The so-called Fowler-Yang equations give an adequate description of this phenomenon (Fowler & Yang, 1999). This phenomenon has also been studied with Biotite and Feldspar (Barnett & Kerrich, 1980) and with quartz Arenites, which can serve as appropriate models for the highly quartz containing volcanic and magmatic stone material used in Inca walls.
