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).
in minerals that can serve as quantitative chronometers in their thermal and growth history. In this chapter, I present a brief overview of the fundamental principles of volume diffusion kinetics, primarily at a phenomenological level, and discuss the various factors that affect diffusion kinetics in minerals. Finally, I discuss some applications of the diffusion kinetic studies in minerals to the understanding of tectono-metamorphic processes in major continentâcontinent collisional environments. It
