| Resumen: |
Lumpy limestones with reelaborated ammonites are a typical facies in the Lower Pliensbachian of the Lusitanian Basin. They were developed in deep marine environments, induced by sedimentary starving. Reelaborated ammonites, with various taphonomic attributes, provide a key to recognition of condensed deposits developed in deep offshore environments during intervals of low sediment input. [RÉSUMÉ]: Les calcaires grumeleux avec des ammonites réélaborées, correspondent a un facies très typique dans le Pliensbachien inférieur du Bassin Lusitanien. Ils se sont développés en milieu marin profond, sur conditions de bas taux de sédimentation. Ces ammonites réélaborées, avec des différents attributs taphonomiques, sont un moyen important pour la reconnaissance de dépôts condensées en milieu marin profond. |
