摘要

Twelve samples from three Antarctic lake cores in the Schirmacher Oasis (East Antarctica) were selected for dating by a method using infra-red stimulated luminescence (IRSL). A spectral study of the luminescence signal from coarse grain plagioclase feldspars by a high sensitivity TL/OSL spectrometer using a CCD-camera showed four wavelength maxima, and the comparison of the equivalent doses (D_E) measured at these wavelength, namely 280, 330, 410 and 560 nm, yielded different values. The ages were calculated using D_E obtained at 560 nm.
