Question

which dating method provides dates between 40,000 and 100,000 - 300,000 years ago, and enables us to determine the date when ancient pottery fragments were last fired, or when burnt - flint artifacts last were heated?

thermoluminescence
electron - spin resonance
dendrochronology
radiocarbon dating

Explanation:

Thermoluminescence dating is used for dating materials like ancient pottery fragments (last - fired date) or burnt - flint artifacts (last - heated date). It is effective in the range of 40,000 to 100,000 - 300,000 years ago. Electron - spin resonance has different applications (e.g., dating fossils in a different context). Dendrochronology is based on tree rings and is mainly for much more recent (hundreds to thousands of years) and organic (wood) materials. Radiocarbon dating is typically used for organic materials up to about 50,000 years ago.
