EGUILUZ DE ANTUNANO, Samuel. Berriasian-Aptian stratigraphic sequences in the Sabinas Basin: its meaning in the understanding of the geological evolution of Northeastern Mexico. Bol. Soc. Geol. Mex [online]. 2011, vol.63, n.2, pp. 285-311. ISSN 1405-3322.

Berriasian-Aptian stratigraphic sections of the Sabinas Basin, northeastMéxico, show three major unconformities as second order sequence boundaries. Every sequence includes transgressive-regressive tracts and a máximum flooding zone. From the Chihuahua Basin to the Tampico Basin there are transgressive-regressive tracts placed at the same age and stratigraphic level, which are correlative to the Sabinas sections. The previous sequence boundaries may have a subordinate tectonic component, but sequence analysis indicates that these sequences are due to variations mostly linked to eustatic changes in sea level globally, as mentioned by other authors.
