Dear list members, we are thrilled to announce an exciting opportunity for a *Postdoctoral Researcher* to join our experimental petrology team at the Ruhr-University Bochum, Germany. This position offers a unique opportunity to contribute to cutting-edge research on the *formation of submarine basalts*. The full description of the position is provided below. If you are interested please feel free to contact me directly at *thilo.bissbort@ruhr-uni-bochum.de*. Please forward this announcement to anyone who might be interested. *2-year (100%) Postdoctoral Research Position, Experimental Petrology and Geochemistry, Ruhr-University Bochum, Germany* *_Position summary_* The Experimental Petrology and Geochemistry workgroup at the Ruhr-University of Bochum is inviting applications (m/f/x) for a full-time, 2-year, DFG-funded Postdoctoral research position. This position is part of the project “Formation of submarine basalts”, which is led by Thilo Bissbort and funded as part of the SPP 1006 ICDP program. The project aims to improve our understanding of how submarine basalts form by studying samples from the HSDP2 drilling project in Hawaii. Employing state-of-the-art analytical methods that include techniques like fast differential scanning calorimetry and TEM, we will specifically shed light on two main aspects: (1)    Thermal history of submarine basalts from small to large scale. (2)    Crystallization dynamics in submarine basalts. The study will involve the detailed characterization of pristine HSDP2 samples, as well as samples that have undergone thermal analysis, using a variety of techniques. Glass transition temperatures will be measured by differential scanning calorimetry. Cooling rate gradients on small and large scales will be reconstructed based on enthalpy-relaxation-geospeedometry results. These will then be compared to commonly applied heat conduction models. Systematic, controlled cooling experiments, combined with detailed chemical and spectroscopic analysis, will be employed to investigate the impact of cooling rates on phenomena like nanoscale phase separation and the formation of nanolites. The results of this study will be interpreted in terms of the dynamics of submarine basalt formation including thermal history, the formation of phases linked to this process, and the resulting rheology. The project is taking place at the Ruhr-University Bochum in Germany and in close cooperation with the Department for Earth and Environmental Studies at the Ludwig-Maximilians University in Munich, Germany. The Department of Geosciences at RUB boasts a comprehensive array of analytical and experimental facilities.
