| Résumé≠ | Optically stimulated luminescence (OSL) dating is a chronometric method that determines the age of sedimentary materials by measuring light-induced electron release from mineral grains. Developed by David Huntley and colleagues in the 1980s, it measures the time elapsed since sediment was last exposed to sunlight. This technique is widely used in archaeology, geology, and paleoenvironmental studies to date deposits ranging from a few decades to several hundred thousand years old. | Electron spin resonance (ESR) dating is a chronometric method that determines the age of bones, teeth, mollusk shells, and sediments by measuring accumulated radiation-induced unpaired electrons. Developed by Michael Aitken in the 1980s, ESR detects free radicals trapped in mineral crystal structures. Unlike luminescence techniques that require heating or light exposure, ESR directly measures paramagnetic defects, making it particularly valuable for dating dental and skeletal remains that are inaccessible to other methods. |
