Precise and accurate Lu-Hf isotope analysis of columbite-group minerals by MC-ICP-MS

Due to their relatively high Hf contents ( i.e. , several hundreds to thousands of ppm), columbite-group minerals (CGMs) are suitable for Lu-Hf isotope analysis, which can provide new insights into the source of such minerals in combination with the U-Pb age of rare-metal deposits. However, few stud...
