When did the volcanic islands of the lesser antilles form?

The volcanic islands of the Lesser Antilles formed primarily through volcanic activity that began in the late Cretaceous period, around 70 million years ago, and continued into the Cenozoic era. The formation is a result of the subduction of the Atlantic Oceanic plate beneath the Caribbean plate, leading to the creation of these volcanic arcs. The islands have been shaped by ongoing tectonic activity and eruptions, with some still active today.
