Journal ArticleDOI
Evidence for an Ordovician continental arc in the pre-Mesozoic basement of the Huizachal–Peregrina Anticlinorium, Sierra Madre Oriental, Mexico: Peregrina Tonalite
Eduardo Alejandro Alemán-Gallardo,Juan Alonso Ramírez-Fernández,Augusto Antonio Rodríguez-Díaz,Fernando Velasco-Tapia,Uwe Jenchen,Esther María Cruz-Gámez,Lorena De León-Barragán,Ignacio Navarro de León +7 more
TL;DR: The Peregrina Tonalite (PTo) is an orphaned block associated with an enigmatic Carboniferous magmatic arc located along the north-western margin of Gondwana as discussed by the authors.
Journal ArticleDOI
Mantle Xenoliths and Their Host Magmas in the Eastern Alkaline Province, Northeast Mexico
Adalberto Treviño-Cazares,Juan Alonso Ramírez-Fernández,Fernando Velasco-Tapia,Pedro Rodríguez-Saavedra +3 more
TL;DR: In this article, a partial melting model for REE was used to identify the source of mafic magnetites in the garnet P-T stability field, which was supported by an enrichment in light REE ([La/Yb]N = 10.8-27.1; chondrite-normalized ratios) and the behavior of relatively immobile trace elements.
Journal ArticleDOI
Provenance and tectonic setting of the Paleozoic Tamatán Group, NE Mexico: Implications for the closure of the Rheic Ocean
Juan Moisés Casas-Peña,Juan Alonso Ramírez-Fernández,Fernando Velasco-Tapia,Eduardo Alejandro Alemán-Gallardo,Carita Augustsson,Bodo Weber,Dirk Frei,Uwe Jenchen +7 more
TL;DR: A provenance model for the Tamatan Group is proposed based on new petrological data, whole-rock geochemical data, and U-Pb LA-ICP-MS detrital zircon age data from these marine fossiliferous strata.
Journal ArticleDOI
Novillo Metamorphic Complex, Huizachal-Peregrina Anticlinorium, Tamaulipas, Mexico: Characterization and development based on whole-rock geochemistry and Nd-isotopic ratios
Eduardo Alejandro Alemán-Gallardo,Juan Alonso Ramírez-Fernández,Bodo Weber,Fernando Velasco-Tapia,Juan Moisés Casas-Peña +4 more
TL;DR: In this article, the Precambrian metamorphic basement exposed in the eroded core of the Huizachal-Peregrina Anticlinorium (Cd. Victoria, Mexico) is described as Novillo Metamorphic Complex (NMC) based on field relations, modal content, whole rock geochemistry and Nd-isotopic ratios.
Journal ArticleDOI
Volcanic sequence in Late Triassic – Jurassic siliciclastic and evaporitic rocks from Galeana, NE Mexico
Esther María Cruz-Gámez,Fernando Velasco-Tapia,Juan Alonso Ramírez-Fernández,Uwe Jenchen,P. Rodríguez-Saavedra,Augusto Antonio Rodríguez-Díaz,Alexander Iriondo +6 more
TL;DR: In this article, the authors provide new petrographic and geochemical data for volcanism included in the El Alamar and Minas Viejas formations outcropping in the Galeana region.
