Washington, Sept 20 : Geochemists at Rensselaer Polytechnic Institute have challenged the commonly held ideas about how gases are expelled from the Earth.

The team, lead by Prof E. Bruce Watson, has found strong evidence that argon atoms are tenaciously bound in the minerals of Earth’s mantle and move through these minerals at a much slower rate than previously thought.
