On the origin of the North Pacific arcs [PDF]

open access: yes, 2004
We present a new hypothesis that relates global plate tectonics to the formation of marginal basins, island arcs, spreading ridges and arc-shaped mountain belts around the North Pacific Ocean.

A Global Plate Model Including Lithospheric Deformation Along Major Rifts and Orogens Since the Triassic [PDF]

open access: yes, 2019
Global deep‐time plate motion models have traditionally followed a classical rigid plate approach, even though plate deformation is known to be significant.

The Billefjorden Fault Zone north of Spitsbergen: a major terrane boundary?

open access: yesPolar Research, 2021
The Billefjorden Fault Zone is a major terrane boundary in the Norwegian Arctic. The fault separates basement rocks of Svalbard’s north-eastern and north-western terranes that recorded discrete Precambrian tectonothermal histories and were accreted ...

Fe/N‐Doped Carbon with Nearly Ordered Mesopores and Tunable Particle Sizes as Model Catalysts for Quantitative Evaluation of Electrocatalytic Active Sites

open access: yesAdvanced Science, EarlyView.
This study is dedicated to the design and synthesis of MOF‐derived mesoporous Fe/N‐doped carbons as model catalysts, aiming to quantitatively evaluate the utilization of active sites in the ORR. Through modulation followed by pyrolysis, we successfully prepare size‐tunable Fe/MNC‐x with doped iron atoms and mesoporous structures. The smaller Fe/MNC‐250

Neogene plate tectonic reconstructions and geodynamics of North Island sedimentary basins: Implications for the petroleum systems [PDF]

open access: yes, 2006
Although the modern Australia-Pacific plate boundary through New Zealand is relatively straight, there have been significant changes in its geometry during the Neogene. Within the North Island sector there has been a fundamental transition from an Alpine

Plate Tectonics

open access: yes, 2019
Plate tectonics is the root concept underpinning our current knowledge of how Earth's internal dynamics are linked to geologic deformation at the surface. Since the discovery of plate tectonics in the 1960s, geoscientists have developed a first-order understanding of a plate system in which the Earth's surface is broken into about a dozen mostly rigid ...
