Abstract
The critical evaluation of the kinematic significance of natural geological deformation structures, with particular reference to the determination of shear-sense, requires a high degree of familiarity with the basic concepts of flow, and the influence of material properties ( discontinuities, rheological layering, anisotropy) on the nature of flow at the local scale. This contribution begins with a chapter on flow, followed by three chapters which critically examine geological deformation structures which are commonly used as shear-sense indicators: foliations, stiff inclusions and their attendant wings and, finally, folds and veins.Keywords
