Of course C-14 would never be of any use for dating bearing deposits, unless you want everything to date to around 40,000 years! How do you know which dates are correct? When the original sample of the volcanic tuff was given to the laboratory, the potassium-argon date was about 230 million years. Researchers will also send samples to different labs, ensuring that each is unaware of which other labs are carrying out tests.

This can be used in conjunction with the other principles listed here - Superposition see below and Lateral Continuity see above. It says nothing about the age of each layer, merely the sequence of deposition. This is used to date volcanic rock to the time the volcano erupted. If the ages are so uncertain for the Moon, what about the ages of Mars and Mercury?

RADIOMETRIC TIME SCALE - The Christian Creationists have criticized it on the grounds that it is inaccurate. Similarly, after 30 half-lives, roughly one part in one billion will remain, and after 40 half-lives, roughly one part in one trillion will remain, which is near the current limit of detectability.
