Image from the Kazakh Uplands in Balkhash District, Kazakhstan. Orthogonal joint sets on a bedding plane in flagstones, Caithness, Scotland. Se mer A joint is a break (fracture) of natural origin in a layer or body of rock that lacks visible or measurable movement parallel to the surface (plane) of the fracture ("Mode 1" Fracture). Although joints can occur singly, they … Se mer Joints are classified by their geometry or by the processes that formed them. By geometry The geometry of … Se mer Some fractures that look like joints are actually shear fractures, which in effect are microfaults. They do not form as the result of the perpendicular … Se mer • Basalt fan structure • Exfoliating granite • Tessellated pavement Se mer Joints arise from brittle fracture of a rock or layer due to tensile stress. This stress may be imposed from outside; for example, by the stretching of layers, the rise of pore fluid pressure, … Se mer Joint propagation can be studied through the techniques of fractography in which characteristic marks such as hackles and plumose structures are used to determine propagation directions and, in some cases, the principal stress orientations. Se mer Joints are important not only in understanding the local and regional geology and geomorphology but also in developing natural … Se mer
