Abstract
Methods are described for the rapid analysis of strontium and rubidium in micas and alkali feldspars by emission spectrography. The elements are determined in a common matrix, excess barium carbonate acting as buffer and internal standard. The techniques are applicable to the analysis of 5–500 p.p.m. strontium in the minerals, with relative deviations of ±5–8%. Semiquantitative results are obtained for 100–1500 p.p.m. rubidium in the same materials. These methods have also been successfully applied to the analysis of strontium and rubidium in certain whole rocks. Results obtained with the standard granite G-1 and standard diabase W-1 show satisfactory agreement with the recommended values.
