 note = {application/pdf, A technique for analyzing trace amounts of Ba. Be, Li, Pb, Rb, Sr, K and Ti in rock samples is described. In this technique, rock or mineral samples are decomposed by HF-H_2SO_4 or HF-HNO_3 and the trace element concentrations are determined by graphite furnace-atomic absorption spectrometry (GF-AAS) using standard addition. The detection limits for this method are < 6 pg for Ba, Be, Li, Pb, Rb and Sr and < 40 pg for K and Ti. The trace element concentrations determined for eight GSJ rock reference samples showed good agreement with the recommended values, and the analytical errors were less than 5%. This technique enables to obtain reliable trace element compositions of rock and mineral samples even if the sample sizes are very small (< 10 mg).},
