A Vascular Flora Of The Southern Inyo Mountains, Inyo County, California, Maria J. Jesus
A Vascular Flora Of The Southern Inyo Mountains, Inyo County, California, Maria J. Jesus
Aliso: A Journal of Systematic and Floristic Botany
The Inyo Mountains in Inyo County, California, are an arid mountain range located between the eastern Sierra Nevada and Death Valley National Park. The study site is ca. 433 km2 (167 sq mi), ranging in elevation from 549 to 2955 m (1800 to 9694 ft), and comprises the southern extent of the Inyo Mountains where the Great Basin Desert and Mojave Desert bioregions meet. This area had been poorly represented by botanical collections despite an abundance of distinctive biogeographic features and high diversity in rare and endemic plant species. The objectives of this study were to complete a specimen-based, …
Structural Deformation Across The Southwest Mina Deflection, California-Nevada: Field Studies In The Huntoon Spring Quadrangle, Eliya R. Hogan
Structural Deformation Across The Southwest Mina Deflection, California-Nevada: Field Studies In The Huntoon Spring Quadrangle, Eliya R. Hogan
All Master's Theses
New geologic data provides insight into Pliocene strain rates across the southwest Mina deflection. 40 Ar/39 Ar geochronology of geologic units indicate cooling of Miocene ignimbrite at 11.86 ± 0.01 Ma, Pliocene basalt lavas at 3.7241 ± 0.0051 and 3.5262 ± 0.0172 Ma, and basaltic andesite and andesite lavas at 3.4715 ± 0.0107 Ma and 3.1078 ± 0.0088 Ma. Pliocene cinder cones and Quaternary sediments are also exposed in the Huntoon Spring quadrangle. Volcanic units are cut by a dominant set of NNE-, NE-, and ENE- striking sinistral faults and a lesser set of NNW- and NW- striking normal …
Controls On Fault Geometry During Early Stages Of Extension In The Larkspur Hills, Northwest Basin And Range, Diana Jean Strickley
Controls On Fault Geometry During Early Stages Of Extension In The Larkspur Hills, Northwest Basin And Range, Diana Jean Strickley
All Master's Theses
Detailed analyses of normal faults in the Larkspur Hills, CA-NV, northwest Basin and Range, offer insight into factors controlling normal fault initiation, growth, and distribution. N-trending faults in the southern portion of the study area share trends of major range-bounding structures and Pliocene linear volcanic vents; in contrast, NNW- and NNE- trending faults dominate further north and into south-central Oregon. Stress analyses and comparison with experimental and field data suggest that preexisting structures control faults in the northern Larkspur Hills, while faults form perpendicular to σ3 in the southern hills. The change in fault orientations is abrupt, occurring across a …
Paleoseismologic Evidence For Holocene Activity On The Pinto Mountain Fault, Twentynine Palms, California, Ana Maria Cadena
Paleoseismologic Evidence For Holocene Activity On The Pinto Mountain Fault, Twentynine Palms, California, Ana Maria Cadena
All Master's Theses
Excavations across the Pinto Mountain fault in Twentynine Palms, California exposed faulted strata across a 32-m wide zone. Trench wall exposures revealed clear evidence for five ground-rupturing events during the Holocene, and two additional events in the late Pleistocene. Optically stimulated luminescence ages from alluvial sediments suggest that the most recent event occurred between 1.7-2.9 ka B.P. and the penultimate event between 2.7-4.2 ka B.P.. Prior to the penultimate event, there were five ground-rupturing earthquakes on the eastern Pinto Mountain fault between 3.5-13.6 ka B.P.. The average recurrence interval since 13.3-13.6 ka B.P. is 1510-1680 years, and 1200-1500 years in …
Holocene Earthquakes And Late Pleistocene Slip Rate Estimates On The Wassuk Range Fault Zone, Nevada, Usa, J. M. Bormann, Benjamin E. Surpless, M. W. Caffee, S. G. Wesnousky
Holocene Earthquakes And Late Pleistocene Slip Rate Estimates On The Wassuk Range Fault Zone, Nevada, Usa, J. M. Bormann, Benjamin E. Surpless, M. W. Caffee, S. G. Wesnousky
Earth and Environmental Geosciences Faculty Research
The Wassuk Range fault zone is an 80‐km‐long, east‐dipping, high‐angle normal fault that flanks the eastern margin of the Wassuk Range in central Nevada. Observations from two alluvial fan systems truncated by the fault yield information on the vertical slip rate and Holocene earthquake history along the range front. At the apex of the Rose Creek alluvial fan, radiocarbon dating of offset stratigraphy exposed in two fault trenches shows that multiple earthquakes resulted in 7.0 m of vertical offset along the fault since ∼9400 cal B.P. These data yield a Holocene vertical slip rate of 0.7±0.1 mm/yr. The south trench …

Gis Analysis Of The Pre And Post-Diversion Water Balances In Owens Valley, California, Anna Corinne Draa
Gis Analysis Of The Pre And Post-Diversion Water Balances In Owens Valley, California, Anna Corinne Draa
UNLV Retrospective Theses & Dissertations
Owens Valley, California is located at the western border of both the Basin and Range and Great Basin Provinces. The valley is hydrologically closed; the only outflow for ground and surface waters is evaporation to the atmosphere. Los Angeles Department of Water and Power (LADWP) began diverting water from Owens Valley in 1913 and has steadily increased the amount of water removed from the valley since then; LADWP has always assumed that the hydrologic system as it existed in 1913 was in equilibrium with modern climate. This study develops a geographical information systems (GIS) based model of Owens Valley to …
Refined Kinematics Of The Eastern California Shear Zone From Gps Observations, 1993-1998, M. Meghan Miller, Timothy H. Dixon, Roy K. Dokka
Refined Kinematics Of The Eastern California Shear Zone From Gps Observations, 1993-1998, M. Meghan Miller, Timothy H. Dixon, Roy K. Dokka
All Faculty Scholarship for the College of the Sciences
Global Positioning System (GPS) results from networks spanning the Eastern California shear zone and adjacent Sierra Nevada block, occupied annually between 1993 and 1998, constrain plate margin kinematics. We use an elastic block model to relate GPS station velocities to long‐term fault slip rate estimates. The model accounts for elastic strain accumulation on the San Andreas fault, as well as faults of the Eastern California shear zone. South of the Garlock fault, 14 mm/yr of dextral shear is distributed across the Eastern California shear zone. Some of this slip penetrates eastward into the Basin and Range, and a collective budget …
