and proposed a new mechanism for a way younger volcanos took shape on the cooling moon 2 billion years ago.

Scientists previously speculated that the elevated water content or radioactive elements in the lunar interior might have driven volcanism in the late stage of the moon’s life

The study published on Saturday in the journal Science Advances showed that the mantle melting-point depression due to the presence of fusible, easily-melted components could generate young lunar volcanism

The researchers from the Institute of Geology and Geophysics of the Chinese Academy of Sciences (IGGCAS) scrutinized 27 Chang’e-5 basalt clasts to calculate the original ingredients of those samples.

They found that the young Chang’e-5-source magma might have higher calcium oxide and titanium dioxide contents than magmas in older samples returned by the Apollo Missions.

ruling out the theory that the moon has been geologically dead after the formation of Apollo samples at least 3 billion years ago.

Recent lunar mantle melting can be achieved by either raising the temperature or lowering the melting point,” said the paper’s corresponding author Chen Yi, an IGGCAS researcher.
