Resolving space-time strain paths of the Panamint and Cottonwood Mountains, eastern California, through bedrock thermochronology and detrital geochronology
(University of Missouri--Columbia, 2020)
exhumation from [approximately] 8-4 Ma. Zircon He (ZHe) data from the same transect preserve a zircon He partial retention zone (PRZ). In the southern part of the range, AHe ages from Goler Canyon record rapid exhumation at 4 Ma and an AHe PRZ. ZHe data from...
Regional site response and uppermost mantle seismic structure of central and eastern united states
(University of Missouri--Columbia, 2019)
measured. The result shows regions of high velocity such as southern Georgia, eastern South Carolina and NMSZ and low Q[subscript Sn] values. The V[subscript Pn]/V[subscript Sn] ratio shows values higher than the average in regions such as the Mississippi...
Pluton source varition over two magmatic pulses in the white-inyo range, central-eastern California : implications for paleozoic and mesozoic tectonic reconstructions
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This dissertation uses compositions of plutons in the White-Inyo Range (WIR) of central-eastern California, which is an important tectonic boundary as ...
Structural geology and tectonics of the paleoproterozoic rocks of the Mount Rushmore Quadangle, Black Hills, Souh Dakota
(University of Missouri--Columbia, 2006)
and the western edge of the southern projection of the Trans-Hudson orogen (THO). Precambrian rocks of the Black Hills uplift record multiple deformational and metamorphic events related to three orogenic events between 1̃780 and 1690 Ma. Previous workers ascribed...
Seismic tomography and anisotropy : studies of intraplate seismic zones
(University of Missouri--Columbia, 2009)
Both body and surface wave tomography has been applied to some significant intraplate seismic zones to explore the cause of intraplate earthquakes. Pn tomography in the Central and Eastern United States reveals that the ...
Entrainment and transport of coarse stream bed material in a fluviokarst watershed, south-central Missouri : a tracer particle study
(University of Missouri--Columbia, 2010)
The midcontinent of the U.S. is karstified and contains well developed subsurface drainage systems covered by beds of coarse-grained, poorly sorted sediments, resembling those in upland surface streams. Within Tumbling ...
