Magma and microbial activity may rewrite a 2-billion-year-old carbon signal
Scientists have found that a famous 2-billion-year-old chemical signature, once thought to record a massive global change in Earth’s carbon cycle, may instead have been produced by local magma, hydrocarbons, and methane-eating microbes. The discovery raises new questions about what was really happening as oxygen transformed the young planet.
