Steady state of microfabric elements

Different microfabric elements attain steady state at different strains. Grain SPO  attains steady state at shear strains of 1.5 and above, closely followed by the development of a stable domainal SPO at shear strains of about 3 and above. The last elements to attain steady state are grain size, fabric modifying mechanism assemblage and bulk texture. This confirms previous studies indicating that late changes in the strain field may be recorded in the grain or domainal SPOs of the microfabric, whereas texture and grain size reflect an older part of deformation history.
