Chang'e-6 Reveals Lunar Far Side's Volcanic History and Ancient Magnetic Field

China's Chang'e-6 mission returned 1,935.3 grams of lunar far-side samples from the South Pole-Aitken Basin in 2024, revealing evidence of volcanic activity lasting 1.4 billion years, an ancient magnetic field, lower water content than the near side, and a precise formation date of the basin at 4.25...

Chicxulub Impact, Not Volcanism, Primarily Caused Cretaceous-Paleogene Extinction

A new study using fossil molecule analysis in North American sediments concludes that the Deccan Traps volcanism, though causing a temporary 5-degree Celsius cooling 30,000 years before the Chicxulub impact, did not cause the Cretaceous-Paleogene mass extinction; the impact was the primary cause.

Volcanic Activity and Continental Growth Increased Atmospheric Oxygen Before the Great Oxidation Event

A Japanese research team's study, published in Communications Earth & Environment, used numerical modeling to demonstrate how intense volcanism and continental growth during the late Archean Eon increased atmospheric oxygen levels before the Great Oxidation Event by enriching oceans with nutrients a...
