...Romain Tartèse; Mahesh Anand; Thomas Delhaye Abstract In this study, we carried out Pb/Pb dating of tranquillityite in high-Ti mare basalts 10044, 75055, and 74255, using a Cameca NanoSIMS 50 at a spatial resolution of ~3 μm. The analyses yielded 207 Pb/ 206 Pb dates of 3722 ± 11 Ma for sample...
