Rapid separation of Lu-Hf and Sm-Nd from a single rock dissolution and precise measurement of Hf-Nd isotopic ratios for national rock standards
同一岩石试样的Lu-Hf和Sm-Nd快速分离及国家岩石标准物质的Hf-Nd同位素比值精确测定

Abstract 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 Li2 B4 O7 fusion in order to complete decomposition of refractory accessory minerals. Separation
