Abstract
The present paper deals with a simple and rapid approach to depth determination of a buried thin dike using numerical horizontal magnetic gradients. The problem of depth determination has been transformed into finding the zero anomaly distances from observed gradients. Formulas are also given to estimate the amplitude coefficient and the index parameter. The method has been applied to synthetic data and the validity of the method is tested on the Pima copper mine magnetic anomaly, Arizona.
