The technology of joint usage of qualitative and quantitative methods of interpretation of gravimetric data id examined. Field separation by formal procedures for the series of components with different depths is suggested ti realize taking inverse task solution in account, while solving of inverse task themselves is proposed to conduct using the results of fields separation. Such technique allows to approach to required construction model of the examined object of geological medium with every step of interpretation process. At the initial stage of interpretation process, Vector system is used for building the image of geological medium, this system allows to get 3D distribution of quasi-density, reflecting some elements of physical geological model. The results of vector scanning are using for detalization of geological hypotheses and setting a priori restrictions in consequent solving of inverse task. Then miltiple solving of inverse task is executed via the mounting method. The obtained complex of partial solutions is transformed in net distribution of possibility of revealing the anomaly forming object that is an appropriate geo-density model. This model has real 3D coordinates and characterize distribution of anomaly forming masses in the examined volume of geological medium. Usage of geoinformation systems for storage of starting and resulting gravimetric data, as well as for transferring the intermediate results of interpretation between other programs is seemed to be quite suitable. Practical examples testifying about the efficiency of presented technology are described.
