『Abstract
　The chemical composition, structure, and biomass of the present-day biosphere are discussed with particular attention paid to reproducibility of organisms. It is shown that the Earth's stratisphere (sedimentary sphere) contains significant traces of past biospheres, which determines the biogenic oil generation potential. Based on indications of biogenic oil origin and particular examples, some aspects of the sedimentary-migration theory of oil and gas origin are considered.』
