Software supports different types of sources for can be used for interpretation of different types of self-potential data.\r\n
<\/div>\r\nSelf-potential field method is based on studying of the natural electric fields that generate in rocks because of various physical and chemical processes. Small self-potentials of diffuse-adsorption and filtering nature exist practically everywhere. Intensive fields of redox nature are observed only over sulphide and graphite deposits. As a rule electronic conductors located in the ionic media are the search objects of self-potential field method. Electric charges as sources of natural electric field are formed on the boundaries of such objects.\r\n
<\/div>\r\n\"sppic1\"<\/a>\r\n\r\nZondSP2D<\/strong>\u00a0represents ready solution for self-potential method, and solves wide range of problems from mathematical\u00a0modeling<\/a>\u00a0\u00a0to field data \u00a0interpretation. Convenient interface and variety of data visualization features allow to solve wide range of geological problems with maximum effectiveness.\r\n
<\/div>\r\nZondSP2D\u00a0<\/strong>uses simple and clear data format which allows easily combining various arrays and topography information. Software fully integrated with ZondRes2d<\/strong> software, so importing of resistivity background model is very easy.\r\n
<\/div>\r\nTo each object of model \u00a0resistivity and sources can be assigned. Types of sources different and\u00a0 depends on considering problem. It can be border redox-oxygen nature sources or volumetric sources (poles or oriented dipoles). For redox-oxygen case very convenient functional is used to set source intensity vs depth. Area of volumetric sources presence can be limited by user defined polygons.\r\n
<\/div>\r\nAs the general task of the program is inversion of source currents, some approaches of inverse problem are used in ZondSP2D<\/strong>, basic of them are: probability inversion<\/em> \u2013 helps to get more stable source\u00a0 distribution, occam inversion<\/em> \u2013 can be tuned in different way to get alternative results for different settings and parametric inversion<\/em> for small number of parameters problem.\r\n\r\n\"sppic2\"<\/a>\r\n\r\nBasic features:<\/em>\r\n
