Annotation:  In article on the basis of the known facts of the movement of asteroids their key parameters are specified (speed of the movement, the sizes, quantity, structure, etc.). Considering that the area of oceans is about 70 % of the Earth's surface, the possibility of falling of an asteroid to the ocean is considered. On the basis of the law of energy conservation the mechanism and mathematical model of impact of an asteroid on oceanic water and impacts of a hydroshock wave on ocean bark is developed. Dependences for determination of pressure in the ocean and also crush zone radius and zone of formation of radial cracks in ocean bark are received. The legitimacy of the received formulas is shown. The numerical calculations indicating that when falling an asteroid radiuses of zones of destruction are commensurable with an average power of ocean bark are carried out. This can lead to the penetration of separate radial cracks (fractures) of ore melts and the appearance of mineral deposits in the oceanic crust. In the radial faults and deep ring cracks, mineral deposits can form
