Experimental results for most rare‐earth elements, yttrium and thorium in several international geological reference samples are presented and compared with other published values, where available. The analytical method used to obtain these results involved a preliminary concentration of the rare‐earths On milligram quantities of iron as carrier for atomic‐absorption, flame‐emission and spectrophotometric determinations, or on milligram quantities of Fe 2 O 3 , Al 2 O 3 and SiO 2 as carriers for optical‐emission spectrometric determination.
