A transdisciplinary and community-driven database to unravel subduction zone initiation
Nature Communications, 2020 Despite numerous advances in our understanding of subduction since the theory of plate tectonics was established, the mechanisms of subduction zone initiation remain highly controversial.

The Norfolk Ridge: A Proximal Record of the Tonga‐Kermadec Subduction Initiation
Geochemistry, Geophysics, Geosystems, 2023 Norfolk Ridge bounds the northeastern edge of the continent of Zealandia and is proximal to where Cenozoic Tonga‐Kermadec subduction initiation occurred.

Kinematic evolution of the Southern Andean orogenic arc [PDF]
, 2016 In the classic book ‘Origin of Continents and Oceans’ written 40 years before the plate tectonics theory was postulated, Alfred Wegener suggested that map-view curvatures in orogenic belts were the result of the motion of continents.

Subduction initiation and ophiolite crust: new insights from IODP drilling [PDF]
, 2017 International Ocean Discovery Program (IODP) Expedition 352 recovered a high-fidelity record of volcanism related to subduction initiation in the Bonin fore-arc. Two sites (U1440 and U1441) located in deep water nearer to the trench recovered basalts and

Plate motion and plume-induced subduction initiation [PDF]
, 2021 Impingement of a hot buoyant mantle plume head on the lithosphere is one of the few scenarios that can initiate a new subduction zone without requiring any pre-existing weak zones. This mechanism can start subduction and plate tectonics on a stagnant lid

DataSheet1_Kinematic Boundary Conditions Favouring Subduction Initiation at Passive Margins Over Subduction at Mid-oceanic Ridges.docx [PDF]
, 2021 We perform numerical modelling to simulate the shortening of an oceanic basin and the adjacent continental margins in order to discuss the relationship between compressional stresses acting on the lithosphere and the time dependent strength of the mid ...

Plume-Induced Subduction Initiation: Revisiting Models and Observations
Frontiers in Earth Science, 2021 Subduction initiation induced by a hot and buoyant mantle plume head is unique among proposed subduction initiation mechanisms because it does not require pre-existing weak zones or other forces for lithospheric collapse.

Patterns of Late Cenozoic exhumation deduced from apatite and zircon U-He ages from Fiordland, New Zealand [PDF]
, 2005 New apatite and zircon (U-Th)/He ages from the Fiordland region of New Zealand's South Island expand on earlier results and provide new constraints on patterns of Late Cenozoic exhumation and cooling across this region.
