“…The un deformed Olinalá Formation of Middle to Upper Permian age (Buitrón et al, 2005) is potentially also partially correlative with the Chichihualtepec Tecomate Formation strata, although volcanic rocks have not been described in this unit. Further north, the magmatic arc is characterized by (1) the Early to Middle Permian Tuzancoa Formation (Sierra Madre terrane), which contains andesitic to basaltic lava fl ows and felsic tuffs (Rosales-Lagarde et al, 2005), (2) the Early Permian bentonite-bearing Guacamaya Formation in the Sierra Madre terrane (Gursky and Michalzik , 1989), (3) (McKee et al, 1999), which contains interstratifi ed rhyolites, and (4) the Early Permian, bentonite-bearing Rara Formation of the Sierra del Cuervo in the southern extension of the North American craton (Handschy and Dyer, 1987).…”

“…According to Galas (1977), the pitehblende resulted from a local reaction between uraniferous solutions and pyrite, and the oxidized Stratigraphy of the Sierra Pe•a Blanca in the mining district A small outcrop of metamorphic and folded fiysch (upper Paleozoic Rora Formation) has been observed in the southern part of the sierra (Tovar and Valencia, 1974;Calas, 1977;Handschy and Dyer, 1987). The basement consists mainly of Cretaceous limestones (Stege et al, 1981;Pintigore et al, 1983) slightly folded in the mining district.…”

The Sierra Pefia Bianca district is a good example of uranium deposits related to volcanic rocks, which are here considered to be both the source of the uranium and the host rocks for its deposition. The mineralization occurs mainly in the lower units of a Cenozoic volcanic pile, the Nopal and Escuadra rhyolites, that overlie a Mesozoic calcareous basement.Three genetic types of mineralization have been identified:1. A hydrothermal type, illustrated by the Nopal 1 deposit. The primary mineralization (relics of a pitchblende-pyrite association are observed) and the associated kaolinization of the rock are related to the circulation of hydrothermal fluids in breccias and fault systems. The present-day mineralization consists of mainly U +6 minerals (uranophane, weeksite, etc.) produced during later stages under oxidized conditions. 2. A mixed supergene-exhalative type, exemplified by the Las Margaritas deposit. The UMo minerals precipitated due to the mixing of oxidized, U-enriched ground waters with reduced, H2S-rich fluids in a tectonic valley. A supergene type reflected by the Puerto 3 deposit. The U +6 mineralization (uranophane)is located between two impermeable layers and has a roll shape. The precipitation of this U +6 silicate, with kaolinitc and quartz, is due to an SiO2 enrichment of the solutions at low temperature.

“…In the Sierra del Cuervo in central Chihuahua, late Paleozoic flysch was overridden in mid-Permian to Jurassic time by crystalline rocks of Grenville age along eastverging thrust faults ( Fig. 14) (Handschy and Dyer, 1987;Handschy and others, 1987). A significant unconformity is inferred above the Precambrian and Paleozoic rocks because Triassic to Middle Jurassic strata are absent (Fig.…”

“…In Chihuahua, known Precambrian basement includes granite gneiss encountered at depths of 4 to 5 km in two PEMEX wells; two small outcrops of fault-bounded metaplutonic rocks intruded by amphibolite dikes and pegmatites within Permian flysch in the Sierra del Cuervo, about 15 km north-northwest of Aldama; and small fault-bounded outcrops of undated amphibolite gneiss near Rancho El Carrizalillo, about 80 km east of Sierra del Cuervo (Thompson and others, 1978;Mauger and others, 1983;Quintero-Legorreta and Guerrero, 1985;Handschy and Dyer, 1987;Blount and others, 1988). Radiometric dates (Table 10) are similar to those of Grenville rocks in western and central Texas (Copeland and Bowring, 1988;Walker, 1992).…”

“…During latest Pennsylva-nia^?) and Early Permian time, the southern part of the Pedregosa basin in central Chihuahua subsided rapidly, as indicated by the deposition of thick basinal flysch and pelagic rocks; minor tuff and conglomerate composed exclusively of rhyolite clasts may indicate proximity to a cryptic Early Permian volcanic arc (de Cserna and others, 1968;Mellor and Breyer, 1981; Torres-Roldán and Wilson, 1986;Handschy and Dyer, 1987;Handschy and others, 1987). In the Sierra del Cuervo in central Chihuahua, late Paleozoic flysch was overridden in mid-Permian to Jurassic time by crystalline rocks of Grenville age along eastverging thrust faults ( Fig.…”

Part 1 of this work (Sedlock, Ortega-Gutiérrez, and Speed) is a synthesis of geoscientific data pertaining to México and northern Central America using the framework of a new division of these regions into tectonostratigraphic terranes. First, we review the morphotectonic provinces and the modern plate tectonic framework of the region. Next, we present data for 17 terranes that, except for North America, are named after indigenous cultures. Terrane descriptions are based on published and unpublished geophysical and geologic data of all types, utilizing a much more extensive data base than that used in previous terrane divisions. Each terrane description includes, if possible, an interpretive geologic and tectonic history focusing on distinctive features; a description of constituent rock units, with extended descriptions of especially significant or controversial units; a schematic tectonostratigraphic column, which in many cases shows geographic variation in the form of a structure section; and a compilation of radiometric data, including dates, system used, errors, and sources. Finally, we discuss the rationale for distinguishing individual terranes and summarize data concerning the orientation, nature, and kinematic history of terrane boundaries. An extended reference list is included.Part 2 of this work (Sedlock, Speed, and Ortega-Gutiérrez) is a speculative model of the Late Precambrian to Cenozoic tectonic evolution of the terranes that comprise México and northern Central America. First, we discuss numerous formal premises on which the model is predicated, including Late Jurassic sinistral slip on the Mojave-Sonora Megashear and Late Cretaceous-Paleogene northward displacement of Baja California. Next, we review constraints imposed by plate motion models on the tectonic evolution of the region. Finally, we present a reconstruction of the tectonic evolution of the region that, while certainly not a unique solution, is an internally consistent solution that is testable in many respects.The following are a few of the salient features of the reconstruction. (1) Grenville basement in eastern and southern México is regarded to be far-traveled with respect to the southern termination of the Grenville belt in North America. (2) The late Paleozoic Ouachitan suture that marks the collision of North America and Gondwana does not and did not extend into central México. (3) The Permo-Triassic continental arc on the western margin of Pangea affected only the far eastern edge and far northwestern corner of México; most of what is now México was a complex assemblage of arcs, continental blocks, and basins in the oceanic region west and south of the Pangean continental arc. (4) Continental México grew most markedly toward its present form during the Late Triassic and Jurassic as terranes were episodically accreted to its southern and western flanks. (5) Mesozoic southward and westward continental growth was accompanied by a southward and westward shift of the locus of arc magmatism. (6) The technically active southern and ...
