英文摘要	We present in this study an improved chemical separation method for Lu-Hf and Sm-Nd from a single rock dissolution. Rock samples were digested using Li2B4O7 fusion in order to complete decomposition of refractory accessory minerals. Separation of Sm-Nd-Lu-Hf was carried out using a combination of either Dowex AG50W-X8 and HDEHP chromatographic columns or Eichrom RE and HDEHP column:. Analytical reproducibilities of Nd and Hf sotopic ratios were demonstrated for USGS rock standards BHVO-2 and GSP-2 and GSJ rock standard JB-1 and reproducibilities of Lu/Hf and Sm/Nd were demonstrated for BHVO-2, JB-1 and JB-3. Our results show overall good agreement with the recommended values. In addition, we conducted duplicated analyses on national rock standards GBW07109, GBW07110 and GBW07113, and reported for the first time their Nd and Hf isotopic ratios.
