The impact that formed the Moon's Orientale basin created a sea of melted rock 220 miles across and 6 miles deep, according to a new analysis. Similar seas of impact melt were probably present in at least 30 other large impact sites. Rocks formed as these basins cooled and solidified could mimic rocks formed very early in the Moon's history.
