and early March of 2022, at Furnas and Fogo volcanoes, São Miguel (Azores), both of which display secondary manifestations of volcanism. The major-ion composition reveals that marine aerosols contribute significantly to the chemistry of these rainwaters, showed by the proximity of some samples to the Na/Cl ratio of the seawater. The 87Sr/86Sr ratios (0.7...
Hydrochemical and isotopic composition (87Sr/86Sr) of rainwater from São Miguel...
Ferreira, L.; Cruz, J. Virgílio; Viveiros, F.; Durães, N.; Coutinho, R.; Andrade, C.; Santos, J. F.Rain chemistry has been the subject of extensive research over the last few decades in order to determine the geochemical mechanisms that control the water composition (e.g., Négrel et al., 2007). In the present work rain samples were collected at Furnas and Fogo volcanoes, located in São Miguel (Fig.1a), in order to characterize the chemical fingerprint of the rainwaters and to investigate a possible interacti...
