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 per
The vast majority of volcanism on Earth occurs at spreading and convergent plate boundaries (e.g., mid-oceanic ridges and subduction zones), whereas there are also volcanoes far from these plate boundaries, such as the Changbaishan-Tianchi volcano within the continent of northeastern Asia (e.g....
Earthquake & tectonic plates. Earth structure and plate boundaries categories: Transform boundaries, Convergent boundaries (Subduction boundaries, Collisional boundaries)
Comparison of numerical results to existing natural examples suggests that in nature, STEP-faults follow convergent paths that could be controlled by intense fractures weakening due to deep water penetration into the relatively cold oceanic lithosphere of the present-day Earth....
Convergent Power Series for Boundary Value Problems and Eigenproblems with Application to Atmospheric and Oceanic TidesIt is usually impossible to apply power series to solve boundary value and eigenvalue problems because the radius of convergence does not extend to the boundaries. Hough functions, ...
Convergent morphology of the plankton represents adaptations for suspension in the water column, for movement within this water mass to increase nutrient uptake, and for protection against grazing or predation. Necessary attributes for cosmopolitan species include eurythermy and euryhalinity. The ...
This difference in number of events was proposed to be due to the presence of a serpentinized mantle layer overlying a pristine mantle layer located below 30–35 km down to the base of the lithosphere located at ~60 km, with a large stress drop occurring at the boundary between the ...
Equatorward alongshore winds over major eastern boundary upwelling systems (EBUSs) drive intense upwelling via Ekman dynamics, surfacing nutrient-rich deep waters and promoting marine primary production and fisheries. It is generally thought, dating back
This chapter overviews global and local features of oceanic trenches. Most oceanic trenches are associated with plate subduction boundary systems; they form due to the downward bending of an oceanic plate entering a subduction system. Their total length is 47,900 km, longer than Earth’s circumfere...
convergent margins due to the addition of subducted crustal materials (including volatile components and/or melts). OIBs and CFBs are genetically related to mantle plumes, which originate from the lower mantle or the core-mantle boundary11. A landmark study recently observed deviations in Δ199Hg...
