WebCleavage is a super-induced structure, the result of pressure acting on the rock at some time when it was deeply buried beneath the Earth’s surface. On this account, slates occur chiefly among older rocks, although some occur in regions in which comparatively recent rocks have been folded and compressed as a result of mountain-building movements. WebSep 4, 2024 · Cleavage is a profound property that results from a mineral's molecular structure, and cleavage is present even when the mineral doesn't form good crystals.
