Are you suggesting that there is some process that could act upon the interior of a sample that has never been exposed to the atmosphere or ground water since its formation? Exterior surfaces and the internal surfaces of cracks and fissures, sure. But what about internal areas that have been completely sealed from all external processes? Granted, it's sometimes hard to find such an area to test if the sample is small and extremely old, but in those instances we can readily tell if we have a good sample or not and know if our dating methods will be valid in that particular instance.
