Tóm tắt	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.	Archaeomagnetic dating uses changes in Earth's magnetic field intensity and direction recorded in fired clay artifacts to determine age. Pioneered by Robert Coe in the 1960s, the method measures the magnetization of pottery and baked clay features, comparing measurements to a master curve of geomagnetic variation through time. Archaeomagnetic dating is most effective for materials dated to the last 10,000 years and is particularly powerful in arid regions where clay artifacts are well-preserved.
