Extract

X-ray spectrometry has been used successfully for major and trace element analysis of geological samples (e.g. reference 1). Its advantage is providing accurate and precise results in a rapid manner: a key factor in selecting analytical methods for mineralogical studies involving large numbers of samples. All elements with atomic numbers greater than 9 (fluorine), except noble gases, can be determined with sensitivities ranging down to ppm levels.

The analytical method described in this report is for the determination of the major elements (i.e. Na, Mg, Al, Si, P, K, Ca, Ti, Mn and Fe) in geological samples. Commercially available automated fusion devices are used for sample preparation.
