In order to investigate the volatilities of major and minor lithophile elements, evaporation experiments by electron bombardment were carried out employing basaltic rock powder. The elements studied included Al, Fe, Ca, Mg, Mn, Na, K, Rb, Ba and REE. The source crucible was heated to about 2300 °K, and the vaporized material was collected at different distances from the source. The enrichment factors of studied elements in the material collected on the condensation plate were calculated relative to the starting material. Patterns of REE removed during flights between varying distances were also evaluated.
