Metallogenic evolution of the Caribbean region
The principal objective of this review is to illustrate the relation between the mineral deposits of the Caribbean region (Fig. 1, Plate 13) and their geologic and tectonic environment. In areas such as the Caribbean, where regional geological data are scarce, the distribution and composition of mineral deposits provides important information on the location and offset of largescale faults and the continuity and relations between dissected terranes. In addition, because the hydrothermal systems that form many mineral deposits scavenge metals from large volumes of surrounding crust, their metal and isotopic compositions can provide useful insights into the characteristics and sources of these rocks, including deeper, unexposed parts of the crust. To illustrate the relation between mineral deposits and their geologic framework, it is necessary to use a genetic (or modelbased) classification of mineral deposits rather than simply a commodity or element-based system. Readers unfamiliar with the deposit models used here should consult Guilbert and Park (1986) or Jensen and Bateman (1979). Caribbean mineral deposits fit easily into commonly used models, with a few exceptions. The most important of these exceptions are the deposits found in the Cobre Formation of eastern Cuba and the Wagwater belt of Jamaica, which exhibit a close relation to the tectonic evolution of the region, as discussed below. In preparing this review, a strong effort was made to incorporate Cuban mineral deposits, although much of the literature on these deposits lack observations of the type needed to classify the deposits.
Figures & Tables
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.
