Pulsing the stimulation allows the separation of quartz and feldspar luminescence signals for dating of mixed mineral samples
Sometimes mineral separation in sediment or solid samples is not possible (polymineral samples), especially in cases of intergrowth of minerals. Pulsing (i.e. short light stimulation) the stimulation employs the different decay times of luminescence signals from different minerals in order to detect the luminescence signal predominately from a single mineral.
Separate luminescence signals from different minerals
Avoid tedious sample preparation
