The others are of oceanic origin, formed of the calcareous remains of marine life. By a strange freak of nature Guadeloupe unites the two formations, the eastern half of the island (Grande Terre) being of marine origin, while the western half, joined to the other by a narrow isthmus, is volcanic, like Martinique. With the exception of Barbados, the volcanic islands have been the more prosperous and important.
