	1	Determination of Hf–Sr–Nd isotopic ratios by MC-ICP-MS using rapid acid digestion after flux-free fusion in geological materials显示文摘In this study, we established a rapid acid digestion for determining Hf–Sr–Nd isotopic ratios of geological samples by using MC-ICP-MS. Conditions of 1600 °C for 1 min and 1400 °C for 1 min were adopted for fusing intrusive rocks and extrusive rocks, respectively. The rapid acid digestion technique is superior in digestion time compared with high-pressure PTFE bomb method. The procedural blanks of the method were also lower than that flux fusion. Replicate analyses of international certified reference materials(CRMs) indicate that isotopic ratios of ^(176)Hf/^(177)Hf,^(87)Sr/^(86)Sr and^(143)Nd/^(144)Nd agree well with previously published data. The external reproducibility(2 SD, n = 5) of ten CRMs are ±0.000030 for87 Sr/86 Sr,±0.000030 for ^(143)Nd/^(144)Nd, and ±0.000018 for ^(176)Hf/^(177)Hf.
