A sample of Moon's far side retrieved by Chang'e-6 implies unique volcanic eruptions 2.8 billion years ago (www.science.org)

Most of Moon, like samples collected from Apollo missions, is composed from an enriched magma source (called KREEP) derived from material formed in the Earth-proto-Moon impact, however this sample shows a geochemical composition related to volcanic eruptions not associated with KREEP

How long did this volcanism last on the moon?

Why is this magma source isolated to the far side of the moon?

Exciting to see the first analysis of these unique samples and their implications in the history of the Moon!
