Carbon dating million years
Some are found in these pipes, such as kimberlites, while other diamonds were liberated by water erosion and deposited elsewhere (called alluvial diamonds).
According to evolutionists, the diamonds formed about 1–3 billion years ago.
ICR creationists claim that this discredits C-14 dating. Answer: It does discredit the C-14 dating of freshwater mussels, but that's about all.
Kieth and Anderson show considerable evidence that the mussels acquired much of their carbon from the limestone of the waters they lived in and from some very old humus as well.
When an organism, eg a tree, dies it stops taking in carbon dioxide.
The amount of carbon-14 in the wood decreases with time as it decays into nitrogen with a half-life of about 5700 years.
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.
When the organisms die, they stop incorporating new C-14, and the old C-14 starts to decay back into N-14 by emitting beta particles.Diamond is the hardest substance known, so its interior should be very resistant to contamination.
