Marine clay maturation induces systematic silicon isotope decrease in authigenic clays and pore fluids Open
Marine silicate alteration exerts a major influence on marine carbon and cation cycles, but has proven difficult to quantify. In this context, silicon isotopes of marine pore fluids became an important tracer. However, poorly constrained s…

Expression of the Palaeocene-Eocene Thermal Maximum in shallow-water carbonates of central eastern Tethys (Lower Indus Basin, Pakistan) Open
The Palaeocene-Eocene Thermal Maximum (PETM) was the most prominent climatic perturbation of the Cenozoic, characterized by rapid warming and ocean acidification. Major biotic impacts include a substantial deep-sea extinction event and a s…
