Geology of the Northern Alto Relex Area, Big Bend National Park, Brewster County, Texas
… scarp. Cretaceous rocks in the area were folded and faulted by Laramide compression, intruded by Tertiary sills and overprinted by high-angle normal faults from Basin and Range extension. During the Laramide Orogeny and Basin and Range extension, the underlying basement shear zone called, the …

Structural Analysis of the Northwest Wind Mountain Quadrangle, New Mexico: Proterozoic Shearing to Cenozoic Brittle Faulting in the Burro Mountains
… prompting detailed (1:12,000) geologic mapping and collection of structural data. The study area has a complex tectonic history, including 1) ~1.65 Ga metamorphism during accretion of the Mazatzal terrane to Laurentia’s southern margin; 2) ~1.4 Ga intrusion of Granite and Rhyolite Province …

Pluton source varition over two magmatic pulses in the White-Inyo range, central-eastern California : implications for paleozoic and mesozoic tectonic reconstructions
… uses compositions of plutons in the White-Inyo Range (WIR) of central-eastern California, which is an important tectonic boundary as it is the easternmost extent of the Mesozoic Cordilleran arc and the western edge of Basin and Range extension. The main goal of this dissertation is to understand …

Structural Analysis of Rock Canyon Near Provo, Utah
… (near Provo, Utah) provides insight into Wasatch Range tectonics and fold-thrust belt kinematics. Excellent exposures along the E-W trending canyon allow the use of digital photography in conjunction with traditional field methods for a thorough analysis of Rock Canyon's structural features. …

The kanarra fold-thrust system -- The leading edge of the sevier fold-thrust belt, southwest Utah
… scientific curiosity in tectonics, stratigraphy, and industry. Understanding its development in southwest Utah is hindered in part due to the multiple origins proposed for the Kanarra anticline, a major leading edge structure -- a drag fold along the Hurricane fault, Laramide monocline, Sevier …

Structural Analysis of Ernst Tinaja Canyon Focusing on Strike-Slip Faulting and Folding, Big Bend National Park, Texas
<p>Basement and cover rocks in the Sierra Del Carmen Mountains in eastern Big Bend National Park were affected by multiple tectonic events. The Big Bend/Trans-Pecos area experienced shearing during Precambrian formation of the Texas Lineament, compression during the Paleozoic Ouachita-Marathon …

Investigation of iron isotope variability in the bimodal Aztec Wash Pluton, Eldorado Mountains, Nevada
Over the course of the past decade, our understanding of silicic plutons has undergone a fundamental shift, from envisioning pluton emplacement as one large magmatic intrusion to the concept of incremental emplacement, in which plutons form from multiple smaller injections of magma over hundreds of …
