“…Vicariance of the clade composed of Pecos River species (T. circumstriata and T. cheatumi) presumably reflects separation of this basin from areas to the west and may be attributed to uplift of the southernmost Rocky Mountains (Alvarado Ridge; most pronounced uplift phase 7-4 mya; Eaton, 1987) or associated development of the modern southern Rio Grande Rift in the late Miocene and Pliocene (9-3 mya; Seager et al, 1984;Dickerson and Muehlberger, 1994). The Pecos River Valley developed later in the Pliocene as a result of solution collapse of this region (<3.5 mya; Gustavson and Finley, 1985).…”

“…Although some workers think that integration of the Rio Grande through the Big Bend region occurred relatively recently, around 700 ka (middle Pleistocene; Pazzaglia and Hawley, 2004), others suggest that the Rio Grande was through-flowing by the end of the Pliocene or beginning of the Pleistocene (Gustavson, 1991;Dickerson and Muehlberger, 1994), an interpretation more consistent with the surficial geology of BBNP. The ancestral Rio Grande is thought to have expanded its drainage southward by aggrading basins along its course; as basins filled with sediment, drainages breached divides and spilled into the next lower basin downstream (Henry, 1998;Connell and others, 2005).…”

“…The fault with the greatest amount of offset juxtaposes Eocene and Oligocene sedimentary units of the Chisos Formation in the footwall against Miocene alluvium in the hanging wall, with about 500 m of throw. Dickerson and Muehlberger (1994) …”

“…At the mouth of Santa Elena Canyon ( fig. 1), the fault has about 850 to 900 m of displacement (Maxwell and others, 1967;DeCamp, 1981;Dickerson and Muehlberger, 1994;Lehman and Busbey, 2007), and juxtaposes the Aguja Formation in the hanging wall against Glen Rose Limestone in the foot wall. The fault zone extends 30 km southward into Mexico where throw increases to more than 1,300 m, and it defines the northeast edge of Sierra Ponce, the southeastern extension of Mesa de Anguila (DeCamp, 1981).…”

“…Several authors postulate that the Rio Grande rift extends into northeastern Chihuahua in various forms (e.g., Seager and Morgan, 1979;Dickerson and Muehlberger, 1994;Dickerson, 1995). Gries (1979) suggested that high-angle fault displacements of sub-evaporite rocks do not carry through extensively to the surface because of large-scale flowage of evaporites causing the masking of possible Rio Grande rift basement crustal structures.…”

The Chihuahua trough is a right-lateral pull-apart basin that began to form ~159 to ~156 Ma (Oxfordian) during a period of relative counterclockwise rotation of the North American plate. Jurassic seas were well established by latest Oxfordian time and there was little change in basin configuration throughout the remainder of Late Jurassic, Neocomian and Aptian time. Elements of a broad zone of intersecting pre-existing northwest-trending and north-trending lineaments, along the southwest border of the North American craton, provide the fabric for development of the pullapart basin between the Diablo and Aldama platforms. During Tithonian and Neocomian time sedimentation eventually outpaced tectonic subsidence and, as an ensuing "regressive" event commenced, the eastern area of the Chihuahua trough was the locus of extensive evaporite (including halite) deposition. Near the end of Aptian time, during deposition of the Cuchillo and equivalent formations, faulting along the margins of the Chihuahua trough ceased and the seas began to transgress onto adjacent platform areas. By middle Albian time seas had advanced onto previously emergent areas and the Chihuahua trough became a site of shallow-water carbonate deposition that prevailed, with minor interruptions, until early Cenomanian time. The Ojinaga Formation (early Cenomanian -Santonian?) records a marine clastic influx into the Chihuahua trough, coeval with Upper Cretaceous clastic wedges in the Western Interior Cretaceous Seaway of the United States. Retreat of the Cretaceous sea is reflected in the transition from marine to non-marine beds in the Santonian San Carlos Formation and overlying non-marine El Picacho Formation.During the Laramide orogeny (84 to 43 Ma) the Chihuahua trough was inverted to form the Chihuahua tectonic belt. Laramide deformation is the result of left-lateral transpressional tectonics involving renewed movement along the pre-existing fabric that controlled the location of the Jurassic-Aptian basin. In the evaporite basin portion of the trough (eastern area) reactivation of basin-boundary-faults as Laramide reverse faults, with possible left-lateral components of motion, accompanied by development of gentle "ancestral" folds, was followed by amplification of folds in postevaporite rocks caused by flow of evaporites toward the crests of anticlines. As deformation progressed, structural development involved thrust faulting (principally toward the Diablo Platform) and diapiric injection of evaporites along the margins of the evaporite basin. In the northwestern area of the trough, structure reflects northeast-southwestoriented compression and includes relatively minor southwest-directed thrusting toward and onto the Jurassic Aldama platform. Paleozoic formations are involved in the thrusts and all thrusting can be interpreted as a consequence of faulted basement rather than regional-scale décollement.Post-Laramide tectonic activity includes a continuation of evaporite tectonism, scattered igneous intrusion, minor volcanism, gravity ...
