Descoperirea din Rusia care schimbă tot ce știam despre Pământ. Cercetătorii admit că au greșit o teorie veche

Researchers challenge a long-standing interpretation of a global carbon cycle disruption event that occurred around two billion years ago. This period marked significant oxygen accumulation in Earth's atmosphere, leading to the burial of microbial material under the sea, which captured carbon in rocks. A study suggests that the unusual isotopic signature found in rocks from the Zaonega Formation in Russia may be due to local processes rather than a global event. The study indicates that magma intrusion heated organic-rich sediments, generating hydrocarbons that were consumed by nearby microorganisms, producing a specific isotopic signature. The findings raise questions about the global significance of the Shunga-Francevillian event, prompting further investigation in Gabon.
