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 most frequently appear as joint sets and systems. A joint set is a family of parallel, evenly … 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, or shrinkage caused by the cooling or desiccation … 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 are classified by their geometry or by the processes that formed them.
