CONCLUSIONS

Interaction of Atlantic bathymetric features with the leading plate margin has induced a series of effects of the evolution of the Lesser Antilles Island Arc.
The presence or absence of aseismic ridges on the subducting Atlantic plate is the most constraining factor in all aspects of arc volcanism.
Subduction of large buoyant ridges leads to regional collision events while subduction of non-buoyant ridges creates local interactions with the overriding plate.
Volcanism along the arc varies in periodicity and composition.
