Abstract Based on a robust two-dimensional low-order polynomial fitting and weighting iterative algorithm, the gravity anomalies field of the synthetic models and those in the Sichuan-Yunnan region measured on the surface are separated vertically. The separated fields of strata with different depths from the measured gravity data are qualitatively compared with the results calculated by the interpolation-cutting potential field separation method and the geological structure map of the area as well. The results of comparison indicate the algorithms proposed in this paper are portable and reliable and can be helpful to fine inversion and interpretation of later geological structures, and other in-depth research or analysis.
