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 for0

Thank you but I mean with Oasis Montaj.0

Clic on Magmap/spectrum calculation and display, then follow the steps.
Depending on which Geosoft version you are using0 
Ok, but what's mean K_unit in the depth estimate?0

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