The initial rate of loss of luminescence due to infrared stimulation of K-feldspars

摘要

Repeated stimulation by infrared of a feldspar sample causes a reduction in the luminescence signal. The initial rate of loss of luminescence due to infrared stimulation is investigated for a microcline and an orthoclase with preheating at 150 degreesC, 180 degreesC and 220 degreesC for times ranging from 20 to 2400 s.
