S>Methods are described for the determination of major and minor chemical constituents in fine-grained sedimentary rocks. They include wet- chemical methods, radiometric and flame-photometric methods, absorption and emission spectroscopic methods, and fluorescent x-ray procedures. The major elements are determined by a rapid semi-micromethod on two samples, one of which is decomposed by fusion with sodium carbonate: the other sample is decomposed by digestion with sulfuric and hydrofiuoric acids. Trace elements are determined by spectrochemical procedures using internal standards. Carbon, sulfur, and the carbon present in carbonate minerals are determined by conventional methods. A fiuorescent x-ray spectroscopic method for iron and molybdenum is described. (auth)
