SP anomaly over doable line of poles-interpretation through log curves

Abstract

In the analysis and interpretation ofsp anomalies, two-dimensional finite sheet models are equated to the double line of poles. The profiles over such a model being asymmetric with a minor positive peak and a major negative peak, a double logarithmic curve matching technique simpler than that of Meiser is suggested in the paper for easy and unique solution for all values of depth, dip and length. This technique along with a few others have been tested on two profiles across the sulphide deposit from the Rakha Mines, Singhbhum copper belt, India.
