Within the stratigraphic column, overlieswith sharp contact the continental deposits of the Tordillo and QuebradadelSapo formations denoting the Tithonian transgression.

* Stage 1. Late Triassic-Early Jurassic: prior to the onset of subduction on its western margin, this part of Gondwana was characterized by large transcurrent fault systems. This led to extensional tectonics whitin the basin and the evolution of a series of narrow, isolated depocentres (Fig. 2).<ref>Manceda, R., & D.

* Stage 2. Early Jurassic-Early Cretaceous: development of a steeply dipping, active subduction zone and the associated evolution of a magmatic arc along the western margin of Gondwana led to back-arc subsidence within the Neuquén Basin. This post-rift stage of basin development locally accounts for more tan 4000 meters of the basin fill (Fig. 2) (Vergani et al. 1995).
