“…Late Cretaceous lithospheric thickening and shortening caused flexural loading across the attenuated South American plate, which is recorded by Upper Cretaceous siliciclastic basin infill (Figure 1) within an axial foredeep (Bernhard et al., 2012; Biddle et al., 1986; Fildani et al., 2003; Malkowski et al., 2016; Rivera, 2017; Romans et al., 2011; Sickmann et al., 2019).

Tectonic Subsidence Modeling of Diachronous Transition From Backarc to Retroarc Basin Development and Uplift During Cordilleran Orogenesis, Patagonian‐Fuegian Andes

The distribution of depositional environments along continental margins and ocean basins is primarily controlled by tectonics, lithospheric type and thickness, eustasy, and climate (e.g., Browning et al., 2006;Collins et al., 1996;Ghiglione et al., 2008). Consequently, it can be difficult to resolve the relative impact of these factors and their interactions, particularly in active basin settings. In foreland basins, transgressions resulting from eustatic sea level rise can be misinterpreted as phases of basin deepening from tectonic loading, and vice versa (e.g., Horton et al., 2004). In extensional basins, the timing and duration of synrift faulting and subsequent postrift cooling generate predictable patterns of basin subsidence that may progress along the basin depocenter(s) differently owing to rift geometry and kinematics (e.g.,

“…Structural syntaxes controlling axial sediment routing systems are documented globally. For example in the Cenozoic Austral/Malvinas basins of southern Argentina, thick turbidite sequences were deposited axially along an east–west foreland basin system, which is largely controlled by the Tierra del Fuego to the west and the fold‐thrust belt system to the south (Carbonell & Olivero, 2008, 2012, 2019; Olivero & Carbonell, 2020).…”

Challenging assumptions of sediment routing in retroarc foreland basins: Detrital zircon evidence for axial versus transverse drainages in the Late Cretaceous of southern Utah, USA

Depositional models for retroarc foreland basin systems commonly imply a direct link between thrust belt dynamics and sediment supply, despite documented complexity between orogen‐transverse and orogen‐parallel (axial) sediment routing systems. Previous detrital zircon provenance studies from the Straight Cliffs Formation in the Kaiparowits Plateau of southern Utah indicate primary axial source areas to the south (Mogollon Highlands), and southwest (Cordilleran magmatic arc), with relatively minor transverse input from the Sevier fold‐thrust belt to the west. Complementary data from 32 new samples are presented to investigate whether these trends persist in correlated strata from sections most proximal to the active fold‐thrust belt, as well as strata proximal to the Mogollon Highlands. This study aims to improve statistical robustness through higher‐n datasets (>300 analyses/sample) and addresses the possibility of recycling of zircon grains from strata in the exhumed Sevier fold‐thrust belt. Based on this provenance dataset, we infer that orogen‐transverse deposition was mainly limited to the most proximal sections (within ca. 75 km of the fold‐thrust belt), but included episodic distribution across the foredeep that was associated with distinct intervals of widespread amalgamated sand and gravel sheet deposits. In contrast, more distal parts of the foredeep record long‐distance fluvial transport (>400 km) of zircons from the active Cordilleran magmatic arc as well as Yavapai‐Mazatzal basement rocks in central Arizona (the Mogollon Highlands). Palaeogeographic reconstructions suggest the apex of a large basin‐axial fluvial system may have been located at the structural syntaxis between the Sevier fold‐thrust belt and western margin of the Mogollon Highlands. This interpretation is supported by detrital zircon data presented here, thus extending the possibility that the Palaeogene ‘California River’ may have existed by at least Late Cretaceous time. Ultimately, these data point to extrabasinal controls on sediment supply, which was largely decoupled from flexural accommodation controls in this archetype retroarc foreland basin.

“…The Huai Lat Formation consists of facies A1, A2, and B1. This formation represents the main upper channel or major channel fill complexes, probably in the most proximal depositional areas [ 30 , 31 , 32 , 33 ]. Facies A1 is matrix-supported (sand sized), pebble-cobble massive conglomerate, and its basal contact is erosive.…”

Basin classification and tectonic framework of the Nam Pat Group, Uttaradit Province, Thailand: Implications for the Nan Suture Zone

The Nam Pat Group of the Nam Pat Basin, Uttaradit Province, Thailand is situated in the Nan Suture Zone. Two contrasting tectonic framework models of the Nan Suture have previously been proposed: as a main Paleo-Tethyan suture and as a remnant of a closed back-arc basin. The goal of this study is to analyze the tectonic framework of the Nan Suture and reevaluate the existing tectonic models. This research infers the tectonic setting of the basin based on basin-filled lithofacies distributions, provenance, and paleocurrents. Three facies groups are identified. Facies A, B, and C are polymictic conglomerate, interbedded sandstone and mudstone, and mudstone with thin-bedded sandstone, respectively. Generally, the strata strike NE-SW, steeply dip NW, and fine toward the SE. Petrographic results of sandstone samples show that the majority of lithic fragments are volcanic rocks with lesser amount of metamorphic rocks and sedimentary rocks. The modal compositions of sandstones are analyzed on QFL, QmFLt, QmPK, LmLvLs, and QpLvmLsm ternary diagrams. The plots indicate that the sandstones of the Nam Pat Group have high proportions of volcanic-arc detritus. Paleocurrents, determined from the orientation of clast imbrications and cross-stratification, are toward the SE. The results suggest that large quantities of sediment traveled southeastward from a nearby volcanic arc into the basin. The Nam Pat Group stratigraphically overlies the Pak Pat Volcanics. The chemical features of the Pak Pat Volcanics, located to the west of the basin, show that they are andesitic volcanic rocks formed as a magmatic arc. Thus, the nearby Pak Pat Volcanics are the main sediment source of the Nam Pat Group, and the basin is best interpreted as back-arc basin rather than as a forearc basin.
