Abstract
AN analysis of the lanthanon (rare earth) fraction from davidite, a uranium–iron–titanium oxide complex from the Radium Hill area of South Australia, has revealed an unusual variation in the abundance of the lanthanons. The accompanying table compares (a) the percentage abundance found for davidite, with (b) that given by Goldschmidt and Thomassen1 for some uranium–titanium–niobium–tantalum complex oxide minerals, and (c) xenotime. Also included in the table are Goldschmidt's values (d) for the average terrestrial abundance of the lanthanons, this abundance differing from that found for monazite mainly in exhibiting a slightly smaller proportion of the lighter (cerium group) lanthanons.
