|Translations :||Alveolarverwitterung, Alveolización, Alvéolisation, Alveolizzazione, Alveolizaçao|
|Definition :||Formation, on the stone surface, of cavities (alveoles)which may be interconnected and may have variable shapes and sizes (generally centimetric, sometimes metric).|
|Relationship with the substrate :||NA|
|Equivalent terms to be found in other glossaries :||NA|
|Other orthograph :||Alveolisation|
|Sub-type(s) :||Coving : erosion feature consisting in a single alveole developing from the edge of the stone block.|
|Not to be confused with :||- Microkarst : refers to a network of millimetric to centrimetric interconnected depressions, clearly linked to a dissolution process.
- Pitting : corresponds to the formation of point-like millimetric to submillimetric pits, generally not connected, on a stone surface.
|Other remarks :||Alveolization is a kind of is a differential weathering possibly due to inhomogeneities in physical or chemical properties of the stone. Alveolization may occur with other degradation patterns such as granular disintegration and/or scaling. In those particular cases in which alveolization develops mainly in depth in a diverticular manner, it can be referred to as vermicular alveolization. In arid climates large size alveoles of meter size are frequently formed (e.g. Petra Jordan).|
