    1. identify the regional signal (steeper slope) from the residual one on the power spectrum graph (gentle). 2. calculate the slope of each 3. Apply the formula h=- slope/4pi. h being the depth you are looking for

    Clic on Magmap/spectrum calculation and display, then follow the steps.
    Depending on which Geosoft version you are using

    Ok, but what's mean K_unit in the depth estimate?

    @geosoftdehispa "K_unit" means Kilo unit, which is your ground unit times 1000 (e.g. 1 kilometre = 1000 metres)
