- In mining, polished and striated surfaces of the rock, often seen on the walls of fissure-veins, and the result of motion. under immense pressure, of parts of the country-rock, or of the mass of the vein itself. Well-developed slickensides are most frequently seen in connection with mineral veins, but the sides of Joints in non-metalliferous rocks occasionally exhibit this kind of striation. Slickensided surfaces are frequently coated with a thin film of pyrites, galena, hematite, or some other mineral, which may be polished so as to reflect the light like a mirror (whence the French name miroirs).

Examples
“The fawn-grey colour, here shining as if polished by "slickensides," there dull and roughened by the rude touch of Time, is a neutral ground that takes all the tints with which sun and moon, mist and cloud, paint and glaze the world: changeable as the chameleon's, the coating is never the same for two brief hours.”
“The second fault, below, shows oblique-slip slickensides, and beneath the slickensides, in the footwall, are some calcite masses and a footwall breccia.”
“Bedded veins may be distinguished from fissure veins by the absence of all traces of a fissure, the want of a banded structure, slickensides, selvages, etc.; from gash veins and the floors of ore which often accompany them, as well as from segregated veins, they are distinguished by the nature of the inclosing rock and the foreign origin of the ore.”
“Drill hole three cut a 86 metre wide, strongly fractured and altered graphitic-pyritic pelite unit containing fracturing, grey clay and slickensides.”
“The fawn-grey colour, here shining as if polished by “slickensides,” there dull and roughened by the rude touch of Time, is a neutral ground that takes all the tints with which sun and moon, mist and cloud, paint and glaze the world: changeable as the chameleon’s, the coating is never the same for two brief hours.”
