The West Indies are the summits of a submerged mountain chain, thecontinuation of which must be sought in the mountains of central Honduras. InHaiti, the chain divides, one branch passing through Jamaica and the otherthrough Cuba, the Cayman Islands, and the Misteriosa bank.
Suess divides the West Indies into three zones: The first zone is entirelyof volcanic origin and includes many recent volcanic cones. It includes thearcuate string of islands, which extends from Saba and St. Kitts to theGrenadines and Grenada. The western half of Guadeloupe belongs to this group.The second zone consists of a geanticline, of which the sedimentary rocks rangefrom the Jurassic to the Quaternary, but consist chiefly of Lower Tertiarysediments. In the west it is broad, including the whole of the GreaterAntilles; but in the east it is restricted to a narrow belt, which includes theVirgin Islands (except Anegada), Anguilla, St. Bartholomew, Antigua, theeastern part of Guadeloupe and part of Barbados. The islands that compose thethird zone are flat and low. Like the second, this zone is broad in the westand narrow in the east; it includes the Bahamas, Anegada, Sombrero, Barbuda,and part of Barbados. Geologically, Florida and the plain of Yucatan may beregarded as belonging to it.
Trinidad and Tobago, though geographically adjacent to the Lesser Antilles,arc geologically a detached part of the South American continent. Thecrystalline complexes of northern Trinidad and of Barbados are a continuation,en echelon, of the crystalline axis of the promontory of Paria. The foldedCretaceous and Tertiary of the central and southern parts of Trinidad representa continuation of the folded sediments of the Paria district of Venezuela.
