RT Journal Article SR Electronic(1) A1 De Stefano, Michele A1 Panepinto, StefanoYR 2017 T1 On the approximation of the potential fields when using right rectangular prisms JF Geophysical Prospecting, VO 65 IS 5 SP 1366 OP 1379 DO https://doi.org/10.1111/1365-2478.12468 PB European Association of Geoscientists & Engineers, SN 1365-2478, AB ABSTRACT Due to its simplicity, stability, and efficiency, the use of right rectangular prisms is still widespread for potential field modelling and inversion. It is well known that modelling the subsurface with Cartesian grids has important consequences in terms of accuracy of the results. In this paper, we review the main issues that geophysicists face in day‐to‐day work when trying to use right rectangular prisms for performing gravity or full tensor gravity modelling and inversions. We demonstrate the results both theoretically and through Monte Carlo simulations, also exploiting concepts from fractal geometry. We believe that the guidelines contained in this paper may suggest a good practice for the day‐to‐day work of geophysicists dealing with gravity and full tensor gravity data., UL https://www.earthdoc.org/content/journals/10.1111/1365-2478.12468
