| Abstract;Radiation defects in some feldspars, including microcline and albite, were investigated from aspects of correlation between thermoluminescence phenomena and ESR-signals. Al-O center and H-radical were found in any feldspars when the samples were irradiated and measured at 77K. After warming to room temperature, Al-O center was converted into Al-O-Al center. Thecomplete disappearance of H radical after warming was verified to be operated to decrease of Al-O-Al center, which was identified to a main center of blue TL possessing 180.DEG.C. peak. The thermal annealing treatment of microcline beyond 700.DEG.C. brought on appearance of two new hydrogen signals, which are observable in room temperature. (author abst.) |
