ABSTRACT
This paper describes a new inversion algorithm for 3D gravity data based on a new evolutionary optimization algorithm, inspired by the life history of the avian family of cuckoos. The newly developed method was applied to synthetic data to demonstrate its suitability and then applied to real data. Two case studies are presented: (1) salt dome case study from Charak region (Iran) and (2) Obama geothermal field (SW Japan). The results of the 3D gravity inversion of two sets of real field data, yield geologically plausible models with the estimated depths and shape that fit well with previous geoscientific studies.
