SLICKENSIDES, a miner's term for the striæ, furrows, or polished surfaces covering the walls of fissures, and sometimes the surfaces of bed rock. They result from the friction of two portions of rock moving one against the other under great pressure. The occurrence is common, being often found on the walls of faults and joints.
