Luminescence dating including thermoluminescence and optically stimulated luminescence is a type of dating methodology that measures the amount of light emitted from energy stored in certain rock types and derived soils to obtain an absolute date for a specific event that occurred in the past. The method is a direct dating technique , meaning that the amount of energy emitted is a direct result of the event being measured. Better still, unlike radiocarbon dating , the effect luminescence dating measures increases with time. As a result, there is no upper date limit set by the sensitivity of the method itself, although other factors may limit the method's feasibility. To put it simply, certain minerals quartz, feldspar, and calcite , store energy from the sun at a known rate.

Luminescence dating refers to a group of methods of determining how long ago mineral grains were last exposed to sunlight or sufficient heating. It is useful to geologists and archaeologists who want to know when such an event occurred. It uses various methods to stimulate and measure luminescence. It includes techniques such as optically stimulated luminescence (OSL), infrared stimulated. What is Luminescence Dating? Luminescence dating is a form of geochronology that measures the energy of photons being released. In natural settings, ionizing radiation (U, Th, Rb, & K) is absorbed and stored by sediments in the crystal lattice. This stored radiation dose can be evicted with stimulation and released as luminescence. phenomena - thermally stimulated luminescence and optically stimulated luminescence. The most com-monly used luminescence stimulation and detection techniques are reviewed and information is given on recent developments in instrument design and on the state of the art in luminescence measurements and analysis. # Elsevier Science Ltd.

Luminescence Dating. OSL dating yielded ages between 93±6ka and 64±5 Ka. The resulting sedimentation rates are larger than in the other localities of Tafi del Valle, probably due to the different topographic settings within the inter mountain basin. The instrument consists of a heat or light source for stimulation and a photon detector. Luminescence dating instrument - Men looking for a man - Women looking for a woman. Find a man in my area!
