A method has been developed to identify heavy ions from their etchable tracks in feldspars, by measuring the track etching rates and the residual ranges of individual tracks. It was found that a resolution of one charge unit can be achieved if irregularly etched tracks are eliminated from evaluation. To study the long term average of the galactic cosmic ray composition, feldspar crystals of lunar and meteorite samples were etched according to this method.
