The differential scaling function: A local estimator of source parameters of potential fields

Summary We present a method to determine the source properties of potential fields by exploring the field at multiple scales. At each scale the depth to the source and the structural index are determined by analyzing the scaling function τ, a dimensionless quantity which defines the scaling properties of the field, and the differential scaling function β. For homogeneous fields, the estimated results are scale invariant. The source properties are determined either by a geometrical method applied to the a single ridge or by solving for the zeros of β.
