Hydrocarbon deposits concentration per unit square in Yamal is more than 100 times greater than the world average. Hydrocarbon deposits are generally located in regions with high modern geodynamic activity. The mantle structure in Yamal area has abnormal features according to seismic tomography. The southern part of Kara sea, Yamal and the western part of Gydan peninsula are situated in a big positive heat flow density anomaly with the epicenter near to Rusanovskoe deposit. Almost all deposits of hydrocarbones in Yamal are situated on the flanks of the West-Siberian rift system and simultaneously in gradient zones of heat flow density.
