“…The orogenic influence on foreland basin strata is well established (e.g., Heller and Paola, 1989;Ross et al, 2005;DeCelles et al, 2009;Horton, 2018). Recent research has hypothesized that the rheology of foreland basin deposits can control the structural evolution of the fold-thrust belt (Chapman and DeCelles, 2015) and that changes in sediment yield may be linked to deformation in the interior of the orogen (Wipple, 2009).…”

“…Aggradation and denudation of proximal foreland basin deposits in the wedge-top depozone are first-order controls on sediment flux to more-distal parts of foreland basin systems (Ben-Avraham and Emery, 1973;DeCelles, 1994;DeCelles and Giles, 1996;Roddaz et al, 2005;Ross et al, 2005;Horton, 2018). Burial of the frontal toe of the orogen can heal complex topography and enhance direct sediment transfer from the orogenic hinterland to a basin.…”

The Late Jurassic to Early Cretaceous fill of the Western Interior foreland basin is characterized using geochronological data in order to assess the stratigraphic expression of wedge-top geomorphology, as controlled by sediment cover and denudation. In northern Montana, USA, and Alberta, Canada, wedge-top deposits are poorly preserved; however, their former presence may be inferred from the detrital record in the foreland basin. We present new U/Pb detrital zircon data from nine samples collected near Great Falls, Montana, augmented with field data. The stratigraphy at Great Falls is characterized by Late Jurassic marine and nonmarine deposits, which are truncated by a basinwide sub-Cretaceous unconformity. Aptian and lower Albian strata overlying the unconformity are dominated by nonmarine deposits, which transition up-section into a predominantly marine succession related to a major transgression of the Boreal Seaway in the Albian.Detrital zircon grains from Great Falls strata yield age spectra that can be subdivided into three groups using multidimensional scaling. Group 1 is characterized by diverse zircon populations, which are interpreted to record recycling of pre-Cordilleran sedimentary strata transported via foreland basin-axial river systems with headwaters in the southwestern United States. Group 2 is characterized by the dominance of Mesozoic detrital zircon grains, which are interpreted to record sediment dispersal by fluvial systems with headwaters in the Cordillera. Group 3 is intermediate between groups 1 and 2, based on its proportion of Mesozoic zircon grains. This group records a diversification of the provenance from one dominated by Cordilleran igneous rocks to include recycled sedimentary strata.New data are integrated with three other data sets from Montana and Alberta such that stratal thicknesses (a proxy for accommodation development) and provenance evolution can be compared across the basin. The detrital record in each area, which transitions from diverse provenance to predominantly Cordilleran through the entire stratigraphic section, can be linked to the burial of the pre-foreland strata in the wedge-top depozone. This record elucidates a period of evolution of the western margin of North America to a more Andean-type system with primary input to the basin from an active magmatic arc.

“…Neogene evolution of retroarc regions involved continued eastward advance of deformation and foreland basin evolution, with large‐scale shortening accommodated in the frontal thrust belt (Subandean/Santa Bárbara zone) and minor shortening across most of the orogenic interior (Barnes et al, , ; Echavarria et al, ; Ege et al, ; Gubbels et al, ; Kley & Monaldi, ; Lamb, ; Lamb & Hoke, ; Lease et al, ; McQuarrie et al, ; Uba et al, ). Basin evolution was concentrated in foreland regions east of the thrust front, with topographically isolated basins in intermontane settings and the hinterland plateau (Capaldi et al, ; Carrapa et al, ; Coutand et al, ; Horton, , , , ; Horton et al, ; Jordan & Alonso, ; Levina et al, ; Mosolf et al, ; Murray et al, ; Sempere et al, ; Siks & Horton, ; Sobel et al, ; Strecker et al, ; Streit et al, ). Stable isotope data and geomorphic surfaces suggest that major surface uplift of the hinterland plateau at 18–22°S was accomplished from middle Miocene to present (Garzione et al, , ; Hoke et al, ; Jordan et al, ), with a possibility of much earlier surface uplift in the Puna plateau at 24–26°S (Canavan et al, ; Quade et al, ).…”

“…Questions emerging from these debates center on whether the Andes behaved uniformly along strike and whether the opposing orogenic flanks acted independently or in unison. These issues can be addressed in studies of forearc and retroarc regions, particularly for sedimentary basins containing long‐lived depositional histories and distinct hiatuses in their stratigraphic records (e.g., Balgord & Carrapa, ; Charrier et al, ; DeCelles et al, ; Hartley & Evenstar, ; Horton, ; Horton et al, , ; Jordan et al, ).…”

Tectonic Regimes of the Central and Southern Andes: Responses to Variations in Plate Coupling During Subduction

Construction of the Andes has been governed largely by fluctuating contractional, neutral, and extensional tectonic regimes during differing degrees of mechanical coupling along the convergent plate boundary. These three contrasting regimes are likely regulated by geodynamic variations in absolute trenchward motion of South America and episodic regional shifts in the geometry of the subducting oceanic slab. Alternations among these three modes are revealed in syntheses of Mesozoic‐Cenozoic crustal deformation, basin evolution, and arc magmatism along orogen‐perpendicular transects across the central and southern Andes at 23°S, 35°S, and 43°S. Despite considerable along‐strike dissimilarities in the magnitude of deformation, a comparable tectonic regime typified the early Andean history, as defined by a transition from Late Jurassic‐Early Cretaceous postrift thermal subsidence to Late Cretaceous retroarc shortening. A key contradiction is expressed for the late middle Eocene to earliest Miocene, when neutral to extensional conditions affected retroarc to forearc regions, except in parts of the central Andes, which experienced retroarc shortening with only localized forearc extension. This mixed‐mode scenario during Paleogene time may reflect decoupling along the plate boundary (possibly during slab rollback within a retreating subduction system) in which widespread stasis or low‐magnitude extension dominated the southern Andes but was inhibited in the strongly shortened central Andes at 15–25°S where shallow subduction and/or high topography boosted plate coupling. Comparable temporal and spatial shifts in tectonic regime along the Andes and other convergent margins can be related to variable degrees of coupling during first‐order plate‐scale changes in convergence and second‐order regional cycles of slab shallowing and steepening.

“…Finally, Cretaceous to Cenozoic rocks of the North Patagonian Cordillera are intimately related to Andean tectonics, with two main Middle‐Late Cretaceous and Miocene orogenic phases (Gianni et al, ; Horton, ; Orts et al, ). In contrast to the Miocene transpressional phase, which is well recorded by structural, kinematic, and geochronologic data of volcano‐sedimentary and granitic rocks (Bechis, Encinas, et al, ; Diraison et al, ; Giacosa et al, , ; Giacosa & Heredia, ; Orts et al, ), the Cretaceous Andean record of the study area is only restricted to few granitoids yielding K‐Ar and Rb‐Sr ages of circa 120–80 Ma (González Díaz, , and references therein).…”

The Late Paleozoic Tectonometamorphic Evolution of Patagonia Revisited: Insights From the Pressure‐Temperature‐Deformation‐Time (P‐T‐D‐t) Path of the Gondwanide Basement of the North Patagonian Cordillera (Argentina)

Combined field structural analysis with in situ electron probe microanalysis Th‐U‐Pb monazite dating, petrologic, and microstructural data provides a reconstruction of the pressure‐temperature‐deformation‐time (P‐T‐D‐t) path of the Gondwanide basement of the North Patagonian Cordillera. For samples from the Challhuaco hill, the timing of development of the metamorphic S2 foliation and associated L2 lineation and tight to isoclinal F2 folds is constrained by monazite ages of 299 ± 8 and 302 ± 16 Ma during peak metamorphic conditions of ~ 650 °C and 11 kbar, achieved during prograde metamorphism and progressive deformation. Metamorphism and deformation of metamorphic complexes of the North Patagonian Andes seem to record Late Paleozoic crustal thickening and are coeval with metamorphism of accretionary complexes exposed further west in Chile, suggesting a coupled Late Devonian‐Carboniferous evolution. Instead of the result of continental collision, the Gondwanide orogeny might thus be essentially linked to transpression due to advancing subduction along the proto‐Pacific margin of Gondwana. On the other hand, second generation of monazite ages of 171 ± 9 and 170 ± 7 Ma constrains the timing of low‐grade metamorphism related to kink band and F3 open fold development during Jurassic transtension and emplacement of granitoids. Finally, a Cretaceous overprint, likely resulting from hydrothermal processes, is recorded by monazite ages of 110 ± 10 and 80 ± 20 Ma, which might be coeval with deformation along low‐grade shear zones during the onset of Andean transpression.
