| Abstract: | Eighteen Chinese geologic reference samples (stream sediments GSD 9–12, soils GSS 1–8, and rocks GSR 1–6) were analyzed by wavelength-dispersive X-ray fluorescence spectrometry (XRFS) for major elements Si, Ti, Al, Fe, Mn, Mg, Ca, Na, K, and P, and by energy-dispersive XRFS for trace elements Ba, Ce, Cr, Cu, La, Nb, Ni, Rb, Sr, Y, Zn, and Zr. Major element analysis followed gravimetric determination of loss on ignition, and samples were prepared by fusion with Li2B4O7. A loose-powder sample preparation was used for trace element analysis. The results reported in this study are, generally, in good agreement with concentrations compiled by X. Xie of the Geochemical Standard Reference Group and the Institute of Geophysical and Geochemical Exploration (People's Republic of China). |
