| Résumé≠ | Uranium-thorium (U-Th) dating is a chronometric method that determines the age of carbonates, shells, bones, and coral by measuring the ratio of uranium isotopes to thorium-230. First applied by Harmon Craig in the 1950s, it exploits the natural radioactive decay chain of uranium. U-Th dating is particularly valuable for dating materials from 500 to 500,000 years old, filling a crucial chronological gap between radiocarbon and potassium-argon dating. | Thermoluminescence (TL) dating is a chronometric technique that determines the age of pottery, ceramics, and sediments by measuring light emitted when heated to high temperatures. Pioneered by Michael Aitken in the 1960s, it quantifies the accumulated radiation dose stored in mineral crystal lattices. The method revolutionized archaeological dating by enabling scientists to date ceramic vessels and fired clay objects directly, providing absolute chronologies for human occupation sites worldwide. |
