Neutron activation analysis of altered oceanic tholeiite: Variation of lanthanide concentrations with degree of alteration
Journal of Radioanalytical and Nuclear Chemistry(2005)
摘要
Lanthanides in altered oceanic tholeiite were determined by means of instrumental neutron activation analysis. Potassium content was employed as a measure of degree of alteration. Lanthanide concentrations in moderately altered parts of tholeiite (K2O content below 1%) were identical with those in'unaltered parts while light lanthanide concentrations in more altered parts (K2O content above 1%) increased with degree of alteration.
