Full magnetic gradient tensor from triaxial aeromagnetic gradient measurements: Calculation and application
TL;DR: In this paper, the authors used triaxial aeromagnetic gradient measurements for deriving the full magnetic gradient tensor (MGT), which is the spatial change rate of the three field components of the geomagnetic field vector along three mutually orthogonal axes.

Automatic lineament extraction from potential-field images using the Radon transform and gradient calculation
TL;DR: In this article, the Radon transform (RT) was combined with gradient calculation to process gravity or magnetic data and to realize automatic detection and extraction of lineaments, which can deal with the condition that there is at least one linear section in a specific direction or separate linear sections may belong to one lineament.
