Gravity data are often used for delineation of the lateral and vertical extension of mineralized bodies buried at diferent depths. Various parameters associated with the buried bodies are the primary concern for mineral exploration purposes. Hence, a reliable and efcacious interpretation method is developed for the delineation of gravity anomaly data over the 2D vertical and horizontal sheet with fnite length and width associated with mineralized bodies. The parameters viz. amplitude coefcient (k), location (x0), depth to the top of the body (h), length of the sheet (L), and shape factor (q) for 2D vertical sheet type structure and depth (h) and width (w) of the sheet for 2D horizontal sheet were resolved. Restricting x0 and q has given very reliable results for the 2D vertical sheet, and the w for 2D horizontal sheet shows the problem of equivalence. However, in all cases, the delineated parameters are within the expected uncertainty. The present interpretation method was applied to synthetic and noisy data and three feld examples from the USA, Canada, and Sweden for mineral exploration purposes. It has also been seen that the present study is more reliable in delineating the actual structure associated with mineralized bodies for the 2D vertical and horizontal sheet-type structure. The delineated parameters are in outstanding agreement with the earlier works, borehole information and also updated the actual subsurface structure.
