| Samenvatting≠ | 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. | 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. |
