Surges in volcanic activity on the Moon about two billion years ago

H. Tian, C. Zhang, et al.

The Chang'e-5 mission has unveiled the youngest lunar basalts, shedding light on the Moon's late-stage evolution. With a focus on olivine and pyroxene crystals, the findings suggest limited magma recharge and reveal a significant magmatic flux around 2 billion years ago, providing fresh insights into lunar thermal evolution. This groundbreaking research was conducted by Heng-Ci Tian and colleagues.

Abstract

The Chang'e-5 mission returned the youngest lunar basalts, providing insights into the Moon's late-stage evolution. Analysis of olivine and pyroxene crystals reveals mostly normal zoning, suggesting limited magma recharge. Thermal modeling indicates enhanced magmatic flux around 2 billion years ago, implying episodic eruptions with above-average fluxes during the Moon's final volcanic stage, revising models of lunar thermal evolution.
