Violent meteorite impacts forged parts of the lunar crust

Science
May 11 (UPI) -- Parts of the moon's crust were forged by large and violent meteorite impacts, according to new research published Monday in the journal Nature Astronomy. Analysis of a lunar rock, brought home by astronauts on NASA's 1972 Apollo 17 mission, revealed the presence of minerals that can only form at temperatures greater than 4,300 degrees Fahrenheit -- the kind of temperatures generated by large impact events. Researchers found evidence of a specific phase of cubic zirconia inside the lunar rock, a phase only produced at high temperatures. The mineral has since reverted to baddeleyite, but the signature of its cubic zirconia phase remains imprinted in the structure of the baddeleyite crystals. Scientists were able to date the baddeleyite to 4.3 billion years ago, which sugges...
