The aspects of marine sediment behavior in conditions of viscosity ultraanomaly effect [1] and biogeocenosis influence [2] on layer-by-layer separation of sediment suspensions and on ecological balance in marine basins [3] have been studied by the complex of physicochemical, biocolloidal, and physicochemical geomechanics methods. It was established that the biocolloidal influence of biogeocenosis on suspensions of iron-aluminosilicate sediments composed of turbidite-pelitic, peloid and iron ore oozes leads not only to their stratification, but also to changes of their chemical and mineral composition in suspension layers. Such structural phenomena were established for the first time. Their mechanisms, which depend on the aspects of the biocolloidal transformations in biogeocenosis presence and regularities of nanostructural transformation according to the laws of physicochemical geomechanics, were substantiated.
The mechanisms of marine iron-aluminosilicate sediment transformations by nanostructural anomalous transformations are proposed. They allowed considering different technological ways to control them, for example, for the purposes of iron ore enrichment, medical application of peloids, and control the ecological balance in depths and on surface of oceanic and marine basins in conditions of exponentially growing various negative processes, etc. The most interesting is the last one example, which has a global importance for the development of marine biocolloid ecology. However, the successful development of such multidisciplinary and costly branch needs the international cooperation between scientists and specialists of different professions.
