• Resumen

  • 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 of the faults during the first stage and the movement of the whole extensional faults on a sole detachment during the second stage.
