Abstract

Paleozoic clastic systems are distributed in northern as well as in southeastern Mexico. In particular, in the Huizachal-Peregrina Anticlinorium in Cd. Victoria, Tamaulipas, occurs a Paleozoic sedimentary sequence, Silurian to Permian in age, which overlies discordantly the Precambrian Novillo Metamorphic Complex of the basement of the Sierra Madre Oriental fold and thrust belt. This sequence has been recently named as Tamatán basin and consists of: (a) fluvio-marginal marine rocks (Cañón Caballeros Fm., Silurian and Vicente Guerrero Fm., Mississippian) (b) clastic-carbonated slope marine sediments (Del Monte Fm., Pennsylvanian) and (c) deep-water sediments (Guacamaya Fm., Permian).

New stratigraphic, petrological, geochemical, and U-Pb zircon geochronological data, allow the characterization of the evolution of the basin, linked to the migration of Gondwana towards Laurentia. According to the new acquired information is possible to determine changes of the provenance and the tectonic setting of the sediments during the Middle-Upper Paleozoic.
