Water Was Fueling Earth’s Volcanoes 3 Billion Years Ago - Scientists Bigges Historical Fear

More than 3.1 billion years ago, water was already traveling deep into Earth and helping generate magma beneath what is now Western Australia.

In this DiscoverTube investigation, we explore ancient volcanic rocks from the Pilbara Craton that preserve evidence of water-rich mantle melting long before modern plate tectonics may have been fully established.

The research points to a process called dripduction — a possible early form of crustal recycling that carried hydrated rock downward, released water into the mantle and helped fuel ancient volcanism.

The discovery could change how scientists interpret some of Earth’s oldest volcanic rocks — and how our planet first learned to recycle its crust and water.
