  • Abstracts of REU Student Reports (SAGE 2012)
    Abstracts of REU Student Reports (SAGE 2012): Evaluating Galvanic Distortion: A Comparison of Phase Tensors and Polar Diagrams Diana Brown Abstract: Galvanic distortions result from conductivity gradients. This is a fundamental concept in magnetotellurics (MT). However, distortions from shallow, small-scale heterogeneities can lead to statically shifted data. MT sites taken from a geophysical study of the Caja del Rio region of New Mexico, were analyzed for the presence of galvanic distortion. Utilizing phase tensors and polar diagrams, a comparative study was completed. Comparing the dimensionality represented by polar diagrams to that of phase tensors provides a qualitative indicator of distortion. Sites with opposing dimensionalities were those with statically shifted data. Conversely, sites with diagrams in agreement were distortion free. 1D inversion models were run from both pre and post static shift corrected sounding curves. This direct comparison of inversions illustrates how distortions can be manifested in a geologic model. Seismic Reflection: Velocity Analysis using Constant Velocity Stacks Emily Butler Abstract: The Caja del Rio area is characterized with volcanics near the surface. The goal of the seismic reflection line is to be able to determine the depth and thickness of the volcanics as well as any other significant formations. Specifically, applying an appropriate velocity analysis is key in determining the correct reflectors and reflector depth. The goal of velocity analysis using constant velocity stacks is to flatten out as many reflectors as possible by applying the correct velocity function in order to produce a stack that can be interpreted. Velocity analysis using constant velocity stacking involves developing many stacks, all with different constant velocities and determining where each reflector flattens out and at which velocity.

This is one of many related papers that were included in the 2007 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

    Sedimentology, provenance, and tectonic setting of the Miocene Horse Camp Formation (Member 2), east-central Nevada by Brian Keith Horton A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Earth Sciences Montana State University © Copyright by Brian Keith Horton (1994) Abstract: A study of the sedimentology, compositional trends, and modem tectonic setting of a 1600 m-thick sedimentary succession provides information on the late Cenozoic paleogeography and tectonics of an extensional basin and adjacent orogen in the Basin and Range province of east-central Nevada. Interpretations of depositional environments and reconstructions of paleogeography utilize detailed sedimentologic analyses of fourteen distinct facies and four facies associations from nine measured stratigraphic sections. Conglomerate compositional data and considerations of modern tectonic setting and local geologic structures provide constraints on the tectonic development of the extensional basin and orogen. Within the Miocene Horse Camp Formation (Member 2), four facies associations are defined by specific combinations of fourteen potential facies and attributed to processes characteristic of particular depositional environments. Subaerial and subaqueous fan-delta environments were characterized by deposition of sediment gravity flows and an absence of fluvial processes. A nearshore lacustrine facies association recorded wave-influenced sedimentation near a lake shoreline. Quiet-water deposition and limited sediment gravity flows characterized an offshore lacustrine environment. Lateral facies variations and stratal thinning and fining trends suggest a sediment source terrane to the south/southeast in the northern Grant Range. Simulated unroofing of this source terrane generated a hypothetical clast composition suite that is similar to actual conglomerate compositional data from Member 2.

Graham, Pennsylvania State University Research Interests My research interests focus on the anatomy, phylogeny, life history, along with biomechanics and behavior of extinct and extant animals. Understanding the anatomy, morphology, and phylogenetic relationships allow for a more thorough understanding of the animals themselves. Additionally, this allows for more information to be gathered on the life history and behavior of these animals. Understanding these things in extant animals allows one to infer and gain a better understanding in extinct and fossil animals, but also leads to a better understanding how animals live today and in the past. I analyze the biomechanics and behavior, or potential behavior, of extant and extinct animals. I seek to bring life to fossils, and not only does this include describing and analyzing individual extinct animals and fossils but investigating faunas and ancient ecosystems as well.
