Approached here via its eastern Atlantic facade at the level of the Caravelle peninsula, Martinique emerges in the center of the island arc of the Lesser Antilles. The area constitutes the eastern limit of the Caribbean plate by subduction of the Atlantic plate under the Caribbean plate since the Oligocene. The location of Martinique in the center of the island arc at the level of the convergence of the two northern arcs explains the continuity of the volcanic activity of the island since the Oligocene, without major hiatus nor superposition of products. From east to west and from south to north, there is therefore a complete succession of volcanic units, from the products of the ancient arc visible here on the Caravelle peninsula to the recent products of Mount Pelée. The geological interest of Martinique lies in the fact that the ancient products that outcrop there are accessible because they are not covered by more recent limestone or volcanic deposits.
