Carnallite-halite rocks are the elements of halogenesis’ final stage. Carnallite setting have to follow after sylvinite setting. At the real cut (Gremyachinskoye field also) such succession is disturbed and foundations of those formations proceed of potassium accumulation. Structure of those rocks reflects the receipt in basin with evaporated brine of slightly evaporated solution. NaCl and sometimes KCl are salting out and formed ground halite and rare sylvinite- carnallite rocks.

The analysis of data on geo-ecological problems of development of potash deposits. The basic group of negative processes that arise in the process of developing the potash deposits. The main directions of research within geoekologicheskih promising areas in the Saratov region.

The paper presents the results of composition examination of the uppermost of the Pogozhskaya rhythmic member from the northern near-slope fringes of the Caspian Region. The potassium-bearing horizon encountered there is determined to have resulted from the demineralization stage overlapping the carnallite and the bischofite stage deposits.

During long-term operation of oil and gas fields in the groundwater on their territory are formed hydrogeochemical anomalies expressed primarily chlorellaman type chemical composition, typical of the zone of active water exchange. The formation of the chemical composition of groundwater is influenced by many factors, both natural and manmade.
