| contents | The Late Triassic-Early Jurassic active continental margin of western North America in northeastern Mexico Margarito Tristán González J. Ramón Torres Hernández Ciencias de la Tierra Triassic Jurassic stratigraphy active margin Exposures of Triassic-Jurassic volcanic sequences in northeastern Mexico suggest that they developed along an activecontinental margin. Other sequences in support of such a tectonic environment are exposed in Durango, Zacatecas, San LuisPotosí, Nuevo León and Tamaulipas, where siliciclastic flysch sediments to the west and an older metamorphic continental blockto the east underlie the volcanics. It is proposed that these Triassic to Jurassic volcanic rocks and associated redbeds from middleto northeastern Mexico are genetically related to a Jurassic active continental margin. The red beds of easternmost Mexico areeither associated with rifting related to the break-up of Pangea, or preferably to a back-arc basin and to the younger transgressiveCallovian to Oxfordian sequence, beginning with redbeds and associated to the basin evolution of the Gulf of Mexico and aneastern passive continental margin. 1998 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56837403 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.4 Vol.37 |
