Reconstruction of Tethyan Salinity Through the Extrapolation of Present-Day Physicochemical Data

The paleosalinities of Tethys over time have been reconstructed through the use of environmental data enabling their evolution to be retraced from the Murgabian to the Tortonian. This reconstruction required the use of numerous parameters of various environments: marine, continental, and margino-littoral (transitional). It has been conducted by the extrapolation of present data on the physicochemistry of waters, sedimentology and the nature of the environment to ancient stages. The paleosalinities have been corrected for each period according to repositioning of latitudes and post-Triassic variations of climate.
