    Description: The Grenville Province is a remnant of a ca. 1.1 Ga orogen, exposed as a continuous belt in northeastern North America. Rocks showing evidence of Grenville-aged deformation occur all over the world and represent the final amalgamation of the Proterozoic supercontinent Rodinia. By studying the timing and nature of motion along crustal-scale, ductile shear zones, it is possible to place constraints on the tectonic history of this part of the Grenville orogen. This, in turn, provides information on how the lithosphere evolves after a major orogenic event and what kinds of driving mechanisms play a major role in post-orogenic modification and stabilization of the crust. To constrain the temporal evolution of these shear zones, a detailed structural and thermochronologic study was undertaken across the Metasedimentary Belt in the southeastern portion of the Grenville Province in Ontario and New York State. Ages are based on radiogenic isotope analysis, using the decay of potassium to argon in...

    Editeur: ProQuest Dissertations Publishing
    Date: 2009
    Sujet: Geology ; Geology ; Earth Sciences ; Appalachian Foreland ; Fold-Thrust Belt ; Orogenic Curvature ; Paleomagnetism ; Tennessee Salient
    Description: Formed during the Alleghanian orogeny, the southern Appalachian foreland fold-thrust belt displays curvature at the scale of an individual structure to the entire thrust belt. Using an integrated approach, this study shows that secondary rotations are not required to accommodate curvature, which contrasts with observation in curved belts elsewhere. In the Tennessee salient, the southern Appalachian fold-thrust belt displays a significant degree of curvature (∼55°). Early, layer-parallel paleostress orientations recorded in calcite twins show a systematically fanned distribution that correlates with the overall strike distribution for limestone sites within both the fold-thrust belt and the “undeformed” foreland, indicating primary curvature of the salient. Moreover, the degree of fanning matches the geometry of the hinterland Blue Ridge front instead of the most forward section of the belt, implying that indentation by the Blue Ridge allochthon produced both the curvature of the Tennessee...

    Editeur: ProQuest Dissertations Publishing
    Date: 2001
    Sujet: Geology ; Geology ; Earth Sciences ; Antarctica ; Cenozoic ; Climate Change ; Cretaceous
    Description: The climatic evolution of Antarctica is intimately linked with global climate through the processes of oceanic and atmospheric circulation. Analyses and understanding of different climatic states in the past enable a better understanding of processes that control climate and the likely impact of future climate change. The climatic evolution of Antarctica and its association with the surrounding oceanic circulation are determined using sediment parameters in cores from around Antarctica. These measures include terrigenous flux rates and grain size analysis, bulk magnetic susceptibility values, and magnetic fabrics, measured in samples obtained from Ocean Drilling Program cores that surround Antarctica. Samples extend through the latest Cretaceous and span the time period from before ice formation occurred on Antarctica in the Cretaceous through the onset of modern conditions. Sites analyzed include the Maud Rise in the southern Atlantic Ocean, Kerguelen Plateau in the southern Indian Ocean,...

    Description: Changes in ocean circulation, as reflected in physical property changes of sediments from deep-sea drift deposits, were studied using grain size and magnetic fabric. The goal was to gain an understanding of abyssal circulation since the late Miocene, a time of tectonic and climatic change. Sediment samples from two North Atlantic drifts were analyzed, using a variety of physical and geochemical techniques. Sedimentation at these drifts is directly influenced by North Atlantic Deep Water, a pivotal water mass in the global circulation pattern. The data show a marked slowing of abyssal currents at with drift-related deposition slowing at the deeper site occurring 2 m.y. before that at the shallower site. The change at the shallower site occurred at 2.6 Ma, the time of onset of Northern Hemisphere Glaciation. Stable isotope analysis reveals a warmer, more saline water mass at the deeper site prior to approximately 5 Ma that can be associated with late Miocene Mediterranean water. Samples from...

    Description: The Robertson Lake shear zone (RLSZ) is a low angle ($\sim$30$\sp\circ$ SE dip), plastic to brittle extensional shear zone that separates the Mazinaw (footwall) and Sharbot Lake (hanging wall) domains in the southeastern Grenville Orogen, Ontario, Canada. The shear zone contains crystal plastic and brittle structures that consistently indicate a normal sense of shear. Based on U-Pb ages of sphene the last metamorphism in the Sharbot Lake domain is $\sim$1160 Ma, which is older than that of the Mazinaw domain (1020-1050 Ma). Metamorphic pressures vary in the region, increasing toward the shear zone in the footwall, decreasing across the zone and increasing away from the shear zone in the hanging wall. Well constrained metamorphic ages in the region allow metamorphic pressure to be correlated with depth across the region at the time of metamorphism. The gradients in pressure near the RLSZ imply significant fault rotation ($\sim$50$\sp\circ$) associated with extension. Cooling ages ($\sp{40}$Ar-$\sp{39}$Ar)...

    Date: 1994
    Sujet: Geology ; Geophysics ; Geology ; Geophysics ; Earth Sciences
    Description: Accurate quantification of preferred orientation fabrics in deformed rocks with magnetic anisotropy requires an understanding of the behavior of the mineralogical carrier(s) of magnetic anisotropy. Rock magnetic and petrologic studies were conducted to identify which mineral(s) carry the anisotropy in slates and deformed anorthosites. In the Martinsburg Formation, Lehigh Gap, Pennsylvania, anisotropy of magnetic susceptibility (AMS) is controlled by chlorite. Characteristics of the AMS ellipsoids are consistent with numerical model results of composite magnetic fabrics arising from the addition of two orthogonal, oblate component fabrics. The composite AMS fabrics in the Martinsburg Formation result from progressive dissolution/new-growth of chlorite during cleavage formation. The composite nature of the AMS fabrics shows that the shape of the AMS ellipsoid cannot be used to quantify the mineral fabrics of these slates. The combined results of anhysteretic remanent magnetization anisotropy...

    Sujet: Geology ; Geology ; Earth Sciences
    Description: A study of structural field relations and rock strains, in both the country rock and younger synorogenic veins, along a traverse across the central Idaho-Wyoming fold-and-thrust belt has revealed the following groups of out-of-sequence deformations: (1) 'piggyback' or overprinted deformations, (2) footwall and basement deformation. Each group contradicts the view of overall cratonward-younging and shortening of sedimentary wedge as it transforms into a fold-and-thrust belt. Analysis of mechanically twinned calcite in the country rocks of each of the major thrust sheets (Paris to Prospect sheets) reveals a distinct pre-thrust translation layer-parallel shortening fabric. This fabric shows a consistent clockwise rotation from west to east (Paris to Prospect sheets) which can be interpreted as having formed by a curvilinear strain field followed by west to east thrust sheet translation. This interpretation is supported by a properly restored Jurassic North American margin which was a site...

    Description: Phyllosilicates are the principal components of phyllosilicate-rich diagenetic to low-grade metamorphic rocks such as mudstones, shales, and slates, and are among the most common rock types on the Earth's surface. Understanding how the chemical composition, structure and textures of phyllosilicates in those rocks evolved under different geological conditions provides critical information about many geological processes in the upper crust. Advances in electron microbeam technology have made it possible to study fine-grained phyllosilicates in detail. However, a piece of critical information, the dimensional and crystallographic preferred orientation of phyllosilicates, is not easily obtained. This dissertation was designed to develop a method and systematically examine preferred orientation development of phyllosilicates in environments from diagenetic to low metamorphic grades, using a combination of transmission X-ray texture goniometry and electron microscopy. Samples from various environments...
