Abstract
A geophysical interpretative method is proposed to depth amplitude coefficient and geometrical shape factor determination of a buried structure from an observed gravity anomaly related to a cylinder or a spherelike structureThe method is based on nonlinearly constrained mathematical modelling and also on stochastic optimization approaches The proposed interpretative method first has been tested on theoretical synthetic models with different random errors at a certain depth where a very close agreement has been observed between assumed and evaluated parameters Subsequent field data have been considered for which the interpreted results by other methods are available for comparison The agreement between the obtained results by the proposed technique and by other geophysical methods is good A statistical analysis has been also carried out to demonstrate the accuracy and the precision of the suggested interpretative method
