The gravity and magnetic responses of extensional sedimentary basins vary wi th the stages of basin development. The major observed gravity responses are regional gravity highs, reflecting crustal thinning, and gravity lows, reflecting low-density sediment infill. Mafic bodies may develop beneath the area of maximum extension as a result of mantle depressurisation and crustal rupture. These may cause regional magnetic anomalies and add to gravity highs. The observed gravity field over a rifted area depends on the relative contributions of the sources of the gravity highs and lows. The observed regional magnetic field depends on the degree of development of mafic bodies.
