Rheology

View this topic in
Rheology is the study of the flow of matter: primarily in the liquid state, but also as 'soft solids' or solids under conditions in which they respond with plastic flow rather than deforming elastically in response to an applied force. It applies to substances which have a complex molecular structure, such as muds, sludges, suspensions, polymers and other glass formers (e.g. silicates), as well as many foods and additives, bodily fluids (e.g. blood) and other biological materials.

  • Continental Fault Structure and Rheology from the Frictional-to-Viscous Transition Downward

    Faulting is an expression of the interaction between rock rheology, kinematic boundary conditions, and associated stress fields. The structure and rheology of faults vary with depth, such that pressure-dependent frictional behavior predominating in the upper, brittle part of the crust is transitional to strongly temperature- and rate-dependent behavior in the lower part of the crust and mantle. This frictional-to-viscous transition (FVT) is characterized by changes in rock structure, rheology, and fluid activity that are closely tied to the earthquake cycle. As such, the FVT is a first-order decoupling zone, whose depth and lateral extent vary in time. Brittle, sometimes seismic, instabilities perturb the ambient stress field within the lithosphere on timescales ranging from seconds to years. These instabilities are measurable as transient motions of the Earth's surface and are manifest both at, and below, the FVT by the development of structural anisotropies (fractures, foliations). Surface motion studies of plate-boundary strike-slip faults indicate that shearing below the FVT is more localized in the lower crust than in the upper mantle. Structural investigations of exhumed shear zones reveal that this localization involves the nucleation of fractures at the FVT, as well as the buckling and rotation of existing foliations below the FVT. In some cases, rotation of these surfaces can initiate transient deformation, transferring stress upward and potentially triggering earthquakes. The networking of shear zones on several length scales allows them to function as decoupling horizons that partition three-dimensional strain within the lithosphere. The simplification of fault geometry with progressive strain lends justification to the use of laboratory-derived flow laws to estimate the bulk rock rheology on length scales at which strain is homogeneous. In general, the longer the timeand length scales of faulting considered, the greater the potential influence of the kinematic and thermal history on the rheology of the fault system. Taken together, studies suggest that future fault modeling must include parameters that quantify the thermal and structural aspects of rock history, as well as the fluid activity in and around faults.

  • Seismic Fault Rheology and Earthquake Dynamics

    As preparation for this Dahlem Workshop on The Dynamics of Fault Zones, specifically on the subtopic “Rheology of Fault Rocks and Their Surroundings,” we addressed critical research issues for understanding the seismic response of fault zones in terms of the constitutive response of fault materials. This requires new concepts and a host of new observations and experiments to document material response, to understand the shear localization process and the inception of earthquake instability, and especially to understand the mechanisms of fault weakening and dynamics of rupture tip propagation and arrest during rapid, possibly large, slip in natural events. We examine in turn the geological structure of fault zones and its relation to earthquake dynamics, the description of rate and state friction at slow rates appropriate to the interseismic period and earthquake nucleation, and the dynamics of fault weakening during rapid slip. The last topic gets special attention in view of the important recent advances in theoretical concepts and experiments to probe the range of slip rates prevailing during earthquakes. We then address the assembly of the constitutive framework into viable, but necessarily simplified, conceptual and computational models for description of the dynamics of crustal earthquake rupture. This is done principally in the slip-weakening framework, and we examine some of the uncertainties in doing so, and issues of how new understanding of the rapid large slip range will be integrated to model the traction evolution and the weakening process during large slip episodes.

  • Fluid Processes in Deep Crustal Fault Zones

    Fluid as a C-O-H dominated phase is widespread, but not ubiquitous, in the Earth's crust. The presence or absence of fluid is in large part a function of thermal history, at least up to the onset of melting. Rocks containing relatively low-temperature assemblages that are subject to further heating release fluid and so are commonly saturated, while rocks undergoing cooling resorb fluid into hydrous minerals and so are dry. Fluid may be introduced from external sources during faulting or magmatic activity, and the degree to which it persists depends on the interplay between injection rates and reaction rates. Where fluids do occur in the crust, fluxes are generally low, so that many aspects of fluid chemistry are dictated by saturation with rock- forming minerals. These mineralogical controls on fluid chemistry and activities of volatile species further affect the rheology of the crust by determining whether or not deformation can be fluxed by fluid processes. It is argued that rocks undergoing progressive metamorphism are wet and experience widespread deformation, while rocks that are cooling are strong and deformation is localized into zones, particularly during times of fluid infiltration. The transition between brittle and ductile behavior may therefore reflect changes in the availability of water rather than changes in temperature. Faults themselves are important loci of fluid flow, but it is often difficult to identify the sources of fluid, because geochemical tracers are mainly reset in a rock-dominated environment. Nevertheless, it is unlikely that faults are commonly effective drains of fluid being released by prograde metamorphism, because the very low permeability of such rocks (inferred from evidence for strong overpressuring) means that fluid cannot easily drain into fractures, even where a strong gradient in hydraulic head exists.
