Abstract

Elucidating the material cycle in the terrestrial mantle is one of the major goals of the field of geoscience. Radiogenic isotopic ratios such as strontium (Sr), neodymium (Nd), and lead (Pb) have been used to track recycled components in the mantle. This study shows that the non-traditional lithium (Li) isotopic tracer has a great potential to provide a major breakthrough in the investigation of the material cycle in the terrestrial mantle.
