Abstract:

 The study area located in southern part of Iraq, it covers about 4009 Km². The data used in this research consists of Bouguer anomalies (Regional and Residualanomalies) with scale of 1: 250 000. These data are mosaicked and clipped for the area of interest. The main interpretation of regional gravity map with contour interval 0.5 mGal showed three anomalies in the study area with different amplitudes and shapes. The main interpretation of residual gravity map with contour interval 0.1 mGal showed negative and positive anomalies with different shapes, sizes, and trends. It gave a good conception about the anomalies. The map could be important in hydrocarbon exploration. Two enhancement methods applied on residual anomalies data to obtain more information about their location, extent, size, shape, and trends, as well as information about faults and tectonic boundaries. The research illustrated that the convolution filter-kernel 7*7 horizontal is effective and gave better result to conception the gravity anomalies than convolution filter-kernel 7*7 vertical. In addition, the 3D enhancement map showed that some faults and tectonic boundaries, follow NW-SE trending were almost identical with the tectonic boundaries between (Najaf – Abu Jir – Hadhar Subzone) and (Tikrit – Amara Subzone).
