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 is the net passive movement of particles (atoms, ions or. molecules) from a region in which they are in higher concentration to. regions of lower concentration. It continues until the concentration of. substances is uniform throughout. Some major examples of diffusion in biology: â¢ Gas exchange at the alveoli â oxygen from air to blood, carbon. dioxide from blood to air. â¢ Gas exchange for photosynthesis â carbon dioxide from air to. leaf, oxygen from leaf to air.
