抄録: A technique for analyzing concentrations of Mg, Ca and Sr in small aragonite samples is developed. Samples are rinced with hot alkaline peroxide and decomposed by HNO_3. The trace element concentrations are analyzed by graphite furnace-atomic absorption spectrometry (GF-AAS) and determined using calibration line. The detection limits for this method are <0.27pg for Mg, <1.1pg for Sr and <75pg for Ca. This study adopted matrixmatching model to correct errors of measurement values. As a result, analytical errors are reduced to less than 5%. We could obtain reliable trace element ratios of aragonite samples even if the sample amounts are too small (<100μg). This technique enables us to make trace element analysis using small samples and it is useful for high-resolution paleoenvironmental reconstruction along the growth of coral and molluscan shells.
