initial conditions for stress shears of fine-dispersed compacted sediments and soils
on underwater marine slopes and artificial dams with following formation of fast
mud currents with huge catastrophic consequences. The scientific basis of mechanisms of influences of viscous ultraanomaly and hyperanomaly effects [6] provoking
initial laminar flow of NIASSs’ and NIASMs’ dispersions are not considered. The
processes, which follow such flow and occur in phase nanosized zones of particle
contacts in NIASSs’ dispersions aided by siloxane, iron hydroxide, and carbonate
structures are not considered too. The important role of wind waves in the formation
of marine phaseolinic coastal oozes and further action of physicochemical, biocolloidal, and geomechanical factors resulting in formation of turbidite-ooze compositions on basis of IASMs and NIASMs on marine slopes was not shown. There are lack
of investigations concerning the mechanisms of contact nano- and microstructured
dispersion transformation of NIASSs and NIASMs in conditions of their transition
from elastic to plastic state and vice versa. The respective models for the mentioned
processes are not given. Thus, the importance and actuality of stated investigations
are evident.
2 Physicochemical Characteristics of Investigated
Materials
Preliminary initial investigations of transformation processes of polymineral
microdisperse and nanostructured iron-aluminosilicate systems and materials (IASSs
and IASMs) of natural and technogenic origin (iron ores, soils, pelitic sediments,
peloids, natural, and thermodestructed clays, sands, etc.) under the influence of
geomechanical and nanochemical dispersion were done. They showed that as a
result of change of factors of influence on microdisperse and nanodisperse IASSs
and NIASMs, there can occur various interactions between their components [1–6].
Such interactions can include reduction or oxidation, further dispersion or contact
interparticle compaction, Ostwald ripening, change of surface interparticle or interaggregate nanostructured phase composition, chemical leaching, adsorption, adhesion,
cohesion, ion exchange, etc. Such interactions give new properties and change characteristics of IASSs and NIASMs. Such changes mostly appear in the Earth crust and
on its surface as a result of natural or technogenic processes. However, the processes,
which occur in such systems and compositions of materials are still estimated only by
final parameters. But that does not explain the source and the mechanisms of initial
transformations, which cannot be observed easily anytime. There are still no unique,
scientifically proved colloid–chemical ideas concerning the transformation of polydisperse IASSs and NIASMs in conditions of their geomechanical and nanochemical
dispersion in natural geological conditions. And there are also no principal models
of biocolloid–chemical interactions in such systems that can give a possibility to
explain the processes of controlling IASSs and IASMs’ behavior and characteristics. Concerning the said above, the choice of study materials was based on samples
