Abstract
The variable elevation of raised Quaternary marine terraces in the Greater Antilles is interpreted to be due principally to variable tectonic uplift. Such terraces are highest and most numerous in northwestern Haiti and southeastern Cuba. Elsewhere, they tilt noticeably away from this focus and are at lower elevations and less numerous. The dome-like uplift is in a region characterized by graben faulting and late Cenozoic alkaline volcanism, an association which invites comparison with the Rhine and East African Rift Systems.
Quaternary tilting is also inferred from the depth variations over shallow submarine banks. A profile across a number of these banks to the east of Jamaica indicates a local synclinal axis.
