| Abstrak/Abstract |
The mathematical modeling of dike or magma intrusion has been done, based on magnetic
data with inversion techniques using MatLab. The magnetic equation was done using a
linear approach to non-linear mathematical models of magnetic data using the Taylor
expansion approach and Jacobi Matrix. The first step, we made a synthetic data forward
modeling from the magnetic equation of dike or magma intrusion cases without errors, and
then add errors to the data. The next step was to do an inversion to get the parameters
sought, i.e., depth and angle of the magma intrusion, by giving initial guesses, and then recorrect solution iteratively until obtained the convergent results. Finally, parameters of
dike/magma intrusion slope orientation and its depth can be determined, and this technique
can be used to get the physical parameters of these geological cases. |
