|Definition :||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.|
|Relationship with the substrate :||The plane of detachment of the scales is located near the
stone surface (a fraction of milliimeters to several centimeters).
|Equivalent terms to be found in other glossaries :||Desquamation, Scale, plaque or plaquette describe exclusively
the features, and not the process.
|Other orthograph :||NA|
|Sub-type(s) :||- Flaking : scaling in thin flat or curved scales of submillimetric to millimetric thickness, organized as fish scales.
- Contour scaling : scaling in which the interface with the
sound part of the stone is parallel to the stone surface. In the case of flat surfaces, contour scaling may be called spalling.
Case hardening is a synonym of contour scaling.
|Not to be confused with :||- Delamination : corresponds to a detachment following the
bedding or shistosity planes of a stone.
