    Abstract
    Analysis of the total intensity magnetic data over the western Andaman shelf has been carried out for determination of depth to magnetic basement using the Analytical Signal and Wemer Deconvolution methods. The basement depths are refined with optimisation procedure of iteration modelling. The depths derived from these methods match well with the acoustic basement mapped by seismic reflection survey across the Andaman shelf. The interpretation by these methods demonstrates the rapid utility in virgin areas for deriving the first order basement configuration quickly. The gradual slope of the basement from west to east on the western. Andaman shelf may be attributed to the ongoing process of the subduction of the older crust in the Sunda Trough
