Difference between seismic-derived and gravity-inversion salt-thickness models, calculated as seismic-derived thickness minus gravity-inversion thickness. Negative values indicate areas where the gravity inversion models a thicker salt interval than the seismic interpretation, while positive values indicate the reverse. Values are expressed in metres and represent model-to-model differences, not measured salt thickness.
