Geomorphic evidence for Plio-Quaternary compression in the Andean foothills of the southern Neuquén Basin, Argentina

The southern central Andes foothills are made of imbricate thick‐ and thin‐skinned fold and thrust belts. They were formed during Cretaceous and Miocene compressive periods by successive eastward propagation episodes of the orogenic front. We analyze remnant terraces and alluvial deposits of the Neuquén River and its tributaries to study the Plio‐Quaternary tectonic regime in the southern Neuquén Basin. Topographic profiles of remnant terraces show a crustal‐scale (tens of kilometers) anomaly above the Chihuido South anticline. This anomaly is accompanied by sedimentary aggradations downstream and upstream of the anticline. Another anomaly in the terrace profiles, correlated with a knickpoint in the current Neuquén River, is observed farther east, near Añelo. We interpret these anomalies to be the consequence of a Plio‐Quaternary uplift of the Chihuidos and Añelo anticlines. Folding and surface faulting of Plio‐Quaternary alluvial deposits show that this uplift is concomitant with the reactivation of the Miocene orogenic front and of the predominantly thin‐skinned Agrio fold‐and‐thrust belt. From these data we infer that the southern Neuquén Basin is still shortening under a compressive stress regime and that the Andean orogenic front is migrating farther to the east. Extensional features in the study area correspond mainly to thin‐skinned gravitational gliding, resulting from crustal uplift. Thus, we argue that the tectonic compressive regime is preserved in the southern Neuquén Basin throughout the Plio‐Quaternary, though the slab may have steepened during this period.

Abstract. We reconstruct the main geological structures and surfaces in three dimensions through the interpolation of regularly spaced 2D seismic sections, constrained by wells data and surface geology of the Qaidam basin to 15 reconstruct Cenozoic tectonic history of the Qaidam basin and decipher how the Tibetan plateau was formed. This study presents the subsurface data in conjunction with observations and analysis of the stratigraphic and sedimentary evolution. The Cenozoic deformation history of the Qaidam basin shows geologic synchroneity with uplifting history of the Tibet Plateau. It is therefore proposed that the deformation and uplifting in the south and north edges of the Tibet Plateau was almost synchronous. The total shortening and shortening rate during Cenozoic reached 25.5 km 20 and 11.2% respectively across the Qaidam basin, indicating that the loss of the left-lateral strike slip rates of the Altyn Tagh fault has been structurally transformed into local crustal thickening across NW-trending folds and thrust faults.Meanwhile there is an about 10° vertical component along the strike-slip Altyn Tagh fault, the block oblique slip shows one more growth mechanism of the northeast Tibet.

“…Detailed structural works at this region are scarce and they are restricted to specific sites associated with important oil fields near the Andean thrust front (e.g. Ploszkiewicz and Viñes, 1987;Zapata et al, 2001;Allmendinger et al, 2004;Zamora Valcarce et al, 2006b). Despite of the petroliferous interest of the whole area, the published structural cross-sections of the Chos Malal FTB are very regional (Ramos and Barbieri, 1988;Both and Coward, 1996;Chaveau et al, 1996;Kozlowski et al, 1996;Cobbold et al, 1999;Zapata et al, 1999;Folguera et al, 2007Rojas Vera et al, 2014), focused on the major thrusts affecting basement blocks.…”
