Character of the Caribbean Crust Revealed: Initial Observations of New and Reprocessed Seismic Data

Abstract

Details of the tectono-sedimentary evolution of the Caribbean region are debated due to lack of modern and regional seismic data. We present data in support of distinct tectonic provinces and regional stratigraphic suites that reveal the complex evolution of the Caribbean Plate. In this study we use a Caribbean-wide 3,500+ km composite seismic line that extends from offshore Panama to the Barbados Accretionary Prism over-riding the Central Atlantic Plate. Sharp boundaries along tectonic provinces and structured regions correlate to anomalous zones in the filtered magnetic data and allow for tentative mapping of regional features beyond the seismic control.
