In some cases, the deposition of one type of protein can be experimentally induced by aggregated assemblies of other proteins that are rich in ?-sheet structure, possibly because of structural complementarity of the protein molecules.
32.
The presence of orthogonal jointing within the sheet structures at right angles to the plane of the sheet structures create access for moisture into joints resulting in enlargement of the joints and the ultimate fracture of the sheet into cubic, quadrangular or rhomboidal blocks which can become either individual or field of free-standing granite boulders of in height.
