Abstract
This work is intended to explore a fast and effective approach to the determination of various trace elements in geological samples through improvement and simplification of the method developed by Reynolds (1963, 1967). Absorption correction was made for the Fe content to eliminate the effect caused by inconsistency in mass absorption coefficients among the samples. A computer-aid regression analysis was performed on a number of standards of various compositions, which resulted in a set of calibration equations for directly converting X-ray intensities to concentrations. An analytical error of 10–30% was involved in the analyses of most elements.
