susceptibility

large and negative values in magnetic susceptibility
I converted 4 layer, at various depth, using GMSys-3D. layers at depths of -250, -500, -750, -1000 m depth. before converting, I used magmap to calculate the apparent magnetic susceptibility for each layer to be used as lateral distribution. I converted the output from magmap filter to be in MicroCGS for GMSys3D. results…
Negative apparent magnetic susceptibility values
Hi, I have been trying to derive near surface apparent magnetic susceptibility from aeromagnetic survey data. In order to do this I have been applying high pass butterworth filters (experimenting with different wavelengths) to try and isolate the residual field and then performing an apparent susceptibility calculation…
