New research has uncovered new evidence to suggest that Earth is leaking gases from deep inside its mantle, even in regions without any volcanic activity. The study reveals that gases including helium and argon are slowly seeping hundreds of kilometres up through Earth’s crust. The highest amount of gas was found in the oldest and deepest groundwater samples – some over 20,000 years old – indicating the gases have been moving slowly but steadily over a long period of time.
