“…The volcanic activity was coeval with the Nazas arc activity and The continental redbeds assigned to the upper part of La Boca Formation were deposited probably during a period of crustal extension that followed the Early Jurassic magmatic arc activity (Fastovsky et al, 2005;Barboza-Gudiño et al, 2008), or in a back-arc setting related to the Nazas arc. As previously mentioned, the interlayered volcanic rocks yielded an age of 189.0 ± 0.2 Ma (U-Pb, zircon) in the Huizachal Valley (Fastovsky et al, 2005) and a 193 ± 0.2 Ma U-Pb zircon age for an ignimbrite of the Aramberri area.…”

“…These volcanic rocks were assigned to the Late Triassic-Lower Jurassic volcanic arc, related to the active continental margin of western North America (Blickwede, 2001;López-Infanzón, 1986, Grajales-Nishimura et al, 1992Jones et al, 1995;Bartolini, 1998;Bartolini et al, 2003;Barboza-Gudiño et al, 1998, 1999, 2004. The type locality of the Nazas Formation, as defined by Pantoja-Alor (1972) is the Cerritos Colorados area west of Villa Juarez, in northern Durango.…”

“…In western San Luis Potosí, volcanic successions including andesitic and dacitic lava flows and volcanic breccias, as well as rhyolitic domes and ash flow tuffs, are exposed in the Sierra de Catorce, Charcas and Sierra de Salinas or La Ballena area, they rest on Triassic turbiditic layers of the Zacatecas Formation or local in Real de Catorce, on the marginal marine beds of the Lower Jurassic informal unit "Capas Cerro El Mazo" (Barboza-Gudiño et al, 2004). The Capas Cerro el Mazo unit consists of conglomeratic sandstone and medium-to coarsegrained litharenites with fragments of plants, and gray to green and red to purple siltstone and mudstone layers interfingered with volcanic greenstones at the base of the Nazas Formation, which include dacitic and rhyolitic pyroclastic and porphyritic rocks.…”

“…Petrographic studies indicate a recycled orogen and continental block provenance. Barboza-Gudiño et al (2004) reported U-Pb isotopic analyses of zircon for a rhyolite in the upper part of the succession of the Sierra de Catorce, yielded an age of 174.7 ± 1.3 Ma.…”

“…1b), in tectonic contact with small lenses of serpentinite and talc bodies. In all parts these units are overlain by Early Jurassic volcanic rocks, Early-Late Jurassic rift, drift and passive margin sediments related to the opening of the Gulf of Mexico basin [39][40][41][42][43]. The metamorphic age of the Granjeno Schist rocks of the Huizachal-Peregrina anticlinorium has been investigated in several studies.…”

Abstract:The Granjeno Schist is a meta-volcanosedimentary upper Paleozoic complex in northeastern Mexico. We suggest different tectonic settings for metamorphism of its serpentinite and talc-bearing rocks based on petrographic and geochemical compositions. According to the REE ratios (La N /Yb N = 0.51-20.0 and La N /Sm N = 0.72-9.1) and the enrichment in the highly incompatible elements Cs (0.1 ppm), U (2.8 ppm), and Zr (60 ppm) as well as depletion in Ba (1 -15 ppm), Sr (1 -184 ppm), Pb (0.1 -14 ppm), and Ce (0.1 -1.9 ppm) the rocks have mid-ocean ridge and subduction zones characteristics. The serpentinite contains Al-chromite, ferrian chromite and magnetite. The Al-chromite is characterized by Cr# of 0.48 to 0.55 suggesting a MORB origin, and Cr# of 0.93 to 1.00 for the ferrian chromite indicates a prograde metamorphism. We propose at least two serpentinization stages of lithospheric mantle for the ultramafic rock of the Granjeno Schist, (1) a first in an ocean-floor environment at sub-greenschist to greenschist facies conditions and (2) later a serpentinization phase related to the progressive replacement of spinel by ferrian chromite and magnetite at greenschist to low amphibolite facies conditions during regional metamorphism. The second serpentinization phase took place in an active continental margin during the Pennsylvanian. We propose that the origin of the ultramafic rocks is related to an obduction and accretional event at the western margin of Pangea.

Magmatic source and metamorphic grade of metavolcanic rocks from the Granjeno Schist: was northeastern Mexico a part of Pangaea?

The geochemistry of the metavolcanic rocks from the Granjeno Schist in northeastern Mexico indicates an origin in different tectonic environments: mid‐ocean ridge and ocean island. High ratios of Hf/Th and Th/Nb (4.4–14 and 0.08–0.15), low ratios of LaN/YbN and LaN/SmN (0.74–1.7 and 0.60–1.4) and depleted LREE patterns in metabasalt display mid‐ocean ridge characteristics. In contrast, the pattern of trace‐element ratios and REEs in metabasalt and metapillow lava 60 km to the west indicates a magma source with ocean‐island basalt characteristics. Both areas were metamorphosed during the Late Carboniferous (300 ± 4 Ma). Estimated metamorphic conditions deduced from white mica and chlorite compositions, distinguish greenschist facies (350 °C and 4 kbar) for the mid‐ocean ridge basalt, and prehnite–pumpellyite facies (250 °C and 2.5 kbar) for the ocean‐island‐type basalt. This metamorphism took place at an active continental margin during Pennsylvanian time. Our new tectonic model, which differs from earlier models, suggests that the origin of the Granjeno Schist is related to a subduction zone located at the western margin of Pangaea, active after Laurentia–Gondwana collision.
