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).
Facilitated diffusion: Spontaneous passive transport of ions or molecules across a cell membrane (different because it happens outside the active phase of osmosis or intracellular diffusion). Gaseous diffusion: Used mainly with uranium hexafluoride to produce enriched uranium for nuclear reactors and weapons.
