A number of features of zircon (ZrSiO4), including high U-Th concentrations, high abundance in a wide range of lithologies, refractory nature under metamorphic and some magmatic conditions, and resistance to physical and chemical weathering, make it highly suitable for geochronology and thermochronology and thus a versatile tool for examining a wide range of earth processes. Like apatite and many other minerals, radioisotopic dating of zircon was first performed using the (U-Th)/He system, but the thermochronologic significance of zircon He ages has emerged only in the last few years. In this chapter, I review the current status of zircon...
