Minerals found in sediments are responsive to light. Electrons present in the sediment grains leave the floor state when subjected to light, called recombination.
To look for the chronilogical age of sediment, experts reveal grains up to an understood amount of light and compare these grains aided by the sediment that is unknown. This method can help figure out the chronilogical age of unheated sediments lower than 500,000 yrs . old. a drawback to the strategy is to get accurate outcomes, the sediment to be tested may not be exposed to light (which will reset the “clock”), making sampling difficult.
