Grain-scale stable isotope disequilibrium during fluid-rock interaction. 2: an example from the penninic-austroalpine tectonic contact in eastern switzerland

摘要

At the tectonic contact between the Penninic Platta Nappe and the Lower-Austroalpine Err Unit in eastern Switzerland carbon and oxygen isotope fronts are preserved at the interface of serpentinites and low-grade regional metamorphic metacarbonates.
