THE FORECAST OF HIDDEN ORE MINERALIZATION WITHIN THE NORTHERN SLOPE OF THE ALDAN ANTECLISE ACCORDING TO THE DATA OF ELECTRIC EXPLORATION AND GRAVIMAGNETIC FIELDS

The generation and storage capacities of Neocomian and Jurassic sediments of the northern part of Western Siberia are evaluated. Variants of biogenic and abiogenic methanogenesis are considered. Tectonic and hydrothermal mechanism of the formation of gas pools in Cenomanian sediments is proposed. The youngest Cenomanian gas pools are predicted to be widespread northward under the Arctic Ocean bed. The method of seismic data integration and tectonophysical modelling based on it is proposed in order to search for hydrocarbon accumulations.
