摘要：

Thermoluminescence (TL) spectra from separated fractions of a multi-component sand have been recorded over the temperature range from 60 to 300 K. Mineral fractions were selected by a combination of density separation and acid etching. The feldspar fraction produced an intense red emission together with weaker blue/green components. By contrast the quartz and heavy mineral fractions showed primarily the blue/green emission. In all cases there were blue/green glow peaks near 90 and 130 K, with additional features in this wavelength range for the "light" feldspar fraction. On the basis of peak temperature, or spectral analysis of the conventionally recorded blue/green emission, it is not possible to distinguish the minerals responsible for the low temperature glow peaks from this sand. However, the lighter density feldspar fraction had an intense red emission relative to that in the blue or green region.
