(less than 200 million years); that new oceanic lithosphere forms along crests of oceanic ridges; that older oceanic lithosphere is resorbed beneath linear trends of deep focus earthquakes associated with oceanic trenches; that extensive plates of the earth's lithosphere move laterally at rates up ...
The type of lithosphere subducted between India and Tibet since the Paleocene remains controversial; it has been suggested to be either entirely continental, oceanic, or a mixture of the two. As the subduction history of this lost lithosphere strongly shaped Tibetan intraplate tectonism, we attempt...
However, the data also revealed many features that the theory did not anticipate – mid-ocean ridges that propagated into old, thick oceanic lithosphere; spreading centers that overlapped (sometimes forming microplates that rotate rapidly between larger plates for a few million years); and a very ...
(z,∞) is the equilibrium lithosphere temperature after thermal perturbation; tc is initial crust thickness;ρw is seawater density;ρc is crust density;ρm is mantle density; α is the coefficient of thermal expansion; Tm is the temperature at the bottom of the lithosphere; β is a crustal...
The oceanic magnesium budget is important to our understanding of Earth’s carbon cycle, because similar processes control both (e.g., weathering, volcanism, and carbonate precipitation). However, dolomite sedimentation and low-temperature hydrothermal c
Typical continental arcs occur at the western margin of the North and South American, and the Sunda arc in the northeastern margin of the Indian Ocean, where oceanic lithosphere is subducted beneath continental lithosphere without a marine basin behind the volcanic arc; rather, the arc is built ...
Spreading centers formed within the rheologically weaker protocontinental margins surrounded by stronger oceanic lithosphere in the Solomon and Coral Seas. The transition to spreading occurred after a rather uniform degree of continental extension: 200±40 km. Both early and late stage rifting involved ...
Geodynamics of oceanic plateau and plume head accretion and their role in Phanerozoic orogenic systems of China[J]. Geoscience Frontiers, 2015, 6(1): 49-59. DOI: 10.1016/j.gsf.2014.07.002 [10] Michael Brown. The contribution of metamorphic petrology to understanding lithosphere evolution and ...
We use trace element and isotope (Sr, O) geochemistry to determine the protoliths to the metasomatized rocks and establish the nature and timing of metasomatism, which provides the first direct constraints on the timing of juxtaposition between oceanic and continental lithosphere at the base of ...
In the Alpine–Carpathian mountain belt, the majority of (U)HP/LT units are related to the Paleogene subduction of the Pennine oceanic lithosphere and attached continental slivers. These are widespread in the Western Alps (e.g. Pleuger et al. 2007; Weber et al. 2015 and references therein)...
