Thermoluminescence dating accuracy

The methods that are used depend on the presumed age of the site from which they were excavated.For instance, if a site is believed to be over 100,000 years old, dendrochronology and radiocarbon dating could not be used.

Specifically, the electrons of quartz, feldspar, diamond, or calcite crystals can become displaced from their normal positions in atoms and trapped in imperfections in the crystal lattice of the clay molecules.

Following death, however, no new carbon is consumed.

Progressively through time, the carbon-14 atoms decay and once again become nitrogen-14.

It will often work well with stones that have been heated by fire.

The clay core of bronze sculptures made by lost wax casting can also be tested.
