Title: Experimental Investigations into the Fate of Subducted Carbonates andOrigins of Super-Deep Diamonds

Time: 13:30 - 14:30 PM, June 6, 2017

Place: Conference Room 603 Tang AoQing bulding, HPSTAR (Changchun)

Host: Dr. Jiuhua Chen

Abstract

Superdeep diamonds are important for deep Earth research because they open windows into the sublithospheric regions of the mantle. Mantle-slab interaction has been proposed as a mechanism to produce diamonds at depths greater than 250 km. While the reaction has been verified by experimental studies at pressures below 7 GPa, it is not known if it can occur at relatively low temperature and high pressure conditions corresponding to the source depths of the majority of superdeep diamonds. In this talk I will show new data on the reaction kinetics of metal-carbonate reaction from diamond-anvil-cell experiments and discuss the implications for their origin and distribution.

Biography of the Speaker

Prof. Jie Li (李洁) is a well established mineral physicist in US. She was trained as a large volume press experimentalist during her PhD study at Harvard University and quickly extended her expertise in diamond anvil cell research as well.  She is widely recognized for her work on composition of Earth’s core and deep carbon cycling.
