    INTRODUCTION. Accessory minerals typically compose less than one modal percent of a whole-rock sample yet host significant fractions of the whole-rock budget of important trace elements and isotopes (Gromet Silver 1983 Bea 1996 Vervoot et al. 1996).One mineral in particular zircon has become an invaluable stop-off point on the journey of investigation into crustal evolution
