N2 - The spectral analysis of gravity anomalies due to slab like structures with linearly varying density using the Hartley transform, a real valued replacement for the well known complex Fourier transform which is conventionally used in such an analysis, is presented. Being a real valued function, it has specific advantages in terms of computation time, memory and interpretation compared to its progenitor, the Fourier transform. The method is illustrated with a theoretical example and field example from across the mid-oceanic ridge, i.e. 90 east ridge corresponding to latitude 5°N and 5°N and longitude 80°E and 120°E. The results of both the theoretical and practical examples agree well with those of the other conventional methods.
