The geology of the island of Dominica, at the center of the Lesser Antilles island arc, has been subdivided into four stratigraphic divisions: Division 1 (upper Miocene) is dominated by mafi c volcanism; Division 2 (upper Pliocene‐lower Pleistocene) is characterized by the development of two large stratovolcanoes over a 2 million year period; Division 3 (lower to upper Pleistocene) represents a period of island-wide quiescence except at the north and south of the island where two new centers developed on the fl anks of the older stratovolcanoes; and Division 4 (upper Pleistocene‐ Holocene) characterized by the formation of numerous Pelean centers throughout the island. Three of these centers also produced large-volume pumiceous deposits that resulted in the formation of two calderas (Morne Trois Pitons and Wotten Waven).
