Geosciences, 2022 The Lau Basin is a back-arc region formed by the subduction of the Pacific plate below the Australian plate. We studied the regional morphology of the back-arc spreading centers of the Northern Lau basin, and we compared it to their relative spreading ...

Rifting/spreading propagation interacts with preexisting transform faults: 3D geodynamic modeling [PDF]
Frontiers in Earth Science, 2023 The divergent rifting/spreading centers and the strike-slip transform faults are the essential tectonic units on Earth, the dynamic evolution of which regulates the development of rifting/spreading basins. The propagation of rifting/spreading centers may

Oblique seafloor spreading across intermediate and superfast spreading centers
Earth and Planetary Science Letters, 2018 Abstract We show that oblique seafloor spreading occurs in several regions where obliquity, α, was not recognized before. These include the slow spreading centers of the Red Sea ( α ≈ 20 ° ), intermediate spreading centers of the Cocos–Nazca plate boundary between 91°W and 94°W ( α ≈ 9 ° ), and superfast spreading centers of the East ...

Birth of an intraoceanic spreading center
Geology, 2008 The Cocos-Nazca spreading center is one of the few examples of the formation of a spreading center by splitting of oceanic lithosphere. It was created when the Farallon plate, broke up in the early Miocene following the collision of the Pacific-Farallon spreading center with the North American continent. Much of the ancient Farallon plate corresponding

Hydrothermal exploration of the Fonualei Rift and Spreading Center and the Northeast Lau Spreading Center [PDF]
Geochemistry, Geophysics, Geosystems, 2006 We report evidence for active hydrothermal venting along two back‐arc spreading centers of the NE Lau Basin: the Fonualei Rift and Spreading Center (FRSC) and the Northeast Lau Spreading Center (NELSC). The ridge segments investigated here are of particular interest as the potential source of a mid‐water hydrothermal plume (1500–2000 m depth) which ...

Oceanic core complex development at the ultraslow spreading Mid‐Cayman Spreading Center [PDF]
Geochemistry, Geophysics, Geosystems, 2011 Roughly a third of the global mid‐ocean ridge system spreads at <20 mm/yr (full rate) with predicted low crustal thicknesses, great axial depths, end‐member basalt compositions, and prominent axial faults. These predictions are here further investigated along the ultraslow (15–17 mm/yr) Mid‐Cayman Spreading Center (MCSC) through a compilation of ...

Geochemistry, Geophysics, Geosystems, 2011 Most hydrothermal systems at oceanic spreading centers are underlain by basaltic magma bodies; however, some are underlain by higher‐silica magmas such as andesite or dacite.

Geodynamic Models of Melt Generation and Extraction at Mid-Ocean Ridges [PDF]
Oceanography, 2012 It is widely accepted that plate divergence at mid-ocean ridges drives mantle flow, mantle melting, and the formation of new oceanic crust. However, many of the details of this process remain obscure because of the inaccessibility of the mantle to direct

Estimating Zooplankton Biomass Distribution in the Water Column Near the Endeavour Segment of Juan de Fuca Ridge Using Acoustic Backscatter and Concurrently Towed Nets [PDF]
Oceanography, 2012 Logistical challenges, time, and the cost of towed net surveys make it difficult to obtain estimates of secondary biomass and production in the open ocean outside the summer sampling season. Alternate approaches are sometimes needed.
