W-182 anomalies in mantle: a brief review TEXT SIZE: A A A

With significant advances in mass spectrometry for isotope analysis in the last decade, e.g., negative thermal ionization mass spectrometry and multi-collector inductively coupled plasma mass spectrometry, high-precision (ppm-level) measurements of tungsten (W) isotopes have been widely used for early earth differentiation processes, such as metal-silicate segregation, melting and crystallization processes during the magma ocean, and putative core-mantle exchange and dynamics. Here, we give a brief review of works on W-182 anomalies in terrestrial samples, including methods, results, explanations, implications, and prospects. The review will be presented by including the following parts: the introduction of W isotopes and the short-lived radioactive Hf-182-W-182 system; data notations and W isotope measurement methods; W-182 anomalies observed in terrestrial samples; a summary of models developed for interpreting origins of positive and negative W-182 anomalies; future prospects.
