2-D Inversion of gravity data

This study deals with modeling of gravity anomalies by Compact Inversion Method of Last and Kubic (1983) and Lewi et al (1994). The principle used is to minimize the volume, to maximize of the causative body. The anomalous density distribution is obtained using an iterative technique which is numerically stable and rapidly convergent. This principle can also be adapted to include modeling of gravity anomalies by single density sources. The advantage of this method is that desirable geological characteristics are automatically incorporated into the model with minimum subjective judgments on the part of interpreter. The treatment of noise in data fits naturally into formulations of the inversion procedure The practical effectiveness of this method is assessed by inversion of synthetic and real acquired over chromite ore in Hormozgan province of Iran.
