Abstract
Se describen cuatro discontinuidades con desarrollo de valles incisos de entre 10 y 73 metros de profundidad. La superficie S3 que presenta el mayor encajamiento puede correlacionarse a escala global con el límite de secuencia Ap4, y probablemente representa una oscilación eustática. Nuestros resultados apoyan la presencia de hielo polar durante el Aptiense.
Four unconformities with incised-valley development are described from the Aptian of the Galve sub-basin. Incision magnitude varies from 10 to 73 metres. The deepest incision correlates well with Ap4 sequence boundary of Hardenbol et al., (1998), and probably represents a high amplitude eustatic fall. Our results support the presence of polar ice-caps during the Aptian
