- Abstract:
- We propose to synthesize deep-mantle phases of more complex minor and trace-element chemistry and characterize their transformation behaviour at high P-T. We will investigate the effects of Fe, Al, and H/D substitution on the transformation of spinelloids and spinels to perovskite, and especially the role of proton chemistry in the transition zone. The experimental methods will comprise the multi-anvil apparatus and the diamond-anvil cell coupled with micro-Raman spectroscopy, and a new nano-SIMS facility. To bridge the gap between temperatures we can achieve by laser-heating and room temperature, we will develop micro heaters for our DAC to generate temperatures of the upper mantle and subduction zones at high-pressure.
