Contrast relative dating and radiometric dating

The problems are particularly great at about 10,000 14C y.a., when a large influx of 14C-depleted carbon from the oceans, combined with a decrease in the rate of 14C production at the top of the atmosphere, gives an 'age plateau' such that the same 14C age covers a wide span of real time, about 1,000 years. U/Th) can be used to attempt to check the 'true' age of specimens or sediment layers dated by 14C, although these all have substantial error margins of their own.

The most convincing way to check the 14C age scale is through biological or sedimentological features which build up annual layers over long periods of time (e.g.

The uncertainty in the varve chronology comes from two sources: core sampling and varve counting. Since the varve ages from below 18 m (corresponding to ca.At the extremes there is a range from 10,447 to 11,700 year B. And evidence that properly conducted C14 radiometric dating can approach reasonable accuracy, possibly within better than 10 percent.Also C14 dating affirms Scripture/Scripture affirms C14 dating!When these one-cell algae die, they drift down, shrouding the lake floor with a thin, white layer.The rest of the year, dark clay sediments settle on the bottom.
