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.
