| 概要≠ | Obsidian hydration dating (OHD) is a chronometric method that determines the age of obsidian artifacts by measuring the thickness of a hydration layer formed on their exposed surfaces. Developed by Irving Friedman and Robert Smith in 1960, it is based on the principle that fresh obsidian surfaces absorb water from the surrounding environment at a measurable rate. The method is particularly valuable in archaeology for dating volcanic glass tools and other obsidian objects, especially in regions where obsidian was commonly used for cutting and scraping implements. | 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. |
