Abstract

The natural bitumen (NB) localization finds in the archipelagos of Russian Arctic Western segment is considered. The nature of their appearance in connection with the geothermal regime of the subsurface is discussed. Based on numerical simulation, temperatures and heat flow density are calculated in 2D geometry along seismogeological profiles and in 3D geometry for the Franz Josef Land isometric structure. It is concluded that all the noted NB manifestations are genetically related to hydrothermal activity, the signs of which are adequately recorded in the geotemperature field.
