Title: Gravity investigation for detecting The subsurface basement topography Of the western part of behera Governorate, North Egypt
Author: Abou Shagar, S [السيدة محمد السيد ابو شجر]
Abstract: One of the most effective tools for exploration of the subsurface basement topography is the gravity method. The Bouguer gravity map of the western part of Behera Govemorate west of the Nile Delta of Egypt has been analyzed for this purpose. Trend analysis using linear, 2n" , 3", and 4tn orders is used to separate the regional from local effects. The second order trend gave the optimum results when compared with the published works concerning the general subsurface structures in the Nile Delta and its surrounding area. Alternating NW-SE negative and positive anomalous trends are observed. 2-D models along two profiles are examined using the rapid method described by Talwani. Analysis of the obtained models show that the thickness of the sedimentary section increases towards the eastern and southeastern directions where it exceeds 10 km.استخدمت تقنية التحليل الخطي من الدرجات الثانية ، الثالثة والرابعة ، وذلك لفصل كل من التأثيرين المحلي والنطاقي من شاذة البوجير ، وقد أعطت النتائج الخاصة بالدرجة الثانية أقرب النتائج واقعية مقارنة مع الأعمال المنشورة في هذا المجال .
