User-friendly interface and wide possibilities of visualization is the key for effective solving of geological tasks.\r\n

\"2D<\/a><\/p>\r\nUnlike \u00a0predecessors, ZondGM2D<\/strong> offers three types of models:\r\n\r\nModel is split by regular mesh of cells<\/em>\r\n\r\nThis type is most useful for solving the inverse problem (automatic density or magnetic susceptibility recovery). Inversion results is a good start choice for further geological and geophysical interpretation. \u00a0A number of inversion algorithms are realized in software, most important are smooth and focused inversion – to get a smooth or piecewise smooth distribution of geophysical parameters.\r\n

\"Combined<\/a><\/p>\r\nModel is presented as set of polygonal bodies<\/em>\r\n\r\nPolygonal <\/a>variant of gravimagnetic section construction that gives more structural approach to data interpretation. At this scheme two-dimensional section consist of series of bodies with arbitrary geometries and specified density and magnetic susceptibility. Due\u00a0to convenient and intuitively clear interface ZondGM2D<\/strong> allows to quickly creating any level of complexity models. The solution of\u00a0the inverse problem for polygonal version of model presents automatic recovering petrophysical parameters and bodies geometry. Joint inversion of gravity and magnetic survey data is able for this case.\u00a0Remanent magnetization<\/a> modeling is available in this mode.\r\n

\"2D<\/a><\/p>\r\nArbitrary layered model<\/em>\r\n\r\nThis type of model is useful for regions with layered geology. ZondGM2D<\/strong> solves forward and inverse problem for density and magnetic\u00a0susceptibility, as well as for geometry of the boundary layers. Joint inversion of gravity and magnetic\u00a0survey data is able for this case.\r\n\r\nCalculations 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.\r\n\r\nIn addition to these algorithms, ZondGM2D<\/strong> presents classic version of the Euler deconvolution, which allows to get distribution of the \u00a0simplest types of gravitational and magnetic sources. Software works with any components of gravity and magnetic fields and do transformations.\r\n\r\nNext transformation are able in\u00a0ZondGM2D.<\/strong>\r\n
