The result of a major international effort involving authors and organizations from 13 countries, this volume summarizes the complex geology and tectonic evolution of the Caribbean plate and its relation to the adjacent North American, South American, Nazca, and Cocos plates. Focuses on regional geology and geophysics, magmatic processes, neotectonic features, geologic hazards, and energy and metallic resources. Contrasting views for the Mesozoic and Cenozoic geological evolution are presented in chapters on plate tectonics and mantle surge tectonics. Chapters on marine geology and geophysics are new syntheses for the entire Caribbean region. Highlights of the volume include extensive bibliographies and new syntheses of stratigraphic-lithologic columnar sections, seismicity, gravity and magnetic anomalies, neotectonic features, resource data, and crustal properties.

Abstract

The Caribbean area has a rich and varied igneous history, especially in the Late Cretaceous and Cenozoic. The emphasis of this chapter will be on that portion of the igneous history that began with Mesozoic separation of South and North America and has continued to the Holocene. Pre-Jurassic magmatism is recorded in northern Central America, Venezuela, and Colombia, and will be discussed briefly in other chapters of this volume. The aim of this chapter will be to describe igneous rock associations according to magmatic styles that characterize certain time intervals of the Caribbean and to suggest how these styles relate to contemporary tectonics. A recurring theme will be the close relationship among widespread igneous rock occurrences which might have prompted special interpretations in the past. Because the volcanic units that form the backbone of this account are mainly named stratigraphic units, much of this account will refer to these units. Further discussion may be found in other chapters of this volume.
