Nitrogen Diffusion in Calcite

open access: yesGeophysical Monograph Series, Page 97-104., 2020

This book is Open Access. A digital copy can be downloaded for free from Wiley Online Library.

Explores the behavior of carbon in minerals, melts, and fluids under extreme conditions

Carbon trapped in diamonds and carbonate-bearing rocks in subduction zones are examples of the continuing exchange of substantial carbon ...

A transdisciplinary and community-driven database to unravel subduction zone initiation [PDF]

open access: yesNature 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.

Makran Subduction Zone: A Review and Synthesis

open access: yesGeosciences
This review synthesizes existing research to elucidate the factors driving the distinct tectonic behaviors in the western and eastern Makran subduction zone, focusing on seismic activity, uplift rate, convergence rate, coupling, and subduction angle. The

Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Features of the Largest Earthquake Seismic Cycles in the Western Part of the Aleutian Subduction Zone

open access: yesGeosciences, 2022
We discussed the peculiarities of the seismic cycle in Aleutian subduction zone, characterized by an oblique subduction setting. It was shown that the orientation of the plate convergence vector relative to the subduction zone axis can have a significant

Paleotsunamis on the Southern Hikurangi Subduction Zone, New Zealand, Show Regular Recurrence of Large Subduction Earthquakes

open access: yesThe Seismic Record, 2021
Geological records of subduction earthquakes, essential for seismic and tsunami hazard assessment, are difficult to obtain at transitional plate boundaries, because upper-plate fault earthquake deformation can mask the subduction zone signal.

New Constraints on the Complex Subduction and Tearing Model of the Cocos Plate Using Anisotropic Pn Tomography

open access: yesGeochemistry, Geophysics, Geosystems, 2023
To better understand the structure and process of the Cocos plate subduction, we obtained the first Pn velocity and anisotropy model of the uppermost mantle in southern Mexico using the Pn tomography method and new ISC‐EHB data.

Upper mantle melt caused by a subducted slab in the Indian-Eurasian continental subduction zone

open access: yesCommunications Earth & Environment, 2023
A low-velocity layer atop the mantle transition zone has been extensively observed worldwide. In subduction zones, this layer is widely explained as partial melting triggered by slab subduction on a regional or global scale. However, direct observational

Downgoing Plate‐Buoyancy Driven Retreat of North Sulawesi Trench: Transition of a Passive Margin Into a Subduction Zone

open access: yesGeophysical Research Letters, 2022
The transition of a passive continental margin into a subduction zone remains a hypothesis because few geological cases have been reported. The North Sulawesi subduction zone is a 5–9 myr system in Southeast Asia that has evolved from a passive ...

Body wave dispersion characteristics of regional deep earthquake at Southern Ryukyus subduction zone [PDF]

open access: yesE3S Web of Conferences, 2022
The convergent plate boundaries known as the subduction zone is the location where the cold, hydrate, and old oceanic plate subduct under the hot, dry, and young continental plate. The top of the oceanic plate, i.e. the oceanic crust usually is less than
