Scientist reveals Earth's golden core

An Australian scientist has released new calculations which he believes indicate a vast quantity of gold present at the Earth's core.

Professor Bernard Wood of Sydney's Macquarie University has published the findings of his investigation in the journal Nature.

By his calculations, the Earth's core contains enough gold to cover the surface of the globe to a half a metre thickness, ABC News Online reports.

Professor Wood, a geologist, and his research team investigated the development of the earth from its molten metal core and compared it to the composition of meteorites to calculate the amount of gold present.

He told ABC: "This tells us that the Earth is chemically very similar to those meteorites but the Earth's crust is depleted in all those elements that like to dissolve in iron.

"We can say that more than 99 per cent of the Earth's gold is in the core."
