Carbon 14 dating is reliable for rocks that are

Carbon-14 comes from nitrogen and is independent of the carbon-12 reservoir.If even a small percentage of the limestone deposits were still in the form of living marine organisms at the time of the Flood, then the small amount of carbon-14 would have mixed with a much larger carbon-12 reservoir, thus resulting in a drastically reduced ratio.Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty of accuracy.Absolute dating provides a numerical age or range in contrast with relative dating which places events in order without any measure of the age between events.While there is no proof that the rates were different in the past than they are today, there is also no proof that they were the same.

If the clock is not set to zero when a deposit forms, then there can be no starting point from which to calculate the age of a deposit.

Some scientists argue that the magnetic field of the earth has declined over time.

c) Atmospheric carbon forms just 0.0005% of the current carbon reservoir—99.66% of the earth's carbon exists in limestone, 0.31% in oil and gas, and 0.02% in coal.

Specimens would then look much older than they actually are.

d) Even if the rate of decay is constant, without knowledge of the exact ratio of carbon-12 to carbon-14in the initial sample, the dating technique is subject to question.
