Regional aeromagnetic data in the northern part of the West Siberian Basin of Russia show elongate highs with amplitudes on the order of 200 to 500 nT. These highs are interpreted to represent basalt-filled grabens of Triassic age. The geometry of gradients along the flanks of the magnetic highs permits the interpretation of specific faults as well as accommodation zones, and these features clearly are related to existing gas production. This tectonic interpretation can be used to define details within known productive areas as well as to point out analogous locations for exploration.
