The periodicity of accumulation of phosphorites, cupriferous sandstones and shales can be considered with respect to global changes. This approach clearly links unique and large deposits with the Panotia and Pangea supercontinents. The Panotia supercontinent provided conditions for the formation of large deposits of the African Copperbelt, White Pine (USA), Ainak (Afghanistan). Close in age are large phosphorite deposits in the Khubsugul, Yun'nan, and Karatauss basins. The Pangea favored the appearance of the deposits of the Dzheskazgan group in Kazakhstan (C2-3) and copper deposits in Rotliegende and Zechstein of Europe: Mansfield, Sangerhausen, Richelsdorf, and others (Germany), Lubin-Sieroszowice gigantic deposit (Poland). The Phosphoria gigantic deposit is also of Permian age. However, the world maximum phosphorus accumulation occurred in the Cenozoic (the Algeria-Tunisian, West Sahara, Moroccan, Florida, Californian, and other basins). Taking into consideration the genetic model for red-bed copper deposits, the link with supercontinents is quite natural. Large deposits require thick layers of red-bed ore-generating accumulations and carbonaceous geochemical barriers. Carbonaceous geochemical barriers are made up of carbonaceous phases of biosphere rhythms, which always appear against the background of ocean level rise. Red-bed formations are generated at the final calcium phase of biosphere rhythms, which follows directly after the carbonaceous (Malinovsky, 2006). Formation of thick continental red-beds is associated with climatic aspects of supercontinents, including the formation of gigantic ice covers and the near-absence of the humid tropical belt. In lower and middle latitudes of supercontinents, the climate was continental and arid. Many red bed formations accumulated when world ocean levels were low and during initial extension of the continental crust. Large exogenic copper deposits occur at glacioeras and subsequent arid epochs. Progressive development of continental glaciation stimulates the formation of large copper and phosphorite deposits. Incidentally, it refers to all other Phanerozoic ore-bearing and oil-gas deposits, which might be due to intensification of oceanic currents, which form biosphere rhythms and determine degree of their contrast. Hence, the formation of large deposits of phosphorites, red-bed copper deposits proceeds with a periodicity equivalent to the Wilson cycle of the development of supercontinents (400-450 Ma).
