... from non-marine evaporites now form the major commercial sources of borate – borax, colemanite and ulexite. These major commercial deposits are associated with Neogene volcanism in tectonically active extensional regions at plate boundaries. The most important continental borate provinces are located...

...Yongliang Xiong; Leslie Kirkes; Terry Westfall Abstract In this study, solubility experiments on sodium tetraborate (NaB 4 O 7 ·10H 2 O, borax) are conducted in NaCl solutions up to 5.0 m at room temperature (22.5 ± 1.5 °C). In combination with solubility data of sodium tetraborate in Na 2 SO 4...
