Advanced Methods of Joint Inversion of Multiphysics Data for Mineral Exploration

Different geophysical methods provide information about various physical properties of rock formations and mineralization. In many cases, this is mutually complementary. At the same time, inversion data for a particular survey subject to considerable uncertainty ambiguity as causative body geometry intrinsic property contrast. One productive approach reducing jointly invert several types data. Non-uniqueness can also be reduced by incorporating additional derived from available geological and/or in area reduce searching space solution. This incorporated form joint multiphysics paper presents an overview main ideas principles novel inversion, developed over last decade, which do not require priori knowledge specific empirical or statistical relationships between different model parameters their attributes. These approaches are designated follows: (1) Gramian constraints; (2) Gramian-based structural (3) localized (4) focusing constraints. We short description mathematical foundations each these discuss practical aspects applications mineral exploration.
