Localization of endogenous influence zones in areas with a high level of gas saturation by magnetic field anomalies

Based on the interpretation of the Earth’s magnetic field anomalies and gravity anomalies, the structure of the Arctic lithosphere in areas of increased gas saturation of bottom sediments has been studied. The analysis of density and magnetic sections has shown that the lithosphere in the zones of methane fluxes and gas hydrates is characterized by the presence of thermo-fault that remove fluid flows from the Earth crust and mantle. In areas of aquatories where, according to geochemical studies, methane outputs of deep genesis have been confirmed for the first time, the trajectories of fluid flows coming from a depth of the Earth crust and mantle have been traced on petrophysical sections. The study of the influence of the endogenous fluid-dynamic factor make it possible to optimize the choice of safe shipping routes along the Northern Sea Route in the fields of methane emissions.
