The Virgin Islands (Spanish: Islas Vírgenes) are an archipelago between the North Atlantic Ocean and northeastern Caribbean Sea, geographically forming part of the Leeward Islands of the Lesser Antilles in the Caribbean islands or West Indies. . Geologically separated from the Lesser Antilles by the Anegada Passage and from the Greater Antilles by the Mona passage, all the islands except for Saint Croix lie on the same carbonate platform and insular shelf, known as the Puerto Rico Bank, and same tectonic plate, known as the Puerto Rico–Virgin Islands microplate. .
