Magma ocean discovery illuminates Earth’s extremely metal past – Inverse
For the first time, researchers find physical signatures of Earth’s primordial magma ocean.
Around 4.5 billion years ago,
Earth was probably one big ocean of magma. Geologists who study this primordial Earth use models, experimental simulations, and even samples from the Moon to figure out what the planet was likely like during the early days of the Solar System.
But finding physical evidence on Earth that confirms these models has been challenging. In a study published Friday in Science Advances, geologists announce theyve found a direct signature of the primeval magma ocean in a famously…
