  Topic: Tracing the formation and differentiation of the Earth by using non-traditional stable isotopes

  Speaker: Prof. Fang-Zhen TENG (Univ. of Washington, Seattle)

  Time: 10:00 AM, July 24th (Wednesday)


  Conference Room 701 of Main Building

  Brief Introduction of the Speaker:

  Fang-Zhen Teng is a professor in the Department of Earth and Space Sciences at the University of Washington, Seattle and a life fellow of the Mineralogical Society of America. His research interests focuses on the composition and evolution of the continental crust, crust-mantle interactions and the origin and evolution of the solar system through analyses of non-traditional stable isotopes (lithium, boron, magnesium, potassium, iron, copper, zinc etc.). To date, he has published >100 peer-reviewed papers on Science, PNAS, Nature Communications, GCA, EPSL, Geology, etc. with an H-Index = 41 and total citation of >5000.

  Talk Abstract:

  The Earth has grown from a chaotically mixed small particles and gases to the present highly differentiated layered structure over the past 4.567 billion years. This differentiation has led to the formation of the atmosphere, hydrosphere, biosphere, crust, mantle and core. How and when these different layers formed and evolved are still not well-constrained. This talk will focus on using non-traditional stable isotopes to trace some important events and processes in the formation and differentiation of the Earth, such as the Moon-forming giant impact, crust-mantle interactions, origins and evolution of life, and the rising oxygen level in the atmosphere.
