Located on opposite margins of the West
Rub' al Khali basin, two structural trends of the Central Arabia and Eastern
Arabia share a general north-south structural orientation and similar
transpressional structural styles in the Carboniferous Hercynian Orogeny.
Multiple seismic profile and map geometry criteria (Harding, 1990) are used to
identify the magnitude and direction of strike-slip faulting for the two
trends.
Transpressional structures in
Recent 3D seismic interpretation of the
structural trend on the east basin margin indicates a left-lateral
transpressional system, with much smaller strike-slip component. Most fault
planes are sub-parallel but discontinuous along the strike, as opposed to their
through-going and solitary counterparts in the
