ZondPGM program is desined  for two-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.

Unlike ZondMAG2d, this program uses a polygonal variant of gravimagnetic section construction that gives more structural approach to data interpretation. At this scheme two-dimensional section cosist of series of bodies with arbitrary geometries and specified density and magnetic susceptibility. Due to convenient and intuitively clear interface ZondPGM allows to quickly creating any level of complexity 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.

Polygonal modeling of gravity and magnetic data in ZondPGM

As input data the software uses the values ??of anomalous magnetic and gravity fields, elevations of measurements observed along any profile.

ZondPGM uses simple and clear data format that allows combine easily various systems of observation, including different variants of the topography setting up and other additional information. Well-known data formats are also supported.

ZondPGM represents ready solution for interpretation of potential fields  data and solves wide range of problems from mathematical modeling to processing and field data interpretation. Convenient interface and ample opportunities of data presentation allow solve set geological problem with maximum effectiveness. ZondPGM is essential tool for interpretation of the gravity and magnetic, complex interpretation, and also in the course of students studying and for geophysics beginners.

ZondPGM has wide set of tools for mathematical modeling of gravity and magnetic fields. In the software also there is a possibility to import and display results of measurements by other methods and cross-borehole data that improve interpretation results. Besides this, algorithms of polygon parameters and geometry inversion are included. They allow correct automatically parameters of objects.
