Geophysical implications of North Hurghada Area, Northern Red Sea, as revealed from gravity and aeromagnetic data

Abstract EN

-T his study is ma inly devoted to the existi ng gravity and aeromag ne tic a no rna lies of th e no rt he rn Red Sea and irs ju nc tion with the Gulf o f Suez.

The tectonic eleme nts as we ll as th e subsurface str uc tural fea tu res a nd their rc l.uions to the ev ol ut io na ry stages of th e Red Sea o peni ng are considered he re .

T his study has reve aled tha t : 1) T he co ntinental c ru st in this area is tectonically affec ted by specific system of fau lting as a result of tensional stresses acting nearly :"-15"E-S-15°W .

2) T he tectonic ele me nts ac ting in this area are certainly diffe ren t fro m th ose in the ce ntra l and sou thern Red Sea .

Deep-seated norma l fau lt system tren ding NW-SE affects the bas e ment of tho.' co ntine ntal crust as well as the sedimentary cover.

3) T hese tecto nic' dements pro bably ta ke part in seismicity of the studv area and its surro unding e xte nsio n .
