Ancient Chemical Fingerprint Points to Pre-Collision Earth Remnants Deep Within Planet
Researchers have identified a chemical signature in ancient rocks that appears to predate the massive meteorite impact that formed the Moon. The discovery suggests remnants of the original Earth may have survived deep within the planet for billions of years, according to a new study published in Nature Geoscience.
Proto-Earth’s Chemical Signature Survived Planetary Transformation
Scientists have discovered what appears to be preserved material from the primordial Earth that existed before the giant impact that created the Moon, according to a new study published in Nature Geoscience. The finding challenges long-held assumptions about how completely our planet was transformed by the collision that occurred approximately 4.5 billion years ago.
