Underground Brines of the Tunguska Artesian Basin (West Siberian Plate)

A short review on the chemical composition of underground brines is presented. Diagrams of brine saturation of upper-saline, saline, and under-saline formations have been determined with respect to common minerals of the water-bearing rock. It is shown that even brines of 300-500 g/dm3 are not equilibrated with primary (endogenic) minerals, as they all continue to react.
