Deep Subduction in Earth history: Seeking for traces in the sedimentary record

Abstract

I am extraordinarily grateful to my main supervisors Prof. Dr. Hilmar von Eynatten and Prof. Dr. Guido Meinhold. After finishing my Master's thesis, I received continuous and endless support for translating my research ideas into reality and for developing a specially tailored PhD project. Without the mentoring, guidance, patience, motivation, and professional knowledge of Hilmar and Guido, none of the lines included in this thesis would have been written down. As well as for the time we spend together in the field and the many fruitful discussions we had, I am additionally thankful for support to facilitate my future career aspirations.Many thanks to Dr. N. Keno Lünsdorf for supervising the Raman spectroscopy part of this project. Over the years, I was fortunate enough to rub off a small proportion of the in-depth understanding Keno has regarding technical details and how to tune experimental parameters for the optimal outcome. I am also grateful for several scripts Keno wrote and provided, which allowed to organize my analytical work much more efficiently.Besides my supervisors, I thank all professional colleagues for collaborations on various subprojects during my PhD studies. This includes Dr.
