Multiphase Tectonic Process With Slab Dynamics in the Northern East China Sea Shelf Basin
Geological Journal, EarlyView.Megasequence 1 characterised by Palaeocene extension and differential subsidence driven by the rollback of the subducting Izanagi Plate. Megasequence 2 records a kinematic reorganisation of the East Asian margin, transition from a rifting to a compressional regime.

Mitochondrial DNA. Part B. Resources, 2020 Austinograea species are restricted to hydrothermal vents and are typically considered to be omnivorous predators in vent communities. Here we present the complete mitochondrial genome of Austinograea sp. which was collected from Carlsberg Ridge, the mid-

The Energetic 2022 Seismic Unrest Related to Magma Intrusion at the North Mid‐Atlantic Ridge
Geophysical Research Letters, 2023 A seismic swarm affected the 53.3°–54.3° Latitude North section of the Mid‐Atlantic Ridge from 26 September to 10 December 2022. We rely on regional, teleseismic and array data to relocate 61 hypocenters and derive 77 moment tensors.

The influence of mid-ocean ridges on euphausiid and pelagic ecology
, 2012 Chapters 1 & 2. Euphausiids comprise a major component of ecosystems in the pelagic realm, the world’s largest habitat, but basin scale drivers of euphausiids diversity and abundance are poorly understood. Mid-Ocean Ridges are the largest topographical

Geological Journal, EarlyView.Early zircon saturation and crystallisation occur in mafic (52–54 wt.% SiO2) lavas at Tengchong volcanic field. These early formed zircons with high δ18O (6.6‰–7.9‰) indicates mantle enrichment by subducted supracrustal materials. ABSTRACT Late Pleistocene (< 0.2 Ma) mafic and evolved volcanic rocks occur in northern Tengchong Volcanic Field, SE ...

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

Modes of faulting at mid-ocean ridges
Nature, 2005 Abyssal-hill-bounding faults that pervade the oceanic crust are the most common tectonic feature on the surface of the Earth. The recognition that these faults form at plate spreading centres came with the plate tectonic revolution. Recent observations reveal a large range of fault sizes and orientations; numerical models of plate separation, dyke ...

Petrogenesis of lavas from Detroit Seamount: Geochemical differences between Emperor Chain and Hawaiian volcanoes [PDF]
, 2005 The Hawaiian Ridge and Emperor Seamount Chain define a hot spot track that provides an 80 Myr record of Hawaiian magmatism. Detroit Seamount (∼76 to 81 Ma) is one of the oldest Emperor Seamounts.

Observed Linkages Between Marine Heatwaves and Extreme Weather Over Land: A New Zealand Case Study
International Journal of Climatology, EarlyView.Marine heatwaves consistently warm New Zealand's land surface, but rainfall impacts occur only when synoptic systems enable moisture transport. This 38‐year analysis shows MHWs act as thermodynamic background drivers of heat and conditional amplifiers of extreme rainfall events or droughts.

Crustal accretionary processes at mid-ocean ridges - Valu Fa Ridge, Lau Basin [PDF]
, 1998 The structure of oceanic crust is surprisingly uniform, which suggests that crustal accretionary processes at mid-ocean ridges must be broadly similar, despite their different spreading rates and seafloor morphologies.
