Annealing characteristics of spontaneous (fossil) and induced (recent) fission tracks in sphene were measured in a temperature range of 873 to 768 K. Results include the reduction of number density, maximum track length (horizontal projection), and average track length (horizontal projection), as a function of annealing time (up to 1.5*10/sup 7/s (175 days)). Using the track dimension method, a corrected fission track age for sphene t(l/sub min/) was derived. The annealing characteristics are interpreted by means of a new annealing model, yielding information about the elementary processes governing the annealing mechanism for the etchable zone of fission tracks. 45 refs.
