Story summary
- The Jericho kimberlite study in northern Canada finds that at least 8.2 percent carbon dioxide is needed for magma buoyancy to lift diamonds from depths over 93 miles.
- The research, led by Ana Anzulovic of the University of Oslo, shows how water and carbon dioxide influence the magma's lift.
- Without sufficient carbon, the melt becomes denser than surrounding rock and fails to erupt, guiding exploration strategies for kimberlite pipes.
