I’m mainly interested in the geochemical study of metal stable isotopes (Cu, Zn, Mg, Cd, Cr, etc.), focusing on the early Earth’s environment and life evolution, the Earth’s deep carbon cycle and its climate response, and the use of copper and zinc isotopes in mineral deposit studies.
In recent years, my research group has systematically studied the behaviors of Cu-Zn isotopes in high temperature magma process, continental weathering, adsorption, and oceanic alteration, and provided new baseline data for Cu-Zn isotope composition of the silicate Earth (BSE).
We applied Zn isotopes to the study of bio-extinction mechanisms, providing new Zn isotope evidence for the large-scale volcanism immediately before the end of the Permian bio-extinction and the rapid recovery of marine primary productivity after mass extinction. We also have provided independent Zn isotope evidence for sea level decline during the period of the F-F extinction.
We also applied Zn isotopes to the study of Earth’s deep carbon cycle for the first time and found a large-scale Zn isotope anomaly of Cenozoic alkaline basalts in eastern China. Together with Mg isotope data, we provided key evidence for the existence of large-scale recycled carbonate (magnesite) in the upper mantle beneath eastern China. We also proposed that the compositional transition of alkaline basalts in eastern China is achieved via the interaction of carbonated melt with the lithosphere.
In addition, we developed the application of Cu isotopes to high-temperature magmatic deposits, and provided key evidence for initial Cu enrichment in the source area of giant porphyry deposits. I studied the genetic difference between the ore-bearing and ore-barren adakite rocks in eastern China, and proposed that the large-scale Cu-Au mineralization in the lower Yangtze River belt is related to the subduction and melting of the oceanic slabs.
