The development of Earth and planetary science cognition often correlates with breakthroughs in frontier analysis and observation techniques. I am primarily engaged in research related to geochemistry and cosmochemistry, focusing on scientific questions regarding the formation and geological evolution of Earth and other terrestrial planets. I develop ultra-high precision or high spatial resolution isotopic analysis methods, particularly utilizing metal isotopic methods to bring crucial constraints. Some representative contributions to date include:
1. Revealing that early martian crust was intensely oxidised during impact reworking and providing a viable heat source to sustain surface liquid water on early Mars despite the faint young Sun (Deng et al., 2020, Science Advances; Pan et al., 2023, GRL).
2. Discovering that mass exchange between the upper and lower mantle was limited for most of Earth's geologic history, and modern-style plate tectonics only represents a recent feature of Earth (Deng et al., 2023, Nature).
3. Revealing a ubiquitous contribution of sedimentary silica in the magma sources of Archean granitoids and pinpointing the onset of supracrustal recycling on Earth (Deng et al., 2019, Nature Geoscience).
4. Unraveling the complication of Ti isotopic fractionation during magma differentiation and reconciling the debate on compositional evolution of continental crust in deep time (Deng et al., 2018, GPL; Deng et al., 2019, PNAS).
5. Developing novel in situ or solution-based metal isotope techniques for meteorites and bringing constraints on the early Solar System processes, e.g., gas condensation (Martins et al., 2020, EPSL), chondrule formation (Deng et al., 2021, GCA), terrestrial planet accretion (Onyett et al., 2023, Nature; Moynier et al., 2020, EPSL).
6. Characterising and providing the suited international reference materials (i.e., rutile, ilmenite, titanite and perovskite) for in situ Ti isotopic measurement via LA-MC-ICP-MS (Liu et al., 2023, SAPB; Liu et al., 2023, GGR).
My current focus is on integrating laboratory work and fundamental theory to conduct in-depth research on Earth and meteorite samples, and samples returned from planetary exploration missions, providing constraints for planetary-scale scientific questions. This involves: 1) nebular collapse and protoplanetary disk evolution; 2) terrestrial planet accretion and differentiation; 3) geological evolution and habitability evolution of terrestrial planets. I also encourage and support students, postdocs, and collaborators to develop and explore new research topics. Students interested in related research topics and considering undergraduate, master's, doctoral, or postdoctoral research are welcome to contact me by email (zhengbindeng@ustc.edu.cn).
