Over the last six years, improvements in measurement techniques and highly detailed lunar orbiter maps of the magnetized lunar crust sparked Weiss, Tikoo and other scientists to reexamine the Apollo rocks for new clues. (sciencenews.org)
This vast volcanic plain appears to contain some of the youngest lava flows on the moon, as well as rocks ejected by impacts that could be parts of the buried lunar crust. (newscientist.com)
The new, younger age obtained for the oldest lunar crust is similar to ages obtained for the oldest terrestrial minerals — zircons from western Australia — suggesting that the oldest crusts on both Earth and Moon formed at approximately the same time, and that this time dates from shortly after the giant impact.
