Helium dating

None of the rocks are concordant in these two ages; all have lost helium.The uranium-helium "ages" are best described, on the average, as equal to 74% of the K sbnd Ar ages minus 0.2 m.y.

Uranium-helium "ages" have been determined for a suite of 25 whole-rock basalts from Madeira and Porto Santo islands in the Madeira Archipelago.

Uranium and thorium in zircons produce helium as a by-product of their radioactive decay. Helium diffusion rates support accelerated nuclear decay.

Using the helium dating technique, the team was able to determine the age of the zircon crystals and cross match that with the known age of the kimberlite layers in Australia.

The result is an ongoing map of where the low-helium, diamond-rich deposits most likely exist underground – the most likely source of the hidden diamonds that so many have looked for in the Northern Territory for so long.
