L1 inversion of gravity data is widely used to estimate the discontinuous relief of basement. We used the L1 inversion method to recover a complex model with faults, a smooth feature, and a V-shaped interface. The noise of data, the constraints with errors and the incorrect density contrast are considered in the stability analysis of inversion. The results show that the constrained L1 inversion of gravity data is stable and efficient for complex discontinuous relief of basement.
