Precipitation and dissolution behavior of carbonates plays a major role for the formation of sediments, sedimentary rocks and in man-made constructions. Mechanisms and kinetics are strongly related to the physicochemical conditions, specific reactions at the solid liquid interface and mineralogy. Experimental, theoretical and field studies are greatly appreciated to crosslink results from various individual approaches. In particular, this session encourages contributions on the application and verification of the traditional and non-traditional stable isotope systems as proxies in (bio)geosciences e.g. using carbonates as archives.
