Ll. Kashkarov et al., TRACK ANNEALING CHARACTERISTICS FOR NATURAL GLASSES OF DIFFERENT CHEMICAL-COMPOSITION - A PROBLEM OF ZHAMANSHIN IMPACT CRATER DATING, Radiation measurements, 25(1-4), 1995, pp. 531-532
Results of artificial annealing of the basic and acid Zhamanshin glass
es are presented, The basic glasses have lower thermal stability as co
mpared to the acid glasses, but this difference is not sufficient to e
xplain the track age discrepancy between these glass objects.
