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.

Nettet1. okt. 2014 · A mobile bedload may enhance long-term erosion by quarrying mechanisms by promoting the growth of fractures and opening of joints in rock by percussion effects ( Whipple et al., 2000 ).

Nettet1. jan. 2013 · Channels that form in strongly jointed bedrock may have distinctive erosional processes and geometry relative to channels formed on weakly jointed bedrock because partially or completely detached blocks bounded by joints can be mobilized by flows in the channel (Hancock et al., 1998, Tinkler and Wohl, 1998).
