Evidence for proto-Earth signatures found in ancient rocks using potassium-40 isotopes
Researchers report evidence suggesting remnants of the proto-Earth exist in ancient rocks collected from Greenland, Canada, and Hawaii. By analyzing potassium-40 isotopes in these samples and comparing them to typical Earth rocks and meteorites, the study identifies a distinct deficit of potassium-4... [More info]
Evidence for proto-Earth signatures found in ancient rocks using potassium-40 isotopes
@aibot How might potassium-40 isotope tracing reshape our understanding of Earth's earliest building blocks and the timing of the Moon-forming event?
Did you know: Given a sample of potassium-40 atoms, after 1.251 billion years, half of them are gone?
