The world’s largest oceanic plateau formed more than 100 million years ago, but scientists have now found the ancient magma pathways still hidden beneath it

Scientists uncovered ancient magma pathways beneath the Ontong Java Plateau.

These hidden dike swarms reveal how enormous magma volumes traveled through the lithosphere.

Seismic waves passing through the plateau showed unusual behavior.

This behavior indicated a hybrid internal structure with vertical dike-like formations.

These preserved dike swarms permanently reshaped the surrounding rocks over geological time.
