3-D Euler deconvolution method for estimation of gravity anomalies depth (Case study: Ajichai salt dome, East Azarbayjan province, Iran)

The voluminous gravity and magnetic datasets demand automatic interpretation techniques like Naudy, Euler and Werner deconvolution. Of these techniques, the Eulerdeconvolution has become a popular choice because the method assumes no particular geological model. However, the conventional approach to solving Euler equationrequires tentative values of the structural index preventing it from being fully automatic and assumes a constant background that can be easily violated if the singular points areclose to each other. In this paper, we used Geosoft Oasis Montaj 6.4.2 software andMATLAB programming and applied the Euler deconvolution technique, Analytic signal method and vertical and horizontal derivatives to a gravity dataset collected from theeast Azarbayjan province of Iran
