Description / Table of Contents:
This book considers the geology between North and South America. It contributes to debate about the area's evolution, particularly that of the Caribbean. Prevailing understanding is that the Caribbean formed inthe Pacific and was engulfed between the Americas as the latter drifted west. Accordingly, the CaribbeanPlate comprises internal, Jurassic-Cretaceous oceanic rocks, thickened into a Cretaceous hotspot/plumeplateau, with obducted ophiolites and Cretaceous-Palaeogene, subduction-related, intra-oceanic volcanicarc and metamorphosed arc/continental rocks exposed on its margins. An alternative interpretation is thatthe Caribbean evolved in place. It consists largely of continental crust, extended in the Triassic-Jurassic,which subsided below thick Jurassic-Cretaceous carbonate rocks and flood basalts, and Cenozoic carbonateand clastic rocks. After uplift of 'oceanic' and volcanic arc rocks onto (continental) margins, the interiorfoundered in the Middle Eocene. Papers range from regional overviews and discussions of Caribbeanorigins to aspects of local geology arranged in a circum-Caribbean tour and ending in the interior. They address tectonics, structure, geochronology, seismicity, igneous and metamorphic petrology, metamorphism, geochemistry, stratigraphy and palaeontology.
