Preliminary data on autigenic mineral formation in natural chlo-ride water discharge sites in the Solonikha river basin (Perm region)

The Verkhnekamskoe Salt Deposit is reflected in the appearance of natural chloride waters on the earth's surface, migrating from the depths as a result of natural factors. To identify the features of mineral formation in such areas, we studied the soil of two springs in the Solonikha river basin (Aleksandrovsky Municipal District of Perm Krai; above the eastern boundary of the salt deposit) with a sodium chloride composition and a total mineralization of 15,13–23,67 g/l. During the mineralogical analysis of the soil, pseudomorphs (on plant detritus) of pyrite, less often barite and calcite were revealed. Visually, a direct correlation is noted between the intensity of pyritization and baritization processes and the total mineralization of water.
