Hans-Martin Krolzig a highly sensitive fluorometric method has been developed to determine the boron content in iron and stone meteorites. The detection limit lies at the ppb-level. For the lithium determination we use a thermal-neutron activation technique..In Canon Diablo and in Toluca iron we found 0.02 and 0.03 pp

Hans-Martin Krolzighen differences in volatility could also be considered the main type of cause of this fractionation. The enrichment of Fe, however, would have to have occurred at a much earlier stage than the fractionation indicated by the composition of ordinary chondrites as compared to Type I carbonaceous chondr

Hans-Martin Krolzigeorite. The variations have been examined very carefully and no instrumental effect has been found which could explain these anomalies. If a neutron irradiation were to be retained as a possible explanation, the flux required would be compatible with the limit set by the Boron results mentioned abov
