... analysis (∼15 μm) and high spatial resolution (∼2 μm) scanning ion imaging of Pb isotopes have been applied in an attempt to quantify the effects of metamorphism. Spot analyses spread along concordia yielding 207 Pb/ 206 Pb ages from 2.5 Ga to 3.9 Ga, with the oldest grains reversely discordant. Ion images...

... arise in SEM-CL images by using a scanning electron beam when phosphorescence occurs, e.g. due to a long life time (τ) of the excited state. The time gap between excitation and emission of the luminescence causes luminescence ‘afterglow’ (cf. Fig. 8 ). Minerals, which often show phosphorescence effects...
