Methods are described for the determination of major and minor chemical constituents in fine-grained sedimentary rocks. They include wet-chemical, radiometric and flame-photometric methods, as well as absorption and emission spectroscopic and fluorescent x-ray procedures. The major elements are determined by a rapid semimicromethod on two samples, one of which is decomposed by fusion with sodium carbonate, the other by digestion with sulfuric and hydrofluoric 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 fluorescent x-ray spectroscopic method for iron and molybdenum is described. (auth)
