By listening to the echo of earthquakes bouncing about inside our planet, we can make a good guess at what's inside Earth without slicing it up.
One source of variability occurs in low-density pockets of material some 3,000 kilometers below the surface, between the liquid iron alloy outer core and the mantle.
In this case the sample was heated using lasers and monitored via X-rays. The scientists were able to overcome a problem with previous experiments where high temperatures would cause the hydrogen containing the iron alloy to diffuse into the diamond.says geoscientist Sang-Heon Dan Shim"Argon does not react with the sample but suppresses hydrogen diffusion into diamond anvils, enabling us to achieve the extreme conditions in the laboratory.
