The term Great Rift Valley is most often used to refer to the valley of the East African Rift, the divergent plate boundary which extends from the Afar Triple Junction southward through eastern Africa, and is in the process of splitting the African Plate into two new and separate plates. Geo...
The axis of divergent plate boundaries shows extension fractures and normal faults at the surface. Here we present evidence of contraction along the axis of the oceanic ridge of Iceland and the continental Main Ethiopian Rift. Contraction is found at the base of the tilted hanging wall of ...
The boundary between wet and arid climate zones in the Tethys Ocean remains challenging to trace, complicating our understanding of global aridification pattern during the Late Carboniferous to Early Permian transition. The North China Block (NCB), situa
Seafloor spreading is the horizontal divergent plate motion observed at mid-ocean ridges (MORs) (Hess, 1962). ● Subduction is the descent of oceanic lithosphere beneath another tectonic plate to accommodate convergent plate motions (Oliver and Isacks, 1967). ● Ocean-plate tectonics is a mode ...
The passive continental margins are formed under divergentplate boundarysetting. These are aseismic (less seismic) and often referred as the Atlantic-type margins having a distinct transition zone between the continental and oceanic crustal regions. ...
Our models do not include subduction zone plate boundary-induced simple shear, as is also the case for earlier models of India–Asia indentation and Asian deformation9,11,12,19. We note that the simple shear at the continental and oceanic subduction boundaries impose a local deformation on the...
Moreover, we provide a mechanical explanation for the counterclockwise rotation of the continental Victoria microplate in the Nubia–Somalia divergent plate boundary. The edge-driven rotation stems from shear of the major plates along the northwest and southeast corners of the microplate, where both a...
one of the principal elements of the continental margin; it is located between the base of the continental slope and the outer boundary of the ocean floor. (Some investigators consider the continental rise to be part of the ocean floor, drawing the boundary of the continental margin along the...
An example of a divergent plate boundary is a: a. Volcanic island arc b. Mid-ocean ridge c. Transform fault d. Hotspot e. Subduction zone Tectonic plates sliding past one another can cause... A. volcanoes B. constructive plate mar...
Convergent plate margins where large turbidite fans with slivers of oceanic basement are accreted to continents represent important sites of continental crustal growth and recycling. Crust accreted in these settings is dominated by an upper layer of recy
