Diffusion in feldspars undoubtedly takes place by many types of processes. A simplified distinction assigns movement down grain boundaries and through dislocations to non-volume diffusion, and movement through the near-perfect crystal units to volume diffusion (often called lattice diffusion). The former is only partly determined by the bonding properties of the crystal structure, and is strongly dependent on the grain size and on macroscopic imperfections. The latter is more strongly dependent on the bonding properties since it must depend principally on migration of atoms into point defects principally affected by neighboring atoms nearly in regular sites. Migration of an atom into a defect normally produces a new defect so that further opportunity for diffusion occurs. Over a long period of time at lower temperatures where new defects are not spontaneously produced, diffusion is reduced by migration of defects to sinks.
