Reaction along cleavage planes is also likely to have been comparatively fast because nucleation and growth were promoted by rapid diffusion, particularly if melt is present as in this case. Substitution of Si in hercynite of the porphyroblast, particularly in rims that are in contact with glass and inclusions of glass, hint at growing in contact with the melt.

Portal:Minerals - Wikipedia

Cleavage, in mineralogy, is the tendency of crystalline materials to split along definite crystallographic structural planes. These planes of relative weakness are a result of the regular locations of atoms and ions in the crystal, which create smooth repeating surfaces that are visible both in .

Cleavage: Mineral Properties - The Mineral and Gemstone .

A cleavage plane is a plane of structural weakness along which a mineral is likely to split smoothly. Cleavage thus refers to the splitting of a crystal between two parallel atomic planes. Cleavage is the result of weaker bond strengths or greater lattice spacing across the plane in question than in other directions within the crystal.
