How mountains and basins are formed along ocean continent convergent boundaries? In Continent-Ocean (C-O) convergence, the continental volcanic arc formed along the continental plate margin is compressed and is uplifted by the colliding oceanic plate giving rise tofold mountainsalong the continental p...

Convergent - When two tectonic plates come together and collide, the edges of the plates will create a mountain range. Alternatively, the denser tectonic plate will be pushed underneath the other lighter tectonic plate in a process known as subduction. About 80 per cent of earthquakes happen at...
with an overall reduction in seawater Fe quantity surrounding the Antarctic continent (Supplementary Figs.S7a–c). These negative trends can be attributed to the presence of larger amounts of Fe being released from anomalously rapid sea-ice melting, thereby triggering higher rates of Fe uptake64and...
This division implies that there is a highly efficient filter at subduction zones, where the water-rich flux coming off the slab is restricted to the convergent margin and does not escape to “pollute” the rest of the mantle. Where MORB samples have been found that deviate from these ratios...

where, in accordance withplate tectonictheory,lithospheric plates(also called tectonic plates) move apart and new crust is created by magma (molten rock) pushing up from themantle. The mid-ocean ridge system is an example of a divergent (rather than a convergent or transform) plate boundary. ...
(Fig.5). Contemporaneous ophiolitic exposures on eastern Arabian margin15,17,43,44,45,46affirm that the boundary between the two plates was not only transcurrent but also intermittently convergent15,17. This essentially suggests that divergent and convergent phases must have frequently alternated in-...
As a western boundary current, the NBC flows northward along the coast of Brazil (Johns et al., 1990). High nutrient water exported from the Amazon River significantly enhances the biological activities in the NBC. The NBC separates from the Brazil Coast near 7°N and sometimes curves back ...
Thus, the Huanggangliang Formation appears to have been subjected to major southeast-northwest shortening in a convergent setting after its deposition. 4.3.2 Linxi Formation Deformational features in the Linxi Formation (Figure 7) are not as distinct as those in the Huanggangliang Formation (...
