Over most of its length, the northern coast of Cuba is the dividing line between stable conditions (at least since the Middle [[Jurassic]]) to the north and west and very complex ones to the south. Although it is geologically deformed ([[:file:St58OverviewFG4.JPG|Figure 2]]), the part of the northern coast of Cuba extending from eastern [[Natanzas]] to western Oriente belongs to the Florida-Bahamas carbonate bank province. To the south, in part under an upper Eocene or younger cover, is a relatively narrow belt, 45-160 km (28-99 mi) wide, of intensely folded and faulted Middle Jurassic to middle Eocene rocks consisting, from north to south, of:
