Geophysics 325 : Gravity, magnetic and electrical methods

MATLAB scripts

C: DC resistivity

• C3.4-WWW.zip Fit a 2-layer resistivity model to the Malagash data set
• C4.3-WWW.zip Fit a 3-layer resistivity model to a field data set. Note that two solutions with the same conductance will both fit the same data.

D: Magnetic exploration

• mag_dipole.m Computes the magnetic field over a buried sphere.
• mag_dipole_movie.m The script shows a movie of the magnetic anomaly of a sphere as the inclination varies.
• mag_slab.m Magnetic field over a buried slab.

• fluxgate.m Illustrates how a fluxgate magnetometer works.
