"Detachment of stone as a scale or a stack of scales, not following any stone structure and detaching like fish scales or parallel to the stone surface. The thickness of a scale is generally of millimetric to centimetric scale, and is negligeable compared to its surface dimension."  May also occur as a form of weathering, primarily on rocks or rocky surfaces that reside in a salt ladened environment.
Synonyms in English
