Description
This is a complete course that will take you step by step to master 3D inversion of magnetic data. This process involves using measured magnetic field data to create a three-dimensional model of subsurface structures, often to identify mineral deposits or geological features. The main aim of this 3D inversion process is to determine the distribution of magnetic susceptibility in the Earth's subsurface by solving the inverse problem of forward modeling. The GM-SYS 3D Modelling system is a 3D gravity and magnetic modelling package for surface-oriented models. A model is defined by a number of stacked surface grids with density, susceptibility and remanent magnetization distributions specified for the layer below each surface.3D models are defined by a number of surface grids with a density distribution (and/or susceptibility & remanent magnetization distribution) assigned to each layer. Layer density may be specified using either a constant density, a vertical density-depth profile relative to a reference surface, or a laterally-varyingdensity distribution defined by a grid. Layer susceptibility may be specified using either a constant susceptibility and remanent magnetization, or a laterally-varying susceptibility distribution.All input grids must also be consistent with respect to the following:-- Grid size (number of rows and columns).-- Coordinate system.-- Cell size and units.-- Grid origin/location.
