Oceanic anoxic eventsGranitoidJapanIn general, the arc magmas are oxidized, forming magnetite-series granitoids. However, there are also ilmenite-series granitoids at convergent margins. The mechanism that controls the formation of different types of granitoids remains obscure. Here we show that the ...
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,...
Through the utilization of seismic tomographic image and relocated seismicity, we identify three potential seismogenic structures along the convergent plate boundary: the Longitudinal Valley Fault, the Ludao–Lanyu Fault, and the Central Range Fault. A significant discovery in our investigation is a ...
In this study, the effects of oceanic mesoscale eddies on the looping path of the Kuroshio intrusion (KI) were symmetrically investigated by composite analysis using merged satellite data. We found that the mesoscale eddies propagating from the east have
(in PE and PP) is more likely controlled by the aqueous boundary layer diffusion (diffusion between particle and water) and not by the internal diffusion in the plastic particle [57,65,69]. For planar passive PE samplers, diffusion across the plastic–water boundary layer is usually the rate...
Post 8 Ma reconstruction of Papua New Guinea and Solomon Islands: Microplate tectonics in a convergent plate boundary setting 2016, Earth-Science Reviews Citation Excerpt : We interpret that the resultant kinematics was expressed by extension and formation of the Feni Deep between the islands of New...
Lower seismic velocities of Vp ¼ B7.7, (and density ¼ B3.0 g cm À 3; Vp/Vs ¼ B1.85), which are similar to the velocities observed at the crust–mantle boundary beneath arcs have been measured in exhumed subduction me´lange rocks with compositions intermediate between chlorite ...
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...
Marine hydrokinetic turbines of MW-level capacity for harvesting oceanic currents are here reviewed. The best design is 3-blades, open rotor, axial flow turbines, of similar design philosophy to wind turbines, which are anchored to the ocean floor. The b
It 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, which solve a second order eigenproblem, are always entire functions or can be computed wholly in terms of entire ...
