✦ Synopsis

The problem of fast heavy nuclei track registration and track stability in natural and artificial crystals is generally discussed in the frame of four -zone model of tracks, first suggested in 1972. The results on sensitivity calibrations of the crystals, the efficiency of particle registration, the sources of background, the thermal stability of latent tracks, the uranium content in crystals are reviewed. The data on tracks age and fossil galactic cosmic ray nuclei tracks in crystals provide a very important information about the nucleosynthesis processes in our Galaxy, about the history of the Earth and about the charge and energy spectra of cosmic ray nuclei with Z > 26 averaged over time intervals up to 200 M.Y.

The dependence of vol,,me etchable track length (VETL) on threshold annealing procedure and track orientation in crystal lattice suppose to be very important for fossil and fresh track studies.
