In short, the answer is… sometimes. Thank you for subscribing. May 29, Geological Evolution of North America, 3rd Edition.
Even so, the missing rings are a far more serious problem than any double rings.
ERRORS ARE FEARED IN CARBON DATING
These bands are thousands of kilometers long, they vary in width, they lie parallel, and the bands on either side of any given ridge form mirror images of each other. How do we know this? More from Earth Sciences. Radiocarbon dating doesn't work well on objects much older than twenty thousand years, because such objects have so little C left that their beta radiation is swamped out by the background radiation of cosmic rays and potassium K decay.
