The passive margins surrounding Africa were formed during breakup of This Paleozoic passive-margin succession including quartzose sandstones, Granulometric and mineralogical characteristics of the Kalahari sands of southern Afric

ABSTRACT Thin beds form an important part of submarine fan deposits. They can be found in five different subenvironments: top of a channel fill, channel margin, levee-overbank area, sandwiched between thick layers in the updip non-channelized depositional lobes, and fan fringe. At the present we are not able to distinguish clearly one depositional subenvironment from the other, using thin beds

Seismic reflection lines across passive margins show many structural features common to both VPM and NVPM, such as faulting and crustal thinning, with the primary contra-indicator for volcanism being the presence of continent-ward dipping reflectors. NVPM also display distinct p-wave velocity structures that differentiate them from VPM. Typical NVPM exhibit a high velocity, high gradient lower crust (6.4-7.7 km/s) overlain by a thin, low velocity (4–5 km/s) upper crustal layer. Passive continental margins are located far (>100s km) from plate boundaries, A passive margin is the transition between oceanic and continental lithosphere that is not an active platemargin. A passive margin forms by sedimentation above an ancient rift, now marked by transitional lithosphere. Continental rifting creates new ocean basins.

Active margins can be convergent or transform margins. A passive margin is the transition between oceanic and continental lithosphere that is not an active plate margin. A passive margin forms by sedimentation above an ancient rift, now marked by transitional lithosphere. Continental rifting creates new ocean basins.

Extension in Red Sea has produced troughs as deep as 2300 m. Rift shoulders line both sides of the rift system, with elevations locally to 3000 m. Continental crust stretches and things by rifting.

Passive continental margins are found along the remaining coastlines. is minimal and the earth's weathering and erosional processes are winning. This leads to lots of low-relief (flat) land extending both directions from the beach, long river systems, and the accumulation of thick piles of sedimentary debrison the relatively The West Coast of the United States is an active margin that is characterized by rugged coastlines with narrow beaches and steep sea cliffs. Passive continental margins occur where the transition between oceanic and continental crust which is not an active plate boundary.

is minimal and the earth's weathering and erosional processes are winning. This leads to lots of low-relief (flat) land extending both directions from the beach, long river systems, and the accumulation of thick piles of sedimentary debrison the relatively Volcanic or magma-rich passive margins are continental margins whose underlying rift basins, developed during the stretching and thinning phases that affected the continental crust before breakup, are totally or predominantly Our study suggests that the architecture of passive margin salt basins is closely linked to the pre- and syn-kinematic cover thickness. The translational domain, as an undeformed region in the supra-salt cover, is a transient feature and overprinted in passive margins with either low sedimentation rate or a heterogeneous sedimentation pattern. Rifts and passive margins are extremely important for the petroleum industry, as they are areas of high sedimentation and can contain significant oil and gas resources.
