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 is diffusion using carrier or channel proteins in the cell membrane that assist in the movement of molecules across a concentration gradient. The third type of movement is known as osmosis, or the movement of water to equalize solute concentration.
