Title: Time for anisotropy: The significance of mechanical anisotropy for the development of deformation structures

Abstract

The forty-year history of the Journal of Structural Geology has recorded an enormous increase in the description, interpretation and modelling of deformation structures. Amongst factors that control deformation and the resulting structures, mechanical anisotropy has proven difficult to tackle. Using a Fast Fourier Transform-based numerical solver for viscoplastic deformation of crystalline materials, we illustrate in this paper how mechanical anisotropy has a profound effect on developing structures, such as crenulation cleavages, porphyroclast geometry and the initiation of shear bands and shear zones.

Competing Deformation Mechanisms in Periclase: Implications for Lower Mantle Anisotropy

Journal Article Lin, Feng ; Couper, Samantha ; Jugle, Mike ; ... - Minerals

Seismic anisotropy is observed above the core-mantle boundary in regions of slab subduction and near the margins of Large Low Shear Velocity Provinces (LLSVPs). Ferropericlase is believed to be the second most abundant phase in the lower mantle. As it is rheologically weak, it may be a dominant source for anisotropy in the lowermost mantle. Understanding deformation mechanisms in ferropericlase over a range of pressure and temperature conditions is crucial to interpret seismic anisotropy. The effect of temperature on deformation mechanisms of ferropericlase has been established, but the effects of pressure are still controversial. With the aim to clarify and quantify the effect of pressure on deformation mechanisms, we perform room temperature compression experiments on polycrystalline periclase to 50 GPa. Lattice strains and texture development are modeled using the Elasto-ViscoPlastic Self Consistent method (EVPSC). Based on modeling results, we find that { 110 }more »« less

Late Cretaceous ductile deformation, metamorphism and plutonism in the Piute Mountains, eastern Mojave Desert

Journal Article Fletcher, J M ; Karlstrom, K E - Journal of Geophysical Research; (United States)

Late Cretaceous deformation in the Piute Mountains involved ductile thrusting on a network of anastomosing northeast and southwest directed shear zones. The shear zones often separate Proterozoic lithologies with strong competency contrasts, suggesting that Proterozoic crustal anisotropies were important in controlling the geometry of the shear zone network. Shear zones now divide the crust into wedge- and lozenge-shaped blocks. The Piute Mountains can be separated into two kinematic domains, each characterized by a dominant sense of shear. Thrusting in the southwest directed kinematic domain ended at 85 {plus minus} 7 Ma, the age of the late synkinematic East Piute pluton.more »« less

Meso- and microfabric analysis of eastern Blue Ridge rocks at Glade Gap, North Carolina

Conference Geddes, D J ; Green, M D ; Hatcher, Jr, R D - Geological Society of America, Abstracts with Programs; (United States)

Glade Gap is located in the hanging wall of the Chunky Gal Mountain (Shope Fork ) thrust sheet, a higher tectonic unit in the Hayesville sheet in the eastern Blue Ridge, about 5 km east of Shooting Creek, North Carolina. The rocks here are complexly deformed and were metamorphosed to upper amplibolite facies (sillimanite II) assemblages during the early to middle Paleozoic thermal peak. Evidence for only one high-grade metamorphic event is present here, although minor chlorite (after biotite) and sericite (after feldspar) are present indicating some late retrogression has occurred. Protoliths consisted of mafic igneous rocks (part of themore »« less
High temperature and pressure experimental rock deformation

Conference Tullis, J - Geol. Soc. Am., Abstr. Programs; (United States)

Experimental studies provide information on the mechanisms and rheology of deformation which have great significance for the understanding of the processes and mechanics of small through large-scale structures; introduction of this material at the undergraduate level makes structural geology more exciting and satisfying because it is one way of moving beyond the purely descriptive. Deformation experiments have shown that there are a relatively small number of grain-scale deformation mechanism, each of which tends to be dominant at a given set of conditions, has an associated rheology or flow law, and a characteristic set of microstructures.

On the effect of anisotropy and inertia on shear banding: Instability of biaxial stretching

Journal Article Zhu, H ; Zbib, H M ; Aifantis, E C - Applied Mechanics Reviews

The instability of biaxial stretching leading to the development of shear bands in viscoplastic materials with both isotropic hardening and kinematic hardening is examined. The main issues are to evaluate the effect of anisotropy and inertia on the onset of instability and to examine the development and evolution of an inhomogeneous deformation structure, using both a linear analysis and a nonlinear finite element analysis. It is shown that the back stress and plastic spin, modeling deformation induced anisotropy and texture development, have a significant influence on the critical state at which the first instability occurs.
