只有当高母/子体比值矿物具有快的放射成因同位素扩散速率时，才能够应用合理的矿物等时线确定变质再造的时间。
Valid mineral isochrons can be expected to date the timing of metamorphic resetting only if the mineral of high parent / daughter ratio has fast rate of radiogenic isotope diffusion during the metamorphic resetting .

前人关于花岗岩类的研究主要集中于北大别，本文系统地研究了其他构造单元花岗岩类的年代学，主、微量元素和放射成因同位素地球化学。
Previous studies on granitoids in the Dabie orogen mainly focused on the North Dabie Zone . In this study , a systematic study on the geochronology , major and trace elemental chemistry , and radiogenic isotope composition of granitoids from other units of the Dabie orogen was conducted .
