Solid mineral resources cadastre of the Far-Eastern and Arctic seas shelf deposits is considered in this paper. The information,provided by the cadastre,is differentiated according to each considered deposit with distinguishing on-shore(beach)zone, tidal zone (up 20 m deep) and off-shore zone(up 50 m deep). The cadastre includes several information blocks: mining-geological characteristic of the deposit; hydro-meteorological conditions and aerodynamic local mode of accurence of a placer; ice conditions of the sea (thickness of ice,periods of drifting and freezing and etc.); technological parameters of the placers; geographic,technical-economical and ecological descriptions of the area of the: placers. To the considered in the cadastre groups of deposits modelling and substantiation of the technological structure parameters of marine dressing complexes,optional mining patterns, concentration, dumping and transportation of mineral raw materials were added. A classification of the technological structures of marine dressing complexes, elaborated by the authors of this paper,is presented in mould form. In the classification fields of boundary values of technical and technological parameters of mining,concentrating and transporting equipment from those,requiring additional planning-design and patent-licence study are distinguished.
