An interesting read on the origins of this precious metal on the surface of planet Earth.

Ultra high precision analyses of some of the oldest rock samples on Earth by researchers at the University of Bristol provides clear evidence that the planet's accessible reserves of precious metals are the result of a bombardment of meteorites more than 200 million years after Earth was formed.

(The research is published in Nature.)

The full load of meteorite gold was thus added to the mantle alone and not lost to the deep interior.

Good to see you are posting once again Huego.

I often question on how accurate the dating of geology and the universe is using our human methods.
