The oldest rocks in Jamaica are Cretaceous with the succession dominated by andesitic volcanic rocks with associated limestones representing an island arc system. The principal features of the geology of the island are described followed by ten itineraries which illustrate at outcrop the variety of the Cretaceous to Recent rocks including granite-like intrusions, volcanic lavas and altered ashes, mineral deposits, highly fossiliferous limestones and shales, and economically important bauxites. Car hire is recommended.
