Abstract
In the present paper, a simple numerical method is developed to estimate the depth of a buried spherical ore body from the zero points of the vertical magnetic anomaly. The depth determination problem from the characteristic distances has been transformed into the problem of finding a solution of a nonlinear equation of the form z = f(z). Procedures are also formulated to estimate the magnetization inclination and the magnetic moment of the sphere. The method is tested on theoretical data with and without random errors and also on a field example from Bankura area in West Bengal, India.
