ZondGM2D new software for 2D gravity and magnetic survey combines the features of two predecessors ZondMag2D and ZondPGM. The program is designed for two-dimensional multiprofile interpretation of gravity and magnetic land / boreholes / aero data.
ZondGM2D is a ready solution for the interpretation of gravity and magnetic survey data, and presents a wide spectrum of tools from mathematical modeling to the interpretation of field data. User-friendly interface and wide possibilities of visualization is the key for effective solving of geological tasks.
Unlike predecessors, ZondGM2D offers three types of models:
Calculations are made taking into account geomagnetic parameters of the study area, such as the declination and inclination of the magnetic induction vector, the value of the normal field, the magnetic susceptibility of the host rocks, the topography.
In addition to these algorithms, ZondGM2D presents classic version of the Euler deconvolution, which allows to get distribution of the simplest types of gravitational and magnetic sources. Sowtware works with any components of gravity and magnetic fields and do transormations.
Removing of background component is realized in two ways — by using the median in window or in substrating air upwarding field. Special algorithm of selective wavelet filtering for data denoising is used in software.
ZondGM2D works with simple text files, also supported well-known formats, or arbitrary columns test file. The interpretation results can be exported to different graphics format such as Surfer or Autocad, also text files and Excel worksheet.
While software 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 ZondGM2D 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.
