Author(s): Marwan Mutib*, Maan H Al-majid and Fadhil A Ghaib
The surveyed area covering about 2000 km2 in the north-eastern Iraq with elevations ranges between 300 to 1900 m above sea level. The study area is located within the foot hill and high folded zones including a number of important anticlines (Aqra, Piris, Barat, and else). The geophysical survey is based on 170 gravity points. The gravity data had been corrected and the Bouguer anomaly was calculated along each point. The 2D modeling technique by using Geosoft Oasis Montaj program was applied for the quantitative interpretation. Six gravity profiles were modelled. The results of this study show that the top depth of the basements rocks in the studied area is around 9 km, and several faults are indicated in the sedimentary sections by gravity profiles. The results of the modelled profiles are identified that the several grabens, half grabens and horsts surrounded by normal and reverse .. View More»
