“…420-410 Ma population observed in the Black Warrior basin. The Maya Mountains also expose Late Silurian plutons of compatible age (Steiner and Walker, 1996;Martens et al, 2010), and the Maya block has been interpreted to be located near bi-modal rift-drift, backarc, and arc tectonism (Casas-Peña et al, 2021) that is compatible with the variable Th/U values observed in Black Warrior strata. The Yucatan/Maya block has been proposed as a source of ca.…”

Detrital zircon geothermochronology reveals pre-Alleghanian exhumation of regional Mississippian sediment sources in the southern Appalachian Valley and Ridge Province

et al. 2021

The Black Warrior foreland basin records sedimentation associated with the development of intersecting Ouachita and Alleghanian thrust belts along the southern margin of Laurentia. Mississippian–Pennsylvanian units in the Black Warrior basin are interpreted to be sourced from either the northern Appalachians and mid-continent or more regionally from the southern Appalachians or nearby Ouachita thrust belt. We present detrital zircon U-Pb ages and Th/U values from Paleozoic units that indicate zircon from the Mississippian Hartselle Sandstone are temporally and chemically compatible with being sourced from the southern Appalachians. Zircon mixing models suggest sediment was primarily recycled from Cambrian, Ordovician, and Devonian strata in the Appalachian Valley and Ridge, with minor influx from Piedmont units. A ca. 415 Ma zircon population requires additional input from the Maya Block of the Yucatan Peninsula or similar outboard terranes. We present zircon (U-Th)/He analysis and thermal history modeling of Paleozoic units, which detail pre-Alleghanian exhumation in the Appalachian Valley and Ridge. Both the Cambrian Chilhowee Group and Pennsylvanian Pottsville Formation exhibit (U-Th)/He dates ranging from 507 to 263 Ma with a Mississippian subset (353–329 Ma, n = 4), which indicates rapid cooling and inferred exhumation during Late Devonian–Early Mississippian Neoacadian tectonism. We propose a Mississippian drainage system that transported material along southern Appalachian structural fabrics to the juncture between Appalachian and Ouachita thrust belts followed by a sediment-routing rotation toward the Black Warrior foreland. This interpretation honors chemical-age zircon data, accounts for metamorphic grains in thin section petrography, and matches Mississippian–Pennsylvanian Black Warrior foreland lithostratigraphic relationships.

“…2400 Ma and another at ca. 240 Ma (Casas‐Pena et al, 2021). Thus, all pre‐360 Ma grains in the Huizachal Group sandstone could have come from rocks that are exposed within 10 km of the studied outcrops near Ciudad Victoria and are known or presumed to underlie the outcrops near Aramberri and Galeana.…”

“…There are two possible local sources for this detritus. One is several units of the Tamatan Group: the 350–340 Ma Aserradero Rhyolite and the Guacamaya Formation, which yielded multiple detrital zircon grains with 206 Pb/ 238 U dates between 335 and 320 Ma (Casas‐Pena et al, 2021; Ramirez‐Fernandez et al, 2021). The second possibility is the East Mexico Arc and Anatectite.…”

“…Unmetamorphosed Palaeozoic sedimentary and volcanic deposits overlie the eastern side of the Novillo Metamorphic Complex (Carrillo-Bravo, 1959;Girty, 1926;Maldonado-Koerdell, 1954;Muir, 1936). These strata, termed the Tamatan Siliciclastic Sequence by Aleman-Gallardo, Ramirez-Fernandez, Rodriguez-Diaz, et al (2019) and the Tamatan Group by Casas-Pena et al ( 2021), comprise the following formations and lithologies (Casas-Pena et al, 2021;Ramirez-Fernandez et al, 2021;Stewart et al, 1999). ( 1 Two other rock suites that could have contributed sediment to the Mesozoic deposits belong to the Carboniferous-Triassic East Mexico Arc and a spatially superimposed belt of anatectic granitoid.…”

Provenance and maximum depositional ages of Upper Triassic and Jurassic sandstone, north‐eastern Mexico

et al. 2022

Upper Triassic to lowest Upper Jurassic strata in north‐eastern Mexico record surface processes during the early rifting that led to the opening of the Gulf of Mexico. Exposed near Ciudad Victoria, Tamaulipas and northwest to Galeana, Nuevo Leon, these continental deposits are called the Huizachal Group. Several key questions about these strata hamper their integration into a regional understanding of Late Triassic and Jurassic sediment routing and deposition. First, the depositional age of the stratigraphically lowest unit, the El Alamar Formation, is less well established than the depositional ages of the stratigraphically higher parts of the succession, leading to questions about the timinig of the onset of tectonic context, and regional correlation of these strata. Second, better knowledge of provenance and sediment routing, including fluvial transport distance, can help determine whether and when the depositional basin was split into subbasins versus connected by a throughgoing river system. This study uses sandstone detrital zircon U‐Pb isotopic ages and clast compositions to constrain depositional ages and reconstruct tectonic setting and provenance. Detrital zircon U‐Pb ages yielded a maximum depositional age of 210 Ma for the part of the El Alamar Formation exposed near Galeana, younger than previously determined. Although long‐distance (>100 km) sediment transport cannot be ruled out, the sources for Huizachal Group sandstone framework grains and detrital zircon could have been entirely local, within about 100 km. Alluvial deposits and pyroclastic and lava flows likewise indicate transport of no more than 100 km. We therefore infer deposition in partitioned rift basins receiving sediment from local sources. These data and interpretations contribute to understanding surface processes during the initial rifting that eventually led to opening of the Gulf of Mexico.

“…Another option is that these Ordovician to Devonian zircons come from the Carboniferous Santiago Formation from Oaxaca that contains two clusters, one of 480-450 Ma (peak at 471) and another of 365-335 Ma (peak at 358 Ma) (Gillis, Gehrels, Ruiz, & de Dios González, 2005). Recently, Casas-Peña et al (2021) report a peak at ~426 Ma in detrital zircon grains from sandstones from the Cañ on de Caballeros Fm. of the Tamatán Group of the Ciudad Victoria Block, which can also represent a source.…”

Hermenegildo-Ruiz, and Madhavaraju (2020) it is possible to track a wide-ranging record of the most important magmatic and tectonothermal events preserved along NE to SE of Mexico. These zircon-forming events include those responsible for the development of its Proterozoic basement, the Palaeozoic and Mesozoic magmatic arcs, as well as the Cenozoic arc and intraplate magmatism. The proposed sources for the studied zircon crystals are Oaxaquia, Maya Block, the Peregrina-Mochonian arc, the Tamatán Group of the Ciudad Victoria Block, the Nazas Arc, the Cretaceous Mexican Arc, the foreland basins of the Sierra Madre Oriental, the Eastern Alkaline Province, and the Trans-Mexican Volcanic Belt.
