Magnetic Prospecting of Ore Deposits
Application ID: 3807
Magnetic prospecting is a geological exploration method that is applicable to certain types of iron ore deposits, in particular those made up of magnetite and hematite. The method consists of measuring the magnetic anomalies (changes in the earth's magnetic field) due to the presence of magnetic ores.
The Magnetic Prospecting app simulates the effect of a deposit of magnetic ore on the earth's magnetic field and predicts the measured anomaly at specified measuring points on the surface. You can import heightmap images or digital elevation model (DEM) files to define the orography of the region as well as the geomagnetic field data for the specified location.
The computation generates a plot of the magnetic field on the earth's surface as well as numerical data of the expected anomaly at specified measurement locations in the region.
This application example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license.
