Subsurface Significance of Gravity Anomalies In Kharga Area, Egypt A.R.E.

Abstract

The present study is mainly devoted to the critical analysis of the geophysical data, including the gravity anomalies and the drill hole in- larmations in Kharga area for better understanding of its subsurface structural features that has economic potentiality. Such a critical analysis revealed that the regional structural setting of the area is gcnerally consists of majör faulted blocks. These faults had affected the basement complex and the cverlying sedimentary suc- cession by throws having different magnitudes ranges between 50 to 250 meters. Some of the faults which vvere detected from the residual - anomaly map indicate the presence of tsvo fault trends striking NW- SE and NE—SW parallel to the Gulf of Sucz and Gulf of Aqaba respecti- vely. It is concluded that the maximuın thickness of the sedimentary succession overlying the basement complex which recorded in the area is about 950 meters.
