RT Journal Article SR Electronic(1) A1 HENDERSON, ROLAND G.YR 1966 T1 FIELD CONTINUATION AND THE STEP MODEL IN AEROMAGNETIC INTERPRETATION* JF Geophysical Prospecting, VO 14 IS 4 SP 528 OP 546 DO https://doi.org/10.1111/j.1365-2478.1966.tb02252.x PB European Association of Geoscientists & Engineers, SN 1365-2478, AB ABSTRACT Downward continuation of the field in the neighborhood of a singularity of a magnetic anomaly is used to render the anomaly more two‐dimensional, to make the bottom of the causal body more remote, and to obtain an auxiliary function, φ (O, z), by means of which the anomaly may be interpreted in terms of an equivalent vertical contact or step model. The concept of “apparent depth” is introduced and used in studying depth extent and susceptibility. The methods are illustrated with theoretical and practical examples., UL https://www.earthdoc.org/content/journals/10.1111/j.1365-2478.1966.tb02252.x
