Estudio de la estructura de la Cuenca de Almazán a partir de datos geofísicos

Abstract

A combined analysis of two different geophysic sources (seismic profiles and Gravity Anomaly Map), has been worked out in the Almazán Basin. A top Albian isobath map has been drawn through restitution of seismic reflexion profiles. A gravity survey, covering an area of 8000 Km2, has been carried out obtaining a Gravity Anomaly Map. The study of the Gravity Anomaly Map shows that Gravity Anomaly distributions are due to superficial structures, seated in the basin filling and deeper structures, seated in the basement. The.gravity modelling of three profiles supported on wells, seismic and geologic data allows us to suggest the existence of three different bodies in the basement
