Hi Karen, thanks for accepting our invitation. With regard to the Ce and Eu anomalies, clear portions have higher Ce anomlies than cloudy portions, but Eu anomalies do not exist. If this reflects fO2, what kind of range could it be? How would this relate to diamond formation? Thanks, Jingao

Thank You for Your talk Karen! Did You try to estimate the amount of both the CH4-bearing fluid inclusions and graphite in the cloudy zones, to validate/reject their effect on dilution of the trace elements? Thanks!

Are there studies on REE partition coefficients between COH fluids/melts and silicate minerals (e.g. gt and cpx)? Are these REE in the diamond being sourced from a subduction or mantle (lherzolitic) component? And can this give insight into the source of these COH fluid/melt that formed the diamonds?
