The book "Atlas and Data of Solid-Solution Equilibria of Marine Evaporites" provides a comprehensive compilation of data on the equilibria of solids in marine evaporites. It addresses gaps in the existing literature and serves as a valuable resource for scientists and professionals dealing with the chemistry of seawater and the development of salt solutions. The authors, Eberhard Usdowski and Martin F. Bach, have collected and processed data over several years to enable a better understanding of the processes of dissolution, precipitation, and transformation of solids. This work is both scientific and educational, aiming to promote the application of the data in the geosciences. It is emphasized that despite the abundance of solubility data, significant gaps remain, particularly at high temperatures, highlighting the need for further research.
