A Generalized Model of Filtration in a Fractured-Porous Medium with Low-Permeable Inclusions and Its Possible Applications

Izvestiya, Physics of the Solid Earth - Abstract—This work generalizes the classical mathematical model of fluid and gas filtration in a fractured-porous medium. It results in a generalized...

Mathematical Model for the Motion of Solutions Taking into Account the Osmotic Effect

Doklady Earth Sciences - The generalized equations of solution motion are given both in porous media and in cavities taking into account the osmotic effect. In certain cases, commonly small...     

Phenomenon of Concretions Occurrence on the Ocean Bottom

The paradox of the long-term existence of ferromanganese concretions on the ocean floor is considered. It is known that nodules do not sink in the less dense medium of liquefied sediments and have been located on the bottom surface since their genesis over many thousands or even millions of years. At the same time, river and sea sludge easily sucks up other objects (of the same density), which in some way fall to the bottom. We propose an original mechanism explaining this paradox, which is based on a combination of three physicochemical phenomena.     

The formation features of landscapes in the Inderskii salt-dome area (Precaspian Hollow)

We present the results from studying the landscapes in the Inderskii salt-dome area: the geomorphological features of the Inderskie mountains, the soil geochemistry, and the species composition of vegetation. A comparative analysis is made of the major salt-dome areas of the Precaspian lowland: Bogdinsko-Baskunchakskii, El’tonskii, Inderskii, and Chelkarskii.
