Abstract

The Villanueva de Huerva Formation in the Aguilón sub-basin (NE Spain) is a Valanginian-lower Hauterivian synrift unit that includes a cyclical interval with 88 lacustrine deepening-shallowing sequences controlled by the orbital precession cycle. The main component in the carbonate facies is dolomite. Textural features suggest a primary origin probably induced by microbial action in a brackish lacustrine system under arid conditions. There are numerous slump levels, and other soft sediment deformation structures, that are located preferentially in the thickest sedimentary cycles and have been related to the unstabilization of basin sediments, due to tilting in the rollover anticline linked to the discontinuous movement of the main fault.
