Fabric evolution of rigid inclusions during mixed coaxial and simple shear flows

Applications of inclusion behaviour models to a major shear zone system: The Nordfjord-Sogn Detachment Zone in western Norway

“…Schmid and Podladchikov, 2004). Further studies on the effects of adding pure shear to simple shear on rotation rate and fabric development include Passchier (1987), Jezek et al (1996) and Marques and Coelho (2003).…”

“…While the above mentioned fundamental solutions are valid for any kind of far field flow they are somewhat difficult to evaluate (e.g. Freeman, 1987;Jezek et al, 1996). Ghosh and Ramberg (1976) reduced the complexity by studying two-dimensional systems of rigid, isolated elliptical clasts embedded in a viscous matrix that undergoes combined pure and simple shear far-field flow.…”

Asymmetrical to symmetrical magnetic fabric of dikes: Paleo-flow orientations and Paleo-stresses recorded on feeder-bodies from the Motru Dike Swarm (Romania)

“…3a). This is based on several arguments: experimental flowing evidence (Merle, 1998), theoretical evidence (Komar, 1972a(Komar, ,b, 1976, observation of strained vesicles (Coward, 1980;Rust and Manga, 2002), evolution of a magmatic fabric during a simple shear (Ildefonse and Fernandez, 1988;Ildefonse et al, 1992a,b;Arbaret et al, 1996Arbaret et al, , 2000Arbaret et al, , 2001Marques and Coelho, 2003) or a combination of simple and pure shear (Ježek et al, 1996). We consider that the flow pattern induces the coexistence of two strain regimes, evolving from simple shear, near the dike's wall to a mainly pure shear in the core of the dike (Fig.…”

On the dynamics of magma mixing by reintrusion: implications for pluton assembly processes

“…This has motivated the study of¯uid±particle interactions in simple systems to elucidate the dynamical history of magma bodies. A number of experimental and numerical studies of multiphase¯ow at low Reynolds number (creeping¯ow) illustrate di ering approaches and complexity (Freeman, 1985;Fernandez, 1987;Blumenfeld and Bouchez, 1988;Ildefonse and Fernandez, 1988;Ildefonse et al, 1992;Nicolas, 1992;Jezek et al, 1996;Arbaret et al, 1997;Fernandez and Fernandez-Catuxo, 1997;Ildefonse et al, 1997). The absence of a generality emerging from these studies highlights the di culty of using shape-preferred orientations to uniquely describe even geometrically simple¯ows (Ottino, 1989).…”
