Abstract
Laboratory irradiated rock and mineral samples were studied for their luminescence properties. The effect of alteration of feldspars on luminescence intensity was determined by the autoradiographic method for porphyritic granodiorite planar rock samples and with the TL reader for crushed minerals. Feldspars and quartz exhibited more intensive luminescence than mafic minerals, and luminescence of fresh K feldspar was the most intense. Potassium concentration did not have any effect on luminescence intensity for K feldspars but the intensity was highly dependent on the alteration degree of the mineral. Decrease in luminescence was found without a change in the element composition of the mineral and alteration was due to sericitization of K feldspar.
