Sedimentación sintectónica de la Formación El Castellar (Cretácico Inferior) en la Subcuenca de Galve (Cuenca Ibérica)

Abstract

The sedimentary record o f El Castellar Fm. in the Calve subbasin has been divided into two stages according to the presence of a mudstone and gypsum interval. This interval represents a paleogeographic and structural significative change. The geometry and facies distribution were controlled by extensional faults. However, the first stage shows a great variety of subenvironments and facies, while the second stage is characterized by an extensive hard water lake. These evidences has been interpreted as the result of the independent movement o f the faults during the first stage and the movement o f the whole extensional faults on a sole detachment during the second stage.
