Euler deconvolution is commonly applied to magnetic and gravity interpretation problems. For the deconvolution to be successful, care must be taken to choose parameters properly. 1. The interpretation problem must be appropriate to the method (only one depth to be estimated at each point). 2. The field must be adequately sampled, with no significant aliasing. 3. The grid interval must fit the data and the problem. 4. The gradients (measured or calculated) must be valid. 5. The deconvolution window size must be at least twice the original data spacing. 6. The structural index in use must be appropriate to the expected geology. If these are not done, the process will yield grossly misleading results. An example from southern Africa is used to demonstrate the deleterious effects of poor parameter choice.
