The geology of Cuba differs significantly from that of other Caribbean islands because of ancient 900 million year old Precambrian Proterozoic metamorphic rocks in the Santa Clara province and extensive Jurassic and Cretaceous outcrops. Western and central Cuba are an orogenic belt—mountains formed by crumpling and uplift—created by the collision of an island arc in the Cretaceous with the Florida-Bahamas platform.
