U-Pb Ages and Compositions of Apollo 14 Regolith Glasses

U-Pb compositions of Apollo 14 impact glasses suggests two prominent age groups at 3.7 Ga and less than 1 Ga, with smaller clusters at 2.5 Ga and 1.3 Ga. The range of chemical compositions suggests multiple impact events contributed to these groups.
