Abstract

The use of an automated, software‐controlled X‐ray fluorescence spectrometer (Phillips AXS System)for analysis of geologic materials gives rapid, precise results. Fluorescence intensities are corrected for background and peak overlap and for mass absorption, and ratioed to a standard rock analyzed at frequent intervals. Major element determinations show precision and accuracy in the 0.5–3% range and are based on calibration with a wide variety of international reference rocks. Determinations for major elements are done on specially fused rock powders. Precision and accuracy for trace elements are generally in the 1–5% range. Calibration is also by use of reference rocks but the determinations are done directly on pressed rock powders.
