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.
Research led by the California Institute of Technology has revealed that a 2-billion-year-old carbon footprint may have resulted not from a global crisis, but from local magma movements in Karelia. The findings are based on the analysis of rock samples taken from the Zaonega Formation.
Caltech-led research has shown that the 2-billion-year-old carbon isotope anomaly may have resulted from local magma activity rather than a global catastrophe.
Scientists have questioned the idea that a significant chemical trace in Earth's oxygenation process resulted from a global environmental catastrophe. According to new research, this trace may be the result of magma movements and associated gas formation occurring in a limited region.
