Magnetic depth estimation plays an important role in magnetic interpretation. A complete quantitative interpretation of potential fields data aims to estimate three types of information about sources of geologic interest: the depth, the dimension, and the contrast in the relevant physical property. Such an interpretation suffers from inherent ambiguity. It is impossible to obtain all three types of information simultaneously without other a priori information. In many applications, we are often interested in depth more than either dimension or physical property contrast. Thus, different quick methods have been developed, over half a century, to estimate the magnetic depth. These methods...
