【英文介绍】

?

ZondGM3d program is designed? for three-dimensional interpretation of gravity? and magnetic data by (land and aero variants). Anomalies of gravity caused of different dense heterogeneity are investigated in gravity survey. Influence of host rocks? and surrounding topography is excluded by subtraction of? the normal field and reductions. Magnetic survey is studied field generated by rocks that contain ferromagnetic minerals. Connection of measured on the surface field with magnetic properties of rocks allows to conclude about existence of? magnetic objects.

ZondGM3d represents ready solution for gravity and magnetic methods, and solves wide range of problems from mathematical modeling? to field data processing and interpretation. Convenient interface and variety of data visualization features allow to solve wide range of geological problems with maximum effectiveness.

?

ZondGM3d uses simple and clear data format which allows easily combining various systems of observation, including different variants of the topography setting up and other additional information.

?

Special graphics mode? that allows to visualize data in the freandly form is presented.

Some variants of three-dimensional model display in the form of various sections and isosurfaces are realized in the program.

?

Important stage which prevents field measurement is mathematical modeling of petrophysical structure of work site. Modeling gives a chance? to make a choice of optimum parameters of the observation system for decision of formulated geological problem.

?

As the general task of the program is inversion of density and magnetic susceptibility, some variants of inverse problem decision are realized in ZondGM3d, basic of them are: smoothing inversion – to get smooth model and focusing — to get? piece-smoothed model of petrophysical parameters with depth.

?

While program was designed special consideration given to a priori data accounting. Because of equivalence of inverse geophysical problems, quality of the obtained results strongly depends on the amount of a priori data used. In ZondGM3d there is possibility of weights setting for measurements, fixing and limits making of changing features of different cells, using of a priori model as reference? in inversion. There is also possibility to import and display results of measurements by other methods and cross-boreholes data that improved quality of results.
