The distribution of MAGSAT scalar anomalies is compared with locations of major tectonic boundaries in Asia. Foldbelts separate large‐scale positive and negative anomalies inside and outside the Siberian Platform, and sediment‐filled aulacogens within the Platform separate the anomalies into two parts which overlie the Anabar and Aldan Shields. Tectonic boundaries appear to exercise some control over the extent and distribution of the satellite‐observed crustal anomalies.
