PP‐35The epochs of global cooling are referred to as “global geological winters” [1]. During theEarth’s history the global winters with poor vegetation and low increase in the mass of thecarbon‐hydrogen layer were followed by the epochs of global climate warming and luxuriantbiosphere as “global geological summers”, which are characterized by an increased mass ofthe carbon‐hydrogen layer and oil formation intensity.It is shown that “the global summers” in the Ordovician, Carbonian and Cretaceousmake the biggest contributions to the World Ocean level, which corresponds to the epochsof maximal breakdown of super continents [1]. The zones where the continents broke apartwere well warmed up with the heat from the Earth’s bowels, and life was intensivelydeveloping there. Systematic changes in the geographical location of the continents exposedthem to different climate conditions and promoted the evolution of living organisms. In thisconnection, an investigation of Phanerozoic biodiversity variations, cyclic mass variations ofcarbon‐hydrogen layer as the main factor of oil formation, and explored oil reserves as aquantitative index of oil accumulation is appealing.The foregoing shows that all phanerozoic time dependences of the number of existingand extinct genera of marine animals, mass of carbon‐hydrogen layer, explored oil reserves,and the number of oil‐bearing basins discussed above exhibit a cyclic character with periodicincreases in the midpoints of geotectonic cycles and decreases at their boundaries. Thisclose concordance of temporal changes in quantitative indicators of various geospherebiosphereprocesses is validated by the high calculated values of pair correlation coefficients.It should be noted that the results on cyclic oil formation‐accumulation and globalgeospheric‐biospheric processes in the Earth’s history obtained in this work not only explainthe relationship between the cyclic changes in oil formation and accumulation and thevariation of marine animal biodiversity in the Phanerozoic but could also be used to extendthe theoretical view of the biosphere evolution over the Phanerozoic.References[1].
