EULDPH: A new technique for making computer‐assisted depth estimates from magnetic data

A method for rapidly making depth estimates from large amounts of magnetic data is described. The technique is based upon Euler’s homogeneity relationship (hence, the acronym EULDPH) and differs from similar techniques which are currently available in that no basic geologic model is assumed. Therefore, EULDPH can be applied in a wider variety of geologic situations than can model‐dependent techniques. The price paid for this increased flexibility is a heavier burden on the interpreter. Successful interpretation of EULDPH results is partially dependent upon the interpreter’s intuitive understanding of the concept of the equivalent stratum and also partially dependent upon experience with model studies. The theoretical basis, the computational algorithm, and applications of EULDPH to model and real data are presented.
