Image: Magma up swelling from deep within the Earth occurs when divergent plates spread apart 2. Transform boundaries (also called transform faults) These are found where plates slide past one another. The San Andreas Fault is an example of a transform -fault plate boundary along the north west...
These plates are actually sliding apart, called adivergent boundary. Because they are sliding apart, hot liquid lava can come out from below the crust. That's what forms the ridge and new oceanic crust. Oceanic Crust Plate Boundaries
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 ...
A mid-oceanic ridge, for example the Mid-Atlantic Ridge, has examples of volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has examples of volcanoes caused by convergent tectonic plates coming together. The Volcano Registry Street directories and a wide variety ...
1. Introduction Ophiolites, preserved as obducted slivers of ancient oceanic litho- sphere in Precambrian and Phanerozoic orogenic belts and on continen- tal margins, provide the most conspicuous and robust perspectives on intraoceanic divergent and convergent margin tectonics, mantle hetero- geneity,...
Ancient oceanic plateaus, often generated at triple junctions or divergent plate boundaries, are believed to be important building blocks in the formation of the continental lithosphere (Kerr et al., 2000). Seismic structure of the plateau lithosphere is probably more complicated than that in the ...
1): STEP-faults could either exhibit divergent fracturing paths, leading to the consumption of increasingly large portions of the oceanic floor; or parallel fracturing paths, consuming a band of oceanic floor of constant-width; or convergent fracturing paths, resulting in a narrowing of the ...

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 recycled crustal and arc detritus (turbidites) underlain...
The comparison between experimental and natural examples suggests that the observed wide spectrum of ridge interaction types in nature results from the initial configuration of the divergent plate boundary.Tatiana TentlerDepartment of Geology and MineralogyRoyal Museum for Central AfricaJournal of Geophysical...
