We analyse the residual mantle Bouguer gravity anomaly (RMBA) from 19 oceanic transform ... transform on the Mid-Atlantic Ridge, at the same map scale. Figure 3: Results of 2D forward models ...

The Bouguer anomaly map shows a gravity low of −35 mgal (the ‘Niger Delta Minimum’) which occupies a large part of the sub-aerial Niger Delta, and a gravity high of +40 mgal (the ‘Ekenie ...
