Abstract
Los nuevos datos de sísmica de reflexión multicanal 2D adquiridos en la Cuenca de San Pedro (margen sudeste de la República Dominicana), junto con antiguos perfiles sísmicos reprocesados, han permitido llevar a cabo un detallado análisis y revisión de la estratigrafía sísmica. Los nuevos datos sísmicos aportan nuevas precisiones sobre la evolución de la cuenca sugiriendo un origen de al menos Eoceno Superior, en lugar de Mioceno. La nueva interpretación se basa en la correlación onshore-offshore de un nivel guía de abanicos bien desarrollado, con los eventos tectónicos constreñidos tierra y asociados a la colisión con los Bancos de las Bahamas con el arco isla el Eoceno Medio.
New 2D multichannel seismic reflection data recorded in the San Pedro Basin (south-eastern margin of Dominican Republic,) combined with vintage seismic reflection profiles, have allowed a detailed analysis and review of the seismic stratigraphy. New data supply new constraints on the evolution of the basin and suggest at least an Upper Eocene origin instead of Miocene. The new interpretation is based on the onshore-offshore correlation of fan deposits with the main tectonic events constrained onshore and related with the collision of the Bahamas banks with the island arc in Middle Eocene ages.
