Abstract

The anomalous fading of trapped charge in martian analogue materials such as basalt and andesite rock samples is measured. Optically stimulated luminescence (OSL) signals show rapid fading (of between 4% and 27% per decade). Fading rates obtained using high temperature thermoluminescence signals are smaller. The importance of knowing whether a standard fading correction method is applicable to samples of unknown age is illustrated by application to an 'infinitely old' known-age basalt, for which both the uncorrected and fading-corrected natural signals lie within the approximately linear region of the growth curve.
