N2 - Results of the studies into the effect of trap magmatism on the geochemistry of gases (free and dissolved in water) and their zoning within the boundaries of north-western regions of the Siberian Platform are reported. The maximal paleotemperatures at the moment of trap intrusion reached 650 �C at the contact for the major productive horizons: Silurian (Devilish), Ordovician (Baikit), and Cambrian (Deltulino-Tanachinsky, Abakunsky, and Moktakonsky). Hydrocarbon gases in the free and water-dissolved phases were subjected to degradation in the most active form. For instance, carbon dioxide dominates, with its content more than 90 vol. % and methane content up to 5 vol. % in intrusion-affected zone at a distance up to 100 m, while at a distance of 250 m CO2 concentration decreases to 30 vol. %, and CH4 concentration increases to 60-70 vol. %. No significant effect of the thickness of intrusion on gas composition was revealed.
