Simultaneous nano-, micro-, and macrotransformations of marine ore and peloid sediments under the influence of microorganisms as a part of biogeocenosis composition have been investigated. It is shown that during the processes aided with biogeocenosis, the hydrational dispersion of sediment mineral compounds takes place. It happens with their stratification into several layers. The layers separated from each other differ in density, rheological, mineral, physicochemical, and geomechanical parameters. Moreover, it gives a possibility to develop the nanotechnologies of their enrichment and application on this basis. It is established that in disperse marine and salt lake sediments based on iron-aluminosilicate materials (such as peloids (therapeutic muds), turbidite-pelitic structures, and biocolloidal iron ore compositions), the processes of their further fracturing are significantly accelerated by the action of microorganism metabolic surface-active products. It is shown that deep synergic destructive transformations occur in mineral components containing iron and calcium-containing compounds and clay minerals. Mentioned complex mechanisms of biocolloidal transformation of marine iron-aluminosilicate sediments and regularities of their nanostructural transformation allowed to offer the basics of new effective enrichment technologies with separation of iron concentrate, technologies for receiving peloids with enhanced therapeutic properties for balneological needs and for the regulation of ecological balance in seas and oceans in conditions of increasing negative anthropogenic processes. |
