Austin State University II Structural Analysis of Ernst Tinaja Canyon focusing on Strike-Slip Faulting and Folding, Big Bend National Park , Texas By Ryan Robert Silberstorf, Bachelor of Science Approved: Dr. Chris Barker, Thesis Director Dr. R. LaRell Nielson, Committee Member Dr. Kevin Stafford, Committee Member Dr. Joseph Satterfield, Committee Member Dr. Joseph Musser, Committee Member Richard Berry, D.M.A Dean of the Graduate School III Abstract 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 Orogeny and the Cretaceous-early Tertiary Laramide Orogeny, Tertiary volcanism, and Basin and Range extension. The study area is in Big Bend National Park on the western slopes of the Sierra Del Carmen range at Ernst Tinaja, an erosional pothole in the Cretaceous Buda Limestone. The pothole is in a narrow slot canyon that also features intense folds in thin, flaggy strata of the overlying Boquillas Formation. The complex geology of the Sierra Del Carmen region has been regionally mapped but is lacking in published detailed geologic maps, making this an interesting location for geologic reinvestigation focused on the structural geology of the area. This study presents field data for numerous structures in the study area including folds, normal and thrust faults and a previously unmapped, large dextral strike-slip fault, with associated negative flower structure. Theories for the mechanisms and kinematics of deformation are discussed and a model is presented for the overall tectonic history of the area based on field evidence. Orientations of faults, folds, slickenlines, chatter marks, and fault-juxtapositions of formations were measured. Normal fault mean trends were found to be N16°W, 63°SW and NE, thrust faults mean trends were found to have a mean trend of N19°W, 45°SW. Strike-slip faults mean trends in the study area are N9°W, 70°SW and NE. i Fold axial planes in the study area have a mean strike and dip of N13°W, 71°NE and SW, and bedding in the study area is consistent and trends N25°W, 24°SW. Prominent horizontal slickenlines support the interpretation of strike-slip fault in the N-S trending portion of Ernst Canyon. Three interpretations of the structural evolution of the study area were developed. The first interpretation is that right-lateral movement indicators in the N-S trending canyon were created by dextral strike-slip movement associated with the Basin and Range. This movement reactivated Laramide sinistral strike-slip fault. The second interpretation states the N-S canyon is part of a relay ramp, connecting two en-echelon Basin and Range normal faults. The third interpretation is a combination of the first and second interpretations, and theories that a sinistral strike-slip fault was created during the Laramide Orogeny, Basin and Range normal faults and relay ramps developed next and a late pulse of strike-slip movement during the Basin and Range reactivated the Laramide sinistral strike-slip fault, but with a dextral shear sense. ii Acknowledgements Dr. Chris A. Barker supervised and reviewed this thesis project (2017) at Stephen F. Austin State University and helped with field support for this work and provided many useful discussions concerning this study. Robert Schoen, Cole Hendrickson, Jensen Angelloz are also greatly appreciated for their help and field assistance during the field work portion of this study.

We departed from El Paso on an unusually cool but sunny day – ideal for travelling. El Paso and its suburbs swiftly gave way to the vast expanses of the Chihuahuan Desert. An hour east, and well into the desert, we exited off the freeway at McNary Reservoir. At the exit underpass, we found a small colony of Cave Swallows searching for nest sites. This was a life bird for many in our group. Nearby, we pulled into the completely unassuming McNary Reservoir. From below it appears to be a scrubby, degraded bank. Upon cresting the bank, however, there is a sizeable reservoir. Here we found Clark’s Grebes performing a small portion of their spectacular mating dance that resembles a synchronized water ballet. Western Grebes were also nearby, as were a variety of wintering waterfowl and an unexpected flock of Willet. Gambel’s Quail perched conspicuously and called loudly from the shore. Just as we were about to depart, Lynn spotted a lone Ruddy Duck bringing our total to 17 species of Gambel's Quail birds at our first stop. We stopped for lunch at a colorful Mexican restaurant in Van Horn that has hosted a number of celebrities over the years.

  • Grants in Action by STEVE WAGNER
    NO AMOUNT OF MONEY Grants in Action BY STEVE WAGNER VOLUNTEERS FIND PERSONAL REWARDS IN A WORK PROJECT INSPIRED BY DESERT BIGHORN SHEEP, BUT WHICH BENEFITS ALL KINDS OF WILDLIFE. REPRINTED FROM GAME TRAILS SUMMER 2015 NO AMOUNT OF MONEY irty, smelly and exhausted, Charlie Barnes has never been more gratified. D The DSC Life Member from Trophy Club, Texas, lays down his tools, pulls off his work gloves, draws a deep breath of desert air and bellies up to a tailgate, where a troop of equally sweaty-but-satisfied volunteers is gathering around a cooler of liquid refreshment. Sipping through dry, grinning lips, they gaze upon their collective handiwork. Together, they’ve just finished a project that changes the landscape, both literally and figuratively, for wildlife in the arid Trans-Pecos region of west Texas. Soon, many kinds of species will be sipping here, too. A new guzzler – a device to catch, store and dispense rainwater for thirsty critters – now stands ready for the next downpour. Ready to help the habitat overcome its harshest limitation. “This place has everything it needs to be great habitat for wildlife, except for water, and we just solved that problem,” says Barnes. “Building a guzzler is doing something good for the future, and there’s no amount of money that could replace what I get out of being a part of it.” He explains, “I’m a member of 11 different conservation groups and I volunteer This Reservoir stores rainwater for the dry season. for a multitude of tasks. I help raise money, organize banquets and serve on committees and boards.

  • 1 PATTERNS of MONTOYA GROUP DEPOSITION, DIAGENESIS, and RESERVOIR DEVELOPMENT in the PERMIAN BASIN Rebecca H. Jones ABSTRACT
    PATTERNS OF MONTOYA GROUP DEPOSITION, DIAGENESIS, AND RESERVOIR DEVELOPMENT IN THE PERMIAN BASIN Rebecca H. Jones ABSTRACT Rocks composing both the Montoya (Upper Ordovician) and Fusselman (Lower Silurian) Formations were deposited during the global climate transition from greenhouse conditions to unusually short-lived icehouse conditions on a broad, shallow-water platform. The Montoya and the Fusselman also share many reservoir characteristics and have historically been grouped together in terms of production and plays. Recently, however, the Montoya has garnered attention on its own, with new gas production in the Permian Basin and increased interest in global Ordovician climate. Recent outcrop work has yielded new lithologic and biostratigraphic constraints and an interpretation of four third-order Montoya sequences within Sloss’s second-order Tippecanoe I sequence. The Montoya Group comprises the Upham, Aleman, and Cutter Formations, from oldest to youngest. The Upham contains a basal, irregularly present sandstone member called the Cable Canyon. The boundary between the Montoya and the Fusselman is readily definable where a thin shale called the Sylvan is present but can be difficult to discern where the Sylvan is absent. Montoya rocks were deposited from the latest Chatfieldian to the end of the Richmondian stage of the late Mohawkian and Cincinnatian series (North American) of the Upper Ordovician. Montoya reservoir quality is generally better in the northern part of the Permian Basin where it is primarily dolomite compared to limestone Montoya reservoirs in the south. Reservoir quality is also better in the lower part of the unit compared to the upper, owing to a predominance of porous and permeable subtidal ooid grainstones and skeletal packstones in the former and peritidal facies in the latter.
