Analysis of low-frequency component of magnetic and gravity fields of the Siberian cratone has been performed. Relations between regional magnetic and gravity anomalies with magnetic and density heterogeneities in the Earth's crust and upper mantle which were formed during the making of large magmatic provinces: trappean, alkaline-ultrabasic and kimberlite ones have been shown. Tectonic control of magmatism with large systems of regional deep riftogenic faults related to zones of the lithosphere stretching has been substantiated.
