Carbon dating years

But, carbon dating can't be used to date either rocks or fossils.It is only useful for once-living things which still contain carbon, like flesh or bone or wood.The table orders them chronologically, based on 14C age.Many of the date ranges provided are actually two date ranges, for example the Habakkuk Commentary (#13), which is given as 160-148 or 111-2 CE.Rocks and fossils, consisting only of inorganic minerals, cannot be dated by this scheme.Carbon normally occurs as Carbon-12, but radioactive Carbon-14 may sometimes be formed in the outer atmosphere as Nitrogen-14 undergoes cosmic ray bombardment.The results from the latter two were almost identical, which is a good indicator of the basic accuracy of this dating method.

With the exception of the first text from Wadi-ed-Daliyeh, the texts in the table below are only those from the caves around Qumran.The section of the calibration curve for the 14C age of the Habakkuk Commentary is complex, so that the 14C age of 2054 cuts through a few spikes on the curve, providing two date ranges.The Great Isaiah Scroll 1QIsa has been tested three times, once by Libby, once at Zurich and once at Tucson.In reality, its measured disequilibrium points to just such a world-altering event, not many years ago.Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.
