lithosphere

The purpose of the study. It needs to substantiate that sources of magnetic anomalies with wavelengths of the first thousand kilometers detected at the present time might have a magneto-mineralogical origin due to the existence of magnetic minerals at the mantle depths, in particular magnetite, hematite, native iron, as well as iron alloys. It should be also shown that present temporal changes of long-wave magnetic anomalies should be induced by changes of the magnetic properties of these minerals due to thermodynamic and fluid modes.

Research was conducted on the deep structure of sedimentary basins located in the continent – ocean contact zones characterized by increased seismicity, volcano eruptions and other disastrous phenomena. Sedimentary basin formation is associated with processes going on in the upper mantle and specifically in the asthenosphere. From the asthenosphere to the crust, diapirs branch off that are channels by which deep fluids bearing earth-degassing products penetrate into sedimentary basins, being an additional source of hydrocarbons.

Multiscale pre-, co- and post-seismic deformation processes from the local, regional and strongest world's earthquakes in the Earth lithosphere according to the extenzometric measurements on the short quarts extensometer of RGS “Beregove” in Ukrainian Transcarpathians are considered. Some features of the propagation of such strains in the Eurasia lithosphere are traced.

Based on the continuous series of observations we determined the changes of absolute and regional velocity of vertical crustal movements, their spatial distribution and relationship with the tectonic structure of the region. The accumulated research results indicate the necessity for systematic studies of the impact of various geophysical factors on the stability and permanent displacement of plants and their relation to seismic activity.
