摘要: 熔融片法制样，用X射线荧光光谱法测定页岩样品中硅、铝、铁、钙、钾、镁、钠7个主量元素，以页岩、岩石、水系沉积物、土壤国家一级标准物质作为校准样品，使用理论α系数和经验系数相结合的方法校正基体效应。方法精密度（RSD，n=12）≤1.50%。分析结果与化学法进行对照基本一致。

Abstract: A method for the determination of major elements including Si, Al, Fe, Ca, K, Mg and Na in shale samples by X-ray fluorescence spectrometry with fused glass disc sample preparation was reported in this paper. The shale, rock, sediment and soil National Standard Reference samples were used as the calibration standards. The matrix effect was corrected with theoretical alpha coefficient and empirical coefficient methods. The precision of the method is ≤1.50%RSD (n=12). The method has been applied to the determination of these major elements in shale samples and the results are in agreement with those by chemical methods.
