Geology of the Collectivity of Saint Martin
The geology of the Collectivity of Saint Martin consists of andesite tuff and tuff breccia from the middle and late Eocene, intruded by hypabyssal basalt, quartz diorite and younger andesite. Volcanic activity led to metamorphism of many rocks and the tilting and folding of the tuff series. Limestone and marl was later unconformably deposited atop the eroded volcanic rocks as volcanic activity shifted elsewhere.[1] Large boulder ridges and solitary boulders on high cliffs suggest tectonic-related tsunamis.[2]

†Physiographically, these continental islands are not part of the volcanic Windward Islands arc, although sometimes grouped with them culturally and politically.

#Bermuda is an isolated North Atlantic oceanic island, physiographically not part of the Lucayan Archipelago, Antilles, Caribbean Sea nor North American continental nor South American continental islands. It is grouped with the Northern American region, but occasionally also with the Caribbean region culturally.
