“…14A and 14B). Therefore, our data support previous reconstructions that suggest that the development of the Tamaulipas-Chiapas transform fundamentally influenced the tectono-sedimentary evolution of Mexico during Early and Middle Jurassic time (Goldhammer, 1999;Padilla and Sánchez, 2007;Pindell and Kennan, 2009;Nova et al, 2019 Research Paper hand, recognizing the Salado River-Axutla fault as a major Lower-Middle Jurassic structure controlling the evolution of adjacent sedimentary basins shows that continental extension during Pangea breakup was also accommodated by WNW-trending faults. Therefore, our work offers a new perspective for researchers that aim to reconstruct the kinematics of Pangea breakup in Mexico.…”

During Pangea breakup, several Jurassic extensional to transtensional basins were developed all around the world. The boundaries of these basins are major structures that accommodated continental extension during Jurassic time. Therefore, reconstructing the geometry of Jurassic basins is a key factor in identifying the major faults that produced continental attenuation during Pangea breakup. We reconstruct the tectono-sedimentary evolution of the Jurassic Tlaxiaco Basin in southern Mexico using sedimentologic, petrographic, and U-Pb geochronologic data. We show that the northern boundary of the Tlaxiaco Basin was an area of high relief composed of the Paleozoic Acatlán Complex, which was drained to the south by a set of alluvial fans. The WNW-trending Salado River–Axutla fault is exposed directly to the north of the northernmost fan exposures, and it is interpreted as the Jurassic structure that controlled the tectono-sedimentary evolution of the Tlaxiaco Basin at its northern boundary. The eastern boundary is represented by a topographic high composed of the Proterozoic Oaxacan Complex, which was exhumed along the NNW-trending Caltepec fault and was drained to the west by a major meandering river called the Tlaxiaco River. Data presented in this work suggest that continental extension during Pangea breakup was accommodated in Mexico not only by NNW-trending faults associated with the development of the Tamaulipas–Chiapas transform and the opening of the Gulf of Mexico, but also by WNW-trending structures. Our work offers a new perspective for future studies that aim to reconstruct the breakup evolution of western equatorial Pangea.

“…The subsequent subduction of the Caribbean plate beneath the South American continental margin is responsible for the formation of a short-lived Paleocene-Eocene magmatic arc (Cardona et al, 2011b(Cardona et al, , 2014Bayona et al, 2012;Bustamante et al, 2017). The oblique nature of the Caribbean-South American plates interactions has been inferred mainly from palaeogeographic reconstructions, including palaeomagnetic evidences of block rotation, lithotectonic correlation and basin filling histories (Escalona and Mann, 2003;Pindell and Keenan, 2009;Montes et al, 2010Montes et al, , 2019Boschman et al, 2014;Nova et al, 2019).…”

Anisotropy of magnetic susceptibility (AMS) and anhysteretic remanence (AAR) were used to evaluate the emplacement history of the Parashi stock and related dyke swarm situated in NW Colombia. The average magnetic susceptibility of 4.5×10-2 SI, in conjunction with low-coercivity components provided by the isothermal remanence and thermomagnetic curves with net Verwey and Curie transitions, indicates that multidomain magnetite records the anisotropy directions. The similar orientation and shape of the AMS and AAR ellipsoids indicate the absence of very fine magnetite with an inverse fabric. The magnetic foliation is the best-defined fabric element in these rocks and outlines a concentric structure, elongated parallel to the NE-SW direction of the pluton. Crystallisation age of the stock and dykes (51-47 Ma), along with pressure of emplacement determination indicate that the stock and the dyke swarm probably formed simultaneously, and they were emplaced in the shallow crust (

El uso de métodos geoquímicos de discriminación tectónica indican que las rocas volcánicas desde la Formación Saldaña, en el valle Superior del Magdalena hasta la Península de la Guajira se formaron en una zona de subducción ubicada en el margen activo de Gondwana (Pinilla-Ocampo, 2013;Salazar-Torres et al, 2013;Nova et al, 2019).…”

“…Durante el intervalo Triásico-Jurásico, el sector al este de la actual Cordillera Central registró una de las fases magmáticas más importantes de Colombia, caracterizada por grandes intrusiones y depósitos volcánicos coetáneos con sedimentación marina y continental (e.g. Ayala-Calvo et al, 2005;Bayona et al, 1994;Correa-Martínez et al, 2020;Geyer, 1969Geyer, , 1973Mojica et al, 1985;Mojica y Llinás, 1984;Nova et al, 2019;Rodríguez-García y Obando, 2020;Tschanz et al, 1974). Según Leal-Mejía et al (2018) el pico máximo de esta fase magmática se alcanzó a finales del Jurásico Temprano y el registro magmático abarca cuerpos plutónicos de naturaleza intermedia a ácida y productos efusivos que van desde basaltosandesitas hasta riolitas.…”

Petrografía y geoquímica de las rocas piroclásticas y efusivas de la Formación Bocas (Triásico Superior-Jurásico Inferior) y efusivas de la Formación Nogontova (Macizo de Santander, Colombia)

La secuencia de rocas volcánicas y volcano-sedimentarias reportadas en el segmento superior de la Formación Bocas, subyacen sedimentos rojos de la Formación Jordán, está constituida por derrames de lavas máficas a intermedias y rocas piroclásticas félsicas interestratificadas con lodolitas, areniscas y areniscas tobáceas. En este trabajo se exponen nuevos datos de campo, petrográficos y geoquímicos de una secuencia volcánica máfica y volcanoclástica félsica. En cercanías al corregimiento Las Bocas, las rocas básicas presentan bajos contenidos TiO2 (1,04 - 1,65% peso) y P2O5 (0,3 - 0,7% peso) y altos contenidos de Al2O3 (15,79 - 15,92% peso), dentro de las series toleíticas; estas rocas se caracterizan por tener un leve enriquecimiento de LREE, anomalías positivas en Th, U y Zr y anomalías negativas en Nb, Ta y Ti con tendencias de ambiente MORB. Las rocas félsicas que corresponden a rocas piroclásticas de composición riolítica están enriquecidas en álcalis y LREE con anomalías negativas Ba, Sr, Nb, Ta y Ti y enriquecimiento moderado en LREE con un patrón característicos de intraplaca. Por otra parte, la geoquímica de los basaltos de la Formación Nogontova indica un ambiente de tipo MORB. Estos datos y los obtenidos para las rocas de la Formación Bocas sugieren un ambiente de extensión intracontinental (back arc) asociado a subducción.
