The birth of the Caribbean Geological Conference in 1955 was a landmark in the search for geoscientific knowledge in the region. The proceedings of this conference continue to uncover many aspects of the Caribbean that remain virtually untouched and address questions that remain unanswered. This volume reports the most recent research on Caribbean geology, presented at the Fifteenth Caribbean Geological Conference held in 1998. The 24 research papers shed new light in the areas of plate tectonics, structural geology, metamorphic and igneous petrology, paleontology, biostratigraphy, economic geology, geochemistry, mineralogy, geologic hazards and geoscience education.
