The planar shape of rock joints
WebbColumnar jointing is produced by cooling of lava flows, ash-flow tuffs, and other bodies of magma or lava. Cooling causes contraction which in turn causes fracturing. Fractures … Webbfaults, joints or the interface between bedrock and an overlying layer of weathered rock. Block sliding along a single plane (Figure 2) represents the simplest sliding mechanism. …

Webb19 maj 2024 · Joints are geologic structures that result from the cracking of rocks along planes of weakness, without significant displacement of the rocks. Joints can be caused by a variety of processes, such as cooling, drying, and tectonic forces. Webbbedding are termed bedding joints or bedding plane joints. Those fractures parallel to metamorphic foliation are called foliation joints. 2. Bedding plane separation.— A …
