以红外光为激发光源
测得拉长石、歪长石、叶钠长石、钠长石和微斜长石的α -饱和剂量分别为 4 5 0 0、140 0 0、6 80 0、2 4 0 0 0、30 0 0 0Gy
β -饱和剂量分别为 2 30、4 0 0、10 0、4 0、2 2 0Gy。如果用这些矿物进行红外光释光测年
其测年上限分别为 16万年、2 8万年、7万年、2— 3万年和 15万年左右
The optical luminescence of mineral is its luminescence character. This character is related to the frequency and intensity of stimulating source. It is important to understand these relationships for OSL dating. Saturation doses of 5 feldspars
Labradorite
Anorthoclase
Cleavelandite
Albite and Microcline
have been determined with infrared stimulated luminescence.
