Previous studies suggested that the 45 m diameter structure was produced by a fall in recent times (less than 5000 years ago) of an iron meteorite impactor into quartz-arenites and siltstones belonging to the Lower …Absolute dating methods mainly include radiocarbon dating, dendrochronology and thermoluminescence. Relative Dating. Stratigraphy Inspired by geology, stratigraphy uses the principle of the superposition of strata which suggests that, in a succession of undisturbed SOILS, the upper horizons are newer than the lower ones. …In thermoluminescence, the electron was originally promoted by electromagnetic radiation or some other energy source and then trapped in the excited state (Wintle and Huntley 1982; Forman 1989). The trapping centers are generally defect sites caused by radioactive or stacking faults, but they can also be caused by ion substitution.Luminescence dating is based on the perception in solid state physics that energy from the absorption of ionizing radiation can be stored in the crystal lattice of insulators as radiation damage. Thermal or optical stimulation of dosed mineral grains results in release of radiation-induced luminescence.

The technique was first developed in the 1960s, with the aim of dating archeological ceramics to determine the time elapsed since firing (using thermoluminescence, TL, dating).In the context of using luminescence for dating, the luminescence signal arises from the release of energy stored from prior exposure to ionizing radiation such as alpha, beta, or gamma radiation. Thus, luminescence provides a mechanism for measuring the amount of ionizing radiation a sample has been exposed to. Thermoluminescence …Thermoluminescence (TL) dating has been used to determine the age of the meteorite impact crater at Gebel Kamil (Egyptian Sahara).
