Regional Geological/Geophysical Study of the Caribbean Sea (Navy Ocean Area NA-9). 1. Geophysical Maps of the Eastern Caribbean.
Abstract
A series of seven geophysical maps and three track control maps has been compiled for the eastern Caribbean Sea. These maps are based upon bathymetric, magnetic, and seismic data from all available sources, and are estimated to contain between 90 and 95 percent of all data in existence for the Venezuela Basin. A comparison of the seismic maps with the bathymetric map indicates that eastern Caribbean bathymetry is primarily controlled by structure. Sedimentary processes have tended to subdue the structural expression by partially filling depressions. The geomagnetic map shows generally low relief resulting from the low magnetic latitude of the mapped area. High amplitude, short-wavelength anomalies are associated with igneous activity along the island chains and the Aves Ridge. Interpretations are limited, with emphasis placed on criteria used for compilation of the maps. References to the open literature have been cited in sufficient number to provide a general reading guide for further study. (Author)
