The principal objective of this chapter is to present a compilation of original sources of paleomagnetic data for the Caribbean region, as published to the end of 1985. Secondarily, trends in the data and explanations for them are summarized, with emphasis on post-Paleozoic structural-tectonic rotations and paleogeographic implications.
Areal limits for this compilation coincide with the limits of the map of Case and Holcombe (1980): 05Â° to 24Â°N and 054Â° to 093Â°W (Fig. 1). A few studies overlap these boundaries. The focus is on paleomagnetic directional data; therefore, studies of regional continental and oceanic crustal magnetic anomaly trends have been excluded. Some theses and a few abstracts have been included, but works in preparation or in press have been omitted. As the objective of this chapter is to summarize paleomagnetic information, no attempt has been made to evaluate the numerous tectonic scenarios proposed by many authors for the Caribbean. It is hoped that researchers of diverse interests will find the appendix and citations of original data sources useful. The appendix identifies data sources by region: Greater Antilles; Lesser Antilles; Central America; northern South America; and the Caribbean area oceanic basins.
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.
