Ancient Potassium Isotopes Reveal Earth’s Primordial Past, Scientists Report
Scientists have identified rare chemical signatures in ancient rocks that appear to predate Earth’s catastrophic formation. The findings suggest remnants of the original proto-Earth survived the giant impact that created our modern planet.
Chemical Traces of Ancient Earth Discovered
Researchers from MIT and international institutions have reportedly uncovered chemical evidence of material that existed before Earth’s catastrophic formation, according to a recent study published in Nature Geoscience. The discovery challenges long-standing assumptions about the complete destruction of proto-Earth material during the planet’s violent early history.
