Topographic base interpretation revealed symmetric structure of Solikamsk basin lineations. It is caused by a concentric arrangement of anticlinal brows and radial disposition of strike-slip dislocations. Such structure reflects piling up of over-salt deposits from its edge to central part of Solikamsk basin. Slipping of over-salt deposits above salt uplifts could cause its bend and formation of cracks separation favoring downward infiltration of atmospheric waters. Epigenetic processes led to leaching of carbonate material to form near-vertical zone composed collapse-breccias, secondary clay and clayey marl, and also considerable transformation of sulphate, carbonate and aluminosilicate materials with formation of a specific mineral paragenesis (anatase, cadmium-bearing sphalerite, skeletal pyrite).
