How far back does radiocarbon dating go
WebBy using another dating method (dendrochonology, radiocarbon dating) to obtain the absolute date of an archaeological feature (such as a hearth), and measuring the direction of magnetism and wander in the clay today, it is possible to determine the location of the magnetic north pole at the time this clay was last fired. WebIn theory radiocarbon dating can go back around 100,000 years, but it is really unreliable past 75,000 years. I don't know the chemistry behind it, but as I understand it we know that simply because, based on the rate of decay of the Carbon-14 isotope.
