The volcanotectonic evolution of Flores Island, Azores (Portugal)
Azevedo, J. M. M.; Ferreira, M. R. PortugalFrom the study and interpretation of the volcanic products and structures of Flores Island, we infer that its volcanic history was dominated by two major periods: (1) proto-insular volcanism, which includes all the submarine and emergent activities; and (2) insular volcanism, consisting exclusively of subaerial eruptions. The first period includes two phases: (1) the oldest (2.2 to 1.5 Ma) of shallow submarine ...
Volcanic gaps and subaerial records ofpalaeo-sea-levels on Flores Island (Azore...
Azevedo, J. M. M.; Ferreira, M. R. PortugalThe morphological evolution of Flores Island, as commonly observed for volcanicislands, suggests (1) the balance between constructive processes (effusive and moderatelyexplosive volcanic activities and tectonic uplifting movements) and destructive processes (marine abrasion, stream erosion, crater-forming volcanic explosions, caldera collapses andtectonic subsidence) and (2) the recurrent fluctuations of the se...
