Graviseismic structure of the earth’s crust and its five-oceanic geostrophe

Background. The priority positions of Russian geology and geophysics have been reliably supported by large volumes of mineral resources of Eurasian proto-ocean/EAO from ancient Arctic to Middle East. This ocean bordered on all its sides by four other proto-oceans that were opened step-by-step to different sizes between Gondwana, Europe and Asia with Siberia (G-E-A).

Aim. Graviseismic modeling of the Earth’s crust as a basis for RTOE-determination of four tectonic (rifto-, thalasso-, oro-, & epeiro-genic) regimes and a five-oceanic geostrophe of the Earth with two circumpolar and three intercontinental oceans.

Materials and methods. Collection and integration of actual geological and geophysical data on the world’s petroleum and mineragenic provinces to carry out a four-segment (RT-TO-OE-ER) zoning of the Earth’s crust and a sequence stratification of four system tracts (UST-MST-DST-LST formations) taking into account global fluctuations (up, max, down, low/min) of the sea level.

Results. Graviseismic identification of eight geostrophic plates of the modern Earth’s crust with its four-segment zoning and seismo-geological stratification into 12 global sequences.

Conclusion. A new graviseismic concept of a five-oceanic geostrophe of the Earth’s crust has been developed, which is capable of elucidating both past and future stages of the tectono-stratigraphic evolution of sedimentary provinces since the origin of the World Ocean.
