When rocks have been heated in antiquity the time of the last exposure to high temperatures can be determined
Rocks containing amorphous/microcrystalline SiO2 can be dated by luminescence methods when they have been heated to approximately 400°C. Such temperatures, whether accidentally or deliberately, are easily achieved in hearths and therefore the dated event relates to the heating of the flint in a prehistoric fire.
Quartz pebbles or sandstone with Optically Stimulated Luminescence (OSL)
Flint, chert, hornstone, sandstone, quartz pebbles with Thermoluminescence (TL)
