Current Project, start May 2021

LABEX funded postdoc – The fate of Ti-bearing minerals: experimental and natural tales of the oceanic crust from genesis to subduction, exhumation and erosion

Aim: Development of new Ramanbarometry tool using Ti-phases and their inclusions and combine these with trace-element based discrimination tools to probe the sedimentary rock record. Continuation of the experimental constraints from the previous project.

Previous Project, Dec. 2019 – April 2021

UCA Fellowship – The fate of Ti-bearing minerals: experimental and natural tales from the oceanic crust during the Wilson cycle

Aim: To combine what we can learn from mineral phase stability from experimental petrology with the development of new trace element chemistry proxies to fingerprint Ti-bearing mineral growth in the P-T space.

Outputs: We are currently working on a publication and two abstracts regarding a substantial part of this research project were presented at vGoldschmidt 2021.
