Silicate Analysis as Viewed by Geological Surveysost difficult and exacting forms of analysis, often requiring many hours for one determination. As analysts in such laboratories are confronted with a bewildering variety of samples, they must be familiar with many chemical and physical methods of analysis. A particular philosophy and special types

Silicate Analysis—a Glance Backward and a Look Forwardoldschmidt’s geochemical investigations in the 1930’s established the utility of spectrography for quantitatively determining trace elements in rocks. This technique remains the best instrumental method for yielding the maximum qualitative and quantitative information with the minimum effort. This s

Glass Reference Standards for Trace Element Analysis of Geologic Materialsn 46 added elements at uniform concentration levels aimed at 500, 50, 5, and 0.5 ppm, respectively. The blank represents the matrix composition approximating an average igneous rock. Preliminary evaluation spectrochemically of the trace element content and homogeneity of these glasses has demonstrated their usefulness as reference standards.
