Core Viewpoint - The research conducted on lunar samples from China's Chang'e 5 and Chang'e 6 missions reveals that the Moon experienced volcanic activity much later than previously believed, challenging the notion that it became "dormant" 3 billion years ago [1][2]. Group 1: Research Findings - The study identified two types of basalt from the Chang'e 6 samples, formed around 2.8 billion and 2.9 billion years ago, with distinct compositions and sources: one type originates from deep within the lunar mantle (over 120 kilometers), while the other comes from a shallower mantle (60-80 kilometers) [1][2]. - The research team proposed a new thermal dynamic mechanism for lunar volcanism, suggesting that as the Moon cooled, its lithosphere thickened, trapping magma in the shallow mantle, which could then transfer heat upward, leading to volcanic eruptions [2]. Group 2: Implications and Broader Context - The findings not only revise the understanding of the Moon's thermal evolution history but also provide significant insights into the volcanic activity mechanisms of other small, airless celestial bodies [3].
