Oksko Ц -Tsnya shaft is a large positive tectonic structure of the East European Platform [1] [2] on the north-western slope of the Volga-Ural anteclise [1] . Named in honor of the rivers flowing through its territory - the Oka and Tsna [1] . Passes south of Murom [3] , between the cities of Gus-Khrustalny and Melenki [4] , through Kovrov , Kasimov to Morshansk [1] . First described in the work of Nikolai Andreevich Theological in 1906.

Description
Oksko-Tsninsky Val is a gently sloping uplift stretched in the meridional direction and consists of two parts — the northern (Oka – Klyazma ) and the southern (Oka – Tsninskaya), which are separated by a low stage to which the segment of the Oka River is timed. The southern part of the Oka-Zninsky Val is located above the ancient Pachelmsky aulacogen [2] . The shaft consists of several dome-shaped brachyanticlines and dome-shaped elevations, separated by synclinal troughs. The shaft structures are asymmetrical — on the western wings of local uplifts, the angles of incidence reach 17 °, and on the eastern ones they do not exceed 1–2 ° [1] .
Formation
It was formed in the Carboniferous and Mesozoic times [5] in the Hercynian era of tectonogenesis (folding) [6] , separating the Moscow syneclise from the southern structures of the East European Platform [7] . Geologist N.S. Shatsky was considered as the southern transverse complication of the Moscow syneclise [8] .
Geological structure and minerals
On the main axis of the shaft, coal rocks , karst [9] limestones and dolomites [10], come to the surface. Karst processes continue at the present time, forming cavities and sinkholes [11] . Outside the shaft, limestones and dolomites are covered by later Permian and Mesozoic deposits [1] [12] . Carbonate rocks on the territory of the Oksko-Tsninsky Val area are developed as minerals [4] . Along the edges of the shaft, deposits of oolitic iron ores are distinguished [13] .
Expressiveness in relief
In the relief, the structure of the shaft is repeated in the eponymous plateau with a relative height of 20–30 m [1] . Oksko-Tsninsky shaft influenced the shape of the Oka riverbed, which flows around it along the northern edge and only downstream crosses the shaft across the strike of the rock layers [1]
