translate geophysics to english - residual anomaly

Gravity data that has been further refined by removing regional trends to better reveal local variations.

In geophysics, residual anomalies emphasize the smaller-scale gravity signals often associated with intrusions, ore bodies, or near-surface structures. By filtering out the long-wavelength effects from geology, geophysicists can sharpen their focus on localized density contrasts and more effectively interpret features that might otherwise be masked by broader background signals.
