Abstract
A coastal siliciclastic unit was deposited during the Aptian at the base ofVillarroya de los Pinares Formation in Las Parras sub-basin. It can be subdivided in four coarsening-upwards coastal sequences. We focus in the third sequence (S3), which is built up of fine to coarse sandstones, representing an upward change from storm dominated lower shoreface to upper shoreface environments. This sequence represent a reliable datum for correlation across the study area, allowing enhanced stratigraphic precision and the recognition of interesting relationships in the siliciclastic unit. Its lateral facies change suggests the location of a clastic discharge system toward the southeast. The major thickness unhomogeneity across this sequence is also found at the south- easternmost section, which is related with a different structural location involving a jump towards another subsiding block.
