| Zusammenfassung |
| The Oligo-Miocene Gulf of Suez rift is characterized by four fault trends; a rift-parallel trend,
two trends oblique to the rift trend and a cross trend. The rift-parallel trend strikes 310o to
340o and is referred to as the Clysmic trend. The two trends, which are oblique to the
Clysmic trend, strike 350o to 030o and 280o to 310o; the first has been referred to as the
north-oblique (N-oblique), and the second as the northwest-oblique (NW-oblique). The cross
trend includes faults nearly orthogonal to the Clysmic trend i.e. they strike between 050o and
075o.
Image interpretation and detailed field mapping and structural studies at a scale of 1:
20,000 of the Wadi Araba area in southwest Sinai Peninsula indicate e Clysmic faults are
mostly normal showing major dip-slip movements. The oblique faults were found to be
younger than the Clysmic faults and that the N-oblique faults are characterized by major
sinistral strike-slip movement, while the NW-oblique faults are characterized by major
dextral strike-slip movement. Cross cutting relationship, geometry and palaeostress analysis
indicate that the oblique faults are conjugate Riedel shears originated due to NE to NNE
extension related to the Aqaba-Levant transform that has been active since the Middle
Miocene. |
