Carbon-14 dating is not used for rocks, it is used for dating biological samples.  The ratio of Carbon-14 to the other forms of carbon is essentially constant while a plant or animal is alive because the carbon-14 is replenished from the atmosphere.  That stops when the plant or animal dies and the carbon-14 starts to decaying at a fixed rate while the other forms do not.
