Results of the study provided with a complex of physicochemical, rheological and theoretical methods showed that nanochemical hydration processes going through structure defects in iron-aluminum silicate solid rocks of Earth Crust are main factor of their dispersing due to cracking. In conditions of uneven mechanical pressure change on Earth crust materials, the process of cracks formation intensifies and fastens. Likewise, it can be conducted by macro- and microdispersion formation while additional stresses, e.g. drilling. For the first time it is showed, that crack formation in conditions of mechanical pressure can be followed by microseismic phenomenon (microearthquakes), and as to drilling – by considerable increasing of water and aqueous solutions penetration from depths on surface with environment pollution [1-3]. Complex physical, biocolloid, physicochemical and geomechanic models of such processes are given. On their basis, weakening or strengthening mechanisms of interphase contact interaction of mineral colloid and microparticles in dispersions aided with iron and silicon hydroxide nanoclasters (nanoparticles) are being described.
Nanostructural reasons of sediments and soil rheological properties changing in conditions of solid iron-aluminum silicate rocks dispersion are considered. The conditions for established, for the first time, phenomenon of ultraanomaly of dispersion viscosity and possibilities of its practical application are considered too.
