Figure 2

These three grains were recovered from the MAU-8 trachyte sample. Backscattered electron (BSE) images (a–c) of the three grains taken after completing all U–Th–Pb isotopic analyses. Cathodoluminescence (CL) images (d–f) taken prior to acquiring our SIMS data. The indicated analysis numbers correspond to those in Supplementary Data 1. The indicated ages are the radiogenic 207Pb/206Pb ages for the corresponding craters.
