“…The model results presented explore the influence of the Laramide shortening advance on the gravity-driven salt system, and particularly on the diversity of extensional and shortening structures. The Laramide orogeny was a regional event of east directed shortening deformation which affected northeastern Mexico during Late Cretaceous-middle Eocene time span (80 to 35 Ma; Ye, 1997;Eguiluz de Antuñano et al, 2000;2004;Chávez Cabello et al, 2011). In the southernmost part of the saline domain, the structural linked systems are closer to the Laramide orogenic that reached the Burgos Basin area (Pérez-Cruz, 1992;Eguiluz de Antuñano, 2004;2009;Chávez Cabello et al, 2011).…”

In the deep seated gravity-driven deformation systems of the Gulf of Mexico contemporaneous extension and contraction of the overburden is favored by mechanical decoupling from the basement along thick salt sequences (up to 4 km). The updip extension is located inland, on the continental shelf of northeast Mexico, and is characterized by extensional listric faults and roll-overs; the downdip shortening zone is located at the deep waters and is characterized by a fold and thrust belt detached above the salt layer. Two physical experiments are used to discuss some aspects of these gravity-driven systems. The experimental setup includes a motor-driven experimental table, an inclined brittle basement (1°), a silicone layer simulating the salt sequences, and sand layers simulating the pre-kinematic Jurassic-Cretaceous strata before Laramide shortening. Deformation resulted in further tilting of the basement (3° to 4°). After the onset of deformation, thin sand layers were added at regular time intervals simulating the syntectonic sedimentation. The experiments reproduced the geometry of the deformation at the frontal ramp characterized by a seaward vergent thrust and its associated deformed region (the Perdido fold belt). The fold and thrust belt localization was favored by the change in basement inclination (a built-in slope change). Key elements interpreted in one available section of the area were reproduced in the model: a) the presence of an antithethic roll-over in the extensional zone and, b) the basinward vergence of folds and thrusts observed in the downdip shortening zone in the mexican Perdido fold belt.

“…Both localities are linearly separated by 140 km. If tectonic shortening is omitted, which is estimated at least in 37% at the Santa Rosa canyon, Nuevo León (Chávez-Cabello et al, 2011), and in 33% between Monterrey and Aramberri (Eguiluz de Antuñano et al, 2000), then this area used to be larger than the actual size. These results confirm the general observation that peritidal sequences are mostly present in the platform interior ( Figures 10 and 11).…”

Depositional episodes are readily identified along representative localities of the Lower Cretaceous Cupido platform in northeastern Mexico. The basal part of the Cupido Formation exhibits a progradational reef platform that, at the upper limit, is truncated by a sequence boundary defined by a breccia. This breccia marks the development of a peculiar sedimentary facies informally known as the Cupidito unit, a distinctive stratigraphical unit in northeastern Mexico that remained uninterpreted for decades. Through the analysis of facies, microfacies and stable isotope comparisons from representative localities (Potrero Chico, Potrero de García, La Huasteca, La Muralla and Puerto Mexico) and from other previously reported outcrops, this work describes six diagnostic features for Cupidito and an improved stratigraphic model is proposed. The depositional sequence suggests a broad flat-topped platform with a general low organic productivity and restricted conditions followed by recurrent inundations of lagoon waters. Before drowning, this carbonate platform remained under equilibrium conditions interrupted by short pulses of relative higher-temperatures (48.3 °C and 39.2 °C). Coral-rudist-stromatoporoid patch-reefs with inferred inter-tropical temperatures between 31.5 °C and 32.2 °C originated as a progradational response to the instauration of a new Sequence Boundary at the base of Cupidito.
