By nature, brittle deformation is discontinuous. It is often studied through mechanical tests, both in laboratories and outdoors, in mines and quarries. Brittle deformation also concerns civil engineering (road maintenance, strength of retaining stru

This chapter is particularly devoted to microscopic scale fabrics. Fabrics can be defined as the spatial and geometrical configurations of all components that are contained in a rock. These components are penetratively and repeatedly developed throug

This book, based on laboratory, teaching and field experience, has a strong focus towards hard rocks and magmatic rocks, from both the continental crust worldwide, where quartz and granites are dominant, and the mantle dominated by olivine in peridot

The discontinuous nature of brittle behavior contrasts with the apparent continuous nature of ductile deformation. Continuity is obviously scale dependent. Faults and fractures are common features of discontinuous deformation. They are particularly a

Principles of Rock Deformation and Tectonics
This chapter widens our scope towards translation and rotation. These displacements are critical in tectonic studies along with distortion, which has so far been the main subject of this book. Note that a translation needs a fixed reference to be def

Principles of Rock Deformation and Tectonics
The fundamentals of structural geology are presented, namely, folds, planar structures (cleavage or schistosity, foliation) and linear ones (lineations), regarded as emblematic for geologists. Ductile imprints of folds, affecting stratified formation

Some structural geological exercises performed by geologists are presented in this chapter. Many of the practical problems are related to the orientation of planes, lines or principal stress directions. We have chosen to pay particular attention to t

In contrast to the elastic deformation, which is reversible, usually neglected by field geologists but important for geophysicists working in seismology, ductile deformation is irreversible. This chapter is restricted to solid materials. Materials co

A magma is a two-phase material made of crystals immersed in a silicate melt, which displays a high viscosity contrast between the liquid and the solid fractions. A specific rheological behaviour is therefore expected from such a material, particular
