Abstract

Fourier spectrum of the gravity effect due to a horizontal slab with lateral variation of density is derived. By analysing this spectrum a procedure is formulated to determine the parameters of the causative bodyviz. depths to the upper and lower surfaces, width of the horizontal portion having the lateral density variation and the lateral density gradient. Two synthetic models and a field example are discussed to establish the validity of the procedure formulated. This is much simpler than Gendzwill’s type curves method.
