Cherniak (2010b) reviews diffusion in the accessory minerals zircon, monazite, apatite, and xenotime, phases important in geochronologic studies. Diffusion in other minerals, including carbonates, sulfide minerals, fluorite and diamond, is reviewed by Cherniak (2010c).
Diffusion, also known as migration, is the scientific name for the intermingling, or mixing, of the atoms, molecules or ions of two different substances in contact with each other. The substances can be gases, liquids or solids, and diffusion is the result of random thermal motion of their particles.he particles of a substance are in continuous, random motion in every direction, but there is a net flow of particles down the diffusion gradient or, in other words, from the area of higher concentration to the area of lower concentration.
