| Abstract: | Methods of digestion of samples by acidic dissolution and in fused sodium peroxide were modified in conformity with the chemical composition of basalts, periotites and stone meteorites as well as the method of REE pre-concentration by the lanthanum fluoride cycle. The enriching methods were used for the neutron-activation determination of the individual rare-earth elements in rocks and meteorites with a sensitivity up to 10−8%. |
