Thus they probably formed at a depth of 100–200 km.

Geologists believe that the ones we find must have been transported supersonically to the surface, in extremely violent eruptions through volcanic pipes.

This procedure of radiocarbon dating has been widely adopted and is considered accurate enough for practical use to study remains up to 50,000 years old.

Because the ratio of carbon 12 to carbon 14 present in all living organisms is the same, and because the decay rate of carbon 14 is constant, the length of time that has passed since an organism has died can be calculated by comparing the ratio of carbon 12 to carbon 14 in its remains to the known ratio in living organisms. Our Living Language : In the late 1940s, American chemist Willard Libby developed a method for determining when the death of an organism had occurred.

C at all if they really were over a billion years old, yet the radiocarbon lab reported that there was over 10 times the detection limit.

Thus they had a radiocarbon ‘age’ far less than a million years!
