Looking for Helium [...]

Helium doesn’t just make your voice squeaky – it is critical to many things we take for granted, including MRI scanners in medicine, welding, industrial leak detection and nuclear energy.  However, known reserves are quickly running out. Until now helium has never been found intentionally – being accidentally discovered in small quantities during oil and gas drilling.

Now, a research group from Oxford and Durham universities, working with Norway-headquartered helium exploration company Helium One, has developed a brand new exploration approach. The first use of this method has resulted in the discovery of a world-class helium gas field in Tanzania.

Their research shows that volcanic activity provides the intense heat necessary to release the gas from ancient, helium-bearing rocks. Within the Tanzanian East African Rift Valley, volcanoes have released helium from ancient deep rocks and have trapped this helium in shallower gas fields. The research is being presented by Durham University PhD student Diveena Danabalan at the Goldschmidt geochemistry conference in Yokohama, Japan. (Source)
